Ingredients

Ingredients for Peanut Butter Cupcakes - peanut butter, flour, powdered sugar, butter, Reese's Cups, butter, vanilla, eggs.

For the Cupcakes:

  • All-Purpose Flour. This is the structural foundation for our fluffy cupcakes. For the most accurate measurement and to prevent a dense cupcake, *spoon* the flour lightly into your measuring cup, then level it off with a straight edge. Never scoop directly from the bag, as this can compact the flour and add too much to your batter.
  • Baking Powder & Baking Soda. These are our leavening agents, working in tandem to give the cupcakes their perfect rise and light, airy texture. Ensure they are fresh for optimal results!
  • Salt. A pinch of salt is crucial. It balances the sweetness and enhances the overall peanut butter flavor, making it pop even more.
  • Vegetable Oil. This is key for creating an incredibly moist and tender crumb. Unlike butter, oil remains liquid at room temperature, contributing to a softer, more consistently moist cupcake that stays fresh longer.
  • Creamy Peanut Butter. The star of the show! For both the cupcakes and the frosting, creamy peanut butter is highly recommended. Its smooth consistency ensures a uniform texture and rich flavor throughout. Avoid natural peanut butter with separated oil, as it can alter the texture significantly. Brands like Jif or Skippy work wonderfully.
  • Light Brown Sugar. Adds moisture and a lovely caramel-like depth of flavor that complements the peanut butter beautifully. Make sure it’s packed firmly in your measuring cup. If you’re feeling ambitious, you can even try a homemade brown sugar recipe!
  • Large Egg. Provides structure, richness, and helps bind the ingredients together. Using a room-temperature egg ensures it incorporates more smoothly into the batter, leading to a more uniform and tender cupcake.
  • Sour Cream. A secret ingredient for incredible moisture and a subtle tang that enhances the flavor profile without being overtly sour. It contributes to a rich, velvety texture.
  • Whole Milk. Adds moisture and helps achieve the perfect batter consistency. Whole milk is preferred over reduced-fat options for its richness, which contributes to a more decadent cupcake.
  • Vanilla Extract. Use pure vanilla extract for the best flavor. Don’t skimp on good vanilla! Pure vanilla extract elevates all the other flavors, adding a warm, aromatic note that is essential for a truly delicious cupcake.

For the Frosting:

  • Butter. Make sure to use real butter. Ensure it’s softened to room temperature for easy creaming, resulting in a light and fluffy texture.
  • Creamy peanut butter. Creamy peanut butter is essential here for that signature smooth, pipeable frosting. Its consistent texture is key to a beautiful finish.
  • Powdered Sugar. Also known as confectioners’ sugar, this provides the sweetness and structure for the frosting. Sifting it is a critical step to prevent lumps and ensure a silky-smooth finish.
  • Whole Milk. Used to adjust the frosting consistency. Start with the minimum amount and add more slowly until your desired spreadable (or pipeable) texture is achieved.

For the Topping:

  • Miniature Reese’s Peanut Butter Cups. The mini size, cut in half, is perfect for cupcake decoration. These iconic candies are the ultimate garnish, adding an extra burst of chocolate and peanut butter flavor, and a delightful textural contrast.

Equipment You’ll Need

Having the right tools can make your baking experience much smoother and more enjoyable. For these Peanut Butter Cupcakes, you’ll need a few common kitchen essentials:

  • Standard Muffin Tin: For baking your cupcakes.
  • Cupcake Liners: To ensure easy removal and a clean presentation.
  • Large Mixing Bowls: At least two – one for dry ingredients and one for wet.
  • Whisk: For combining dry ingredients and initially mixing wet ingredients.
  • Electric Mixer (Stand or Hand-held): Absolutely essential for creaming butter and peanut butter for the frosting to achieve that light and fluffy consistency.
  • Measuring Cups and Spoons: For accurate ingredient measurement.
  • Rubber Spatula: For scraping down bowls and gently folding ingredients.
  • Wire Rack: For cooling your cupcakes completely before frosting.
  • Piping Bag and Tip (optional): For a professional-looking frosting swirl, but a knife or offset spatula works just as well for spreading.

Variations and Additions

  • Chocolate cupcakes. For a delicious twist, swap the peanut butter cupcake base for rich Chocolate Cupcakes, creating a classic chocolate peanut butter combination.
  • Topping. Beyond Reese’s Cups, get creative with your toppings! Reese’s Pieces, chopped Hershey Bars, dark chocolate shavings, crushed Homemade Nutter Butter Cookies, and Hershey Kisses also make fantastic and visually appealing topping ideas.
  • Mini Cupcakes. Turn these into delightful bite-sized treats by using a mini muffin tin. Adjust baking time accordingly (usually 10-12 minutes).
  • Peanut Butter Drizzle. For an extra layer of peanut butter goodness, drizzle a little melted creamy peanut butter over the top of the frosted cupcakes.

Step by Step Instructions

Let’s get baking! Follow these simple steps to create your own batch of delicious peanut butter cupcakes.

  • Step 1: Prepare Your Workspace and Oven. Begin by preheating your oven to 350°F (175°C). This ensures your oven is at the correct temperature when the batter is ready, promoting even baking. Line a standard 12-cup muffin pan with cupcake liners. If making a larger batch, prepare a second pan.
  • Step 2: Combine Dry Ingredients. In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Whisking ensures these ingredients are evenly distributed, which is crucial for proper leavening. Set this bowl aside.

Step 3: Mix Wet Ingredients. In a separate large bowl, whisk together the creamy peanut butter, brown sugar, vegetable oil, large egg, sour cream, whole milk and vanilla extract. Use a whisk or an electric mixer on low speed to thoroughly blend these ingredients until smooth and well-incorporated. This creates the rich, moist base for your cupcakes.

Step 4: Combine Wet and Dry. Create a slight well in the center of your dry ingredients. Pour the wet mixture into this well. Using a rubber spatula or an electric mixer on very low speed, gently stir until just combined. *Be careful not to overmix!* Overmixing develops gluten, which can lead to tough, dry cupcakes. A few small lumps are perfectly fine.

Step 5: Fill Liners and Bake. Divide the cupcake batter evenly among the prepared muffin liners, filling each approximately two-thirds full. This allows room for the cupcakes to rise without overflowing. Place the muffin tin into your preheated oven and bake for 20-23 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.

Step 6: Cool Completely. Once baked, remove the cupcakes from the oven. Let them cool in the muffin tin for about 5 minutes before carefully transferring them to a wire rack to cool completely. It’s vital that the cupcakes are entirely cool before frosting, otherwise, your beautiful frosting will melt!

Step 7: Prepare the Peanut Butter Frosting. While your cupcakes are cooling, it’s time to make the luscious peanut butter frosting. In a medium mixing bowl, using a stand mixer with a paddle attachment or a hand-held electric mixer, cream together the softened butter and creamy peanut butter on medium speed until the mixture is light, fluffy, and well combined. This can take 2-3 minutes.

Powdered sugar added to mixture and combined.

Step 8: Add Powdered Sugar and Milk. Gradually add the powdered sugar to the butter and peanut butter mixture, alternating with small splashes of whole milk. Begin with 2 tablespoons of milk and add more if needed. Beat on low speed until the sugar is incorporated, then increase to medium-high and beat until the frosting is smooth, creamy, and reaches your desired consistency. If it’s too thick, add a tiny bit more milk; if too thin, add a little more powdered sugar.

Step 9: Frost and Garnish. Once the cupcakes are completely cool, transfer the frosting to a piping bag fitted with your favorite tip (or use a ziploc bag with the corner snipped off, or simply spread with a knife). Swirl a generous amount of frosting onto each cupcake.

Frequently Asked Questions

How to store these delicious cupcakes?

To maintain their freshness and flavor, place any leftover Peanut Butter Cupcakes in an airtight container. Store them in the refrigerator for up to 5 days. Bringing them to room temperature for about 15-20 minutes before serving can enhance their texture and flavor, making them softer and more enjoyable.

Can you use natural peanut butter?

We do not recommend using natural peanut butter for this recipe, especially for the frosting. Natural peanut butter tends to separate its oils, which can drastically alter the texture of both the cupcake and the frosting, making them oily or grainy. For the best, most consistent results and a smooth, creamy frosting, stick to classic creamy peanut butter brands like Jif or Skippy, which are consistently emulsified.

Can I make these cupcakes ahead of time?

Absolutely! The unfrosted cupcakes can be baked one day in advance and stored in an airtight container at room temperature. The frosting can also be made a day ahead and refrigerated in an airtight container; just bring it to room temperature and re-whip it for a minute or two before frosting your cooled cupcakes. This advanced preparation makes party planning much easier!

Can I freeze Peanut Butter Cupcakes?

Yes, you can! For best results, freeze the unfrosted cupcakes. Wrap each cooled cupcake individually in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Thaw them at room temperature for a few hours before frosting and serving. You can also freeze the frosting separately in an airtight container for up to 1 month; thaw in the refrigerator overnight and re-whip before using.

What if my frosting is too thick or too thin?

Frosting consistency is key! If your frosting is too thick, add milk (or a tiny bit of heavy cream) one teaspoon at a time, beating after each addition, until it reaches your desired consistency. If it’s too thin, gradually add more powdered sugar, one tablespoon at a time, until it thickens up. Always make small adjustments to avoid overcorrecting and ensure a perfect spreadable or pipeable texture.

Pro Tips

Achieving the perfect peanut butter cupcake is all about a few key details. Keep these pro tips in mind for baking success:

  • Room Temperature Butter for Frosting. This is a golden rule for baking! Softened butter creams much more smoothly with peanut butter and powdered sugar, resulting in a light, airy, and lump-free frosting with a superior creamy texture. If your butter is too cold, your frosting will be clumpy; if too warm, it might be greasy or too runny.
  • Don’t Overmix the Cupcake Ingredients. Once the wet and dry ingredients are combined, mix only until just incorporated. Overmixing develops the gluten in the flour, leading to tough, dense, and chewy cupcakes rather than the moist, tender ones we’re aiming for. A few small lumps are perfectly acceptable and often indicate you haven’t overmixed.
  • Creamy Peanut Butter is Best. While chunky peanut butter is delicious on its own, for both the cupcake batter and especially the frosting, creamy peanut butter provides the smoothest, most consistent texture. This ensures your cupcakes are uniformly soft and your frosting is silky and easy to pipe or spread. Brands like Jif or Skippy are ideal due to their consistent emulsification.
  • Cool Cupcakes Completely Before Frosting. Patience is a virtue, especially in baking! Frosting warm cupcakes will inevitably lead to melted, messy frosting. Allow your cupcakes to cool completely on a wire rack to room temperature – this can take up to an hour – before applying any frosting. This step is non-negotiable for beautiful results.
  • Measure Flour Correctly. As mentioned in the ingredients, always spoon flour lightly into your measuring cup and level it off with a straight edge. Scooping directly can compact the flour and add up to 25% more than needed, resulting in dry, dense cupcakes.
  • Don’t Overfill Cupcake Liners. Filling liners about two-thirds full is the sweet spot. Overfilling can lead to cupcakes overflowing and creating a messy “muffin top” that’s hard to frost, or even collapsing and sinking as they cool.
