My recent freelance work creating new recipes for Peanut Butter & Co has only deepened my undeniable love affair with peanut butter.

Why These Peanut Butter Caramel Cupcakes Are Your Next Must-Bake Dessert
There are countless reasons why this Peanut Butter Caramel Cupcake recipe stands out as a true gem in the world of desserts. If you’re looking for a showstopper that will impress guests or simply a divine treat for yourself, look no further. Here’s what makes them so utterly irresistible and a perfect addition to your baking repertoire:
The Foundation: A Fluffy Peanut Butter Cupcake Base
Our journey to cupcake perfection begins with the cake itself. Forget dry, dense cakes; these are meticulously designed to be supremely moist, incredibly light, and wonderfully tender, all while being infused with an authentic, rich peanut butter flavor. We incorporate smooth peanut butter directly into the batter, ensuring that distinct nutty taste is present in every single crumb. The careful balance of ingredients, including buttermilk, contributes to their airy texture and delightful crumb, making them a joy to eat even before they’re adorned with frosting and fillings.
The Sweet Surprise: Gooey Caramel Filling
What’s better than a delicious cupcake? A delicious cupcake with a delectable surprise center! Each of these treats is thoughtfully cored and filled with a generous dollop of luscious, golden caramel. This hidden layer adds an incredible burst of sweetness and a wonderfully gooey, melt-in-your-mouth texture that perfectly complements the robust peanut butter flavor. It’s an unexpected delight that transforms these cupcakes from simply good to absolutely extraordinary, creating an exciting contrast with every bite.
The Crown Jewel: The Best Peanut Butter Buttercream Frosting
Prepare yourself for the frosting experience of a lifetime. This isn’t just any peanut butter frosting; it’s *the* ultimate peanut butter buttercream. Crafted with softened cream cheese, rich unsalted butter, and a generous amount of smooth peanut butter, it’s whipped to an ethereal lightness and unparalleled creaminess. The powdered sugar is carefully sifted to ensure a silky-smooth texture, free of any grittiness, while a hint of vanilla extract and a pinch of salt expertly balance the sweetness and enhance the overall depth of flavor. It’s rich, velvety, intensely peanut buttery, and quite simply, unforgettable – truly earning its “Wonder of the World” title.
The Finishing Touch: Decadent Drizzles and a Satisfying Crunch
To complete this masterpiece, each cupcake receives a final artistic flourish that is as crucial to the taste as it is to the presentation. A decadent drizzle of extra caramel cascades gracefully over the smooth buttercream, creating inviting patterns and adding another layer of sweet indulgence and visual appeal. Finally, a sprinkle of finely chopped roasted peanuts provides a delightful textural contrast, adding a satisfying crunch that elevates the entire experience. These elements aren’t merely for decoration; they are integral to the full sensory journey of these magnificent Peanut Butter Caramel Cupcakes.
Expert Baking Tips: Achieve Perfect Cupcakes Every Time
Baking perfect cupcakes can seem daunting, but with a few simple techniques, you’ll be turning out bakery-quality treats in no time. Follow these expert tips to ensure your Peanut Butter Caramel Cupcakes are consistently delightful and perfectly baked:
- Use a Measuring Scoop for Even Batter Distribution: This is a game-changer for achieving uniform results. Using a standard ice cream scoop or a specific measuring scoop (like this one I use) to portion equal amounts of batter into each cupcake liner ensures that all your cupcakes bake evenly. This prevents some from being overdone while others are underbaked, leading to a consistent batch with identical texture and appealing appearance.
- Don’t Overfill Your Cupcake Liners: A common mistake that can lead to flat, overflowing, or misshapen cupcakes. Cupcakes rely on the supportive walls of the liner or muffin pan to help them rise properly and form that lovely domed top. If you fill them more than 2/3 full, there’s too much batter and not enough structural support to climb, causing the batter to spill over the sides and flatten. Aim for about half to two-thirds full for optimal rise and a beautifully rounded shape.
- Resist the Urge to Open the Oven Door During Baking: Patience is truly key in baking, especially with delicate items like cupcakes. Opening the oven door, even for a quick peek, causes a sudden and significant drop in temperature within the oven. Small cupcakes are particularly susceptible to this change, which can lead to them sinking in the middle, resulting in dense or deflated treats. Trust your oven and the recommended baking time; use the oven light to observe their progress.
- Know When Your Cupcakes Are Done: You can often tell your cupcakes are ready without constantly opening the oven! Use your oven light to observe them; they should appear nicely domed and set. Once they look ready, you can gently open the door and lightly touch the tops. If they spring back gently when pressed, they’re done. For absolute certainty, another reliable test is inserting a clean toothpick into the center of a cupcake; if it comes out clean, they’re perfectly baked through.
- Cool Cupcakes in the Pan for a Short Period, Then Transfer to a Rack: After removing your freshly baked cupcakes from the oven, allow them to cool in the muffin pan for approximately 5 minutes. This brief period allows them to set slightly and become firm enough to handle without falling apart. However, it’s crucial not to leave them in the hot pan for too long, as the residual heat can continue to cook them, leading to dry, overbaked cupcakes. Transfer them to a wire cooling rack to cool completely, ensuring proper airflow all around for a perfectly moist and tender result.

Ingredients
Cupcakes:
- ½ cup smooth peanut butter (135 grams)
- 1 cup granulated sugar (200 grams)
- 1 ½ cups all-purpose flour (200 grams)
- 1 ½ teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup buttermilk (175 ml)
- 2 large eggs
- 1 teaspoon vanilla extract
Frosting:
- 4 ounces cream cheese , at room temperature (113 grams)
- ¼ cup unsalted butter , at room temperature (56 grams)
- ⅓ cup smooth peanut butter (90 grams)
- 2 cups powdered sugar , sifted (450 grams)
- ½ teaspoon vanilla extract
- Pinch of salt
- 1-2 tablespoons milk or cream
For assembly:
- 1 cup caramel , see Note
- ½ cup peanuts (70 grams)
Instructions
To make the cake:
-
Preheat oven to 350° F (175° C). Line a muffin pan with cupcake liners or grease with butter or nonstick cooking spray. This prepares your pan for easy removal and prevents sticking.
-
In the bowl of a stand mixer fitted with a paddle attachment, or in a large bowl with a hand-held mixer, beat the peanut butter and granulated sugar on high speed until light and fluffy. Continue mixing until the mixture sticks slightly to the sides of the bowl. This creaming process should take about 4-5 minutes, incorporating air for a tender crumb.
-
In a separate medium bowl, combine the all-purpose flour, baking powder, baking soda, and salt, whisking them together thoroughly. In a third small bowl, whisk together the buttermilk, large eggs, and vanilla extract until well combined. Alternately add the wet and dry ingredients to the peanut butter mixture in the mixer in 3 additions, starting and ending with the dry ingredients. Mix until just combined after each addition; do not overmix.
-
Spoon the batter evenly into the prepared cupcake liners, filling each cup only half way (about 2/3 full maximum is also acceptable, but be mindful not to overfill). Bake for 14-16 minutes, or until the tops spring back when lightly touched and a toothpick inserted into the center of a cupcake comes out clean. Let cool completely in the pan for 5 minutes, then transfer to a wire rack to finish cooling.
To make the frosting:
-
In a large bowl with a hand mixer or in a stand mixer, beat the softened cream cheese, unsalted butter, smooth peanut butter, sifted powdered sugar, vanilla extract, and a pinch of salt together until the mixture is smooth and well combined. Add 1-2 tablespoons of milk or cream, a little at a time, until you achieve a light, fluffy, and easily spreadable consistency. Beat on high for another 1-2 minutes until the frosting is exceptionally light and creamy.
To assemble the cupcakes:
-
Once the cupcakes are completely cool, use a small knife or a cupcake corer to cut a small well, approximately 1 inch deep, into the tops of each cupcake. Carefully spoon about 1 teaspoon of the caramel into each well. Ensure it does not overflow, as you’ll be covering it with frosting.
-
Top each caramel-filled cupcake generously with the prepared peanut butter frosting. You can do this elegantly with a piping bag and a decorative tip, or simply use a knife or offset spatula for a charming homemade look. Drizzle the frosted cupcakes with more caramel for an extra touch of decadence and finally, sprinkle with chopped peanuts for texture and visual appeal.
-
Store assembled cupcakes in an airtight container in the refrigerator to maintain their freshness and the stability of the cream cheese frosting.
Notes
Customization and Serving Suggestions for Your Peanut Butter Caramel Cupcakes
While this recipe delivers an absolutely perfect cupcake as written, don’t hesitate to get creative and make them your own! These Peanut Butter Caramel Cupcakes are wonderfully versatile, allowing for delightful variations and personalized touches to suit any palate.
Personalizing Your Cupcakes:
- Peanut Butter Choice: For an extra layer of texture and a bolder nutty flavor, consider incorporating a portion of crunchy peanut butter into the cupcake batter. You could even swirl a small amount into the frosting, though be aware it might slightly alter the frosting’s traditionally smooth consistency.
- Caramel Variations: The recipe suggests using store-bought caramel ice cream topping for convenience, or you can make your own rich, homemade caramel for an even deeper, more nuanced flavor profile. For a sophisticated twist that perfectly complements the sweetness, try using a good quality salted caramel.
- Additional Fillings: If you’re a devout chocolate lover, elevate these treats further by adding a small amount of chocolate ganache or even a mini peanut butter cup into the core of the cupcake before frosting, either alongside or as an alternative to the caramel filling.
- Topping Creativity: Beyond the classic chopped peanuts, feel free to get creative with your toppings. Consider adding mini chocolate chips, a delicate sprinkle of flaky sea salt (which truly enhances the caramel’s flavor), or even small pieces of your favorite peanut butter candy bar for the ultimate indulgence.
Serving Ideas:
- The Classic Way: For a comforting and timeless experience, serve these cupcakes at room temperature with a tall glass of cold milk or a warm cup of freshly brewed coffee. The contrast in temperatures and flavors is simply divine.
- Dessert Platter Star: These visually appealing cupcakes make a fantastic addition to any dessert spread. Arrange them beautifully on a platter for parties, gatherings, or special occasions; their irresistible charm and flavor are sure to make them a centerpiece.
- Gift of Sweetness: Baked goods are always appreciated! These Peanut Butter Caramel Cupcakes make a thoughtful and delicious homemade gift. Package them in a lovely box and share them with friends, family, or colleagues for a gesture that’s sure to bring smiles.
Storing Your Decadent Peanut Butter Caramel Cupcakes
To maintain their freshness, preserve their moist texture, and ensure their delicious flavor, proper storage is absolutely essential for these delightful cupcakes. Especially with the cream cheese in the frosting and the caramel filling, it’s important to store them correctly to enjoy them at their best.
- Refrigeration is Key: Due to the presence of cream cheese in the rich buttercream frosting, these cupcakes must always be stored in an airtight container in the refrigerator. This not only keeps the frosting stable and prevents it from melting or spoiling but also helps to keep the cupcakes themselves from drying out too quickly.
- Bring to Room Temperature (Optional, but Recommended): For the most enjoyable flavor and texture experience, particularly for the cake and the gooey caramel filling, I recommend removing the cupcakes from the refrigerator about 15-30 minutes before serving. This allows them to warm up slightly, making the cake softer, the frosting creamier, and the caramel a bit gooier, significantly enhancing the overall indulgence.
- Shelf Life: When stored properly in an airtight container in the refrigerator, these Peanut Butter Caramel Cupcakes will remain wonderfully fresh and delicious for up to 3-4 days. While they might still be edible after this period, their peak quality, taste, and texture will gradually start to decline.
- Freezing for Later: If you find yourself with a large batch or simply wish to save some for a future craving, unfrosted cupcakes can be frozen successfully for up to 2-3 months. To do so, wrap each cooled cupcake individually in plastic wrap, then place them in an airtight freezer-safe bag or container. When you’re ready to enjoy, thaw them at room temperature and then frost as desired. Frosted cupcakes can also be frozen, though it’s worth noting that the frosting’s texture might slightly alter upon thawing.
