Ingredients

Here’s everything you need to whip up these delectable peanut butter cupcakes:

For the Cupcakes

Ingredient	Quantity
All-purpose flour	1 ½ cups
Baking powder	1 ½ tsp
Baking soda	½ tsp
Salt	¼ tsp
Unsalted butter (softened)	½ cup
Creamy peanut butter	¾ cup
Granulated sugar	¾ cup
Brown sugar (packed)	½ cup
Eggs	2
Vanilla extract	1 tsp
Whole milk	½ cup
Sour cream (optional, for extra moisture)	¼ cup

For the Peanut Butter Frosting

Ingredient	Quantity
Unsalted butter (softened)	½ cup
Creamy peanut butter	1 cup
Powdered sugar	2 cups
Vanilla extract	1 tsp
Heavy cream (or milk)	2-3 tbsp

Optional Garnishes

• Crushed peanuts
• Mini peanut butter cups
• Chocolate drizzle
• Caramel drizzle

Equipment Needed

• Mixing bowls (for dry and wet ingredients)
• Electric mixer (for creaming butter and peanut butter)
• Cupcake liners and a muffin tin
• Measuring cups and spoons
• Spatula (for mixing and scraping the bowl)
• Piping bag with a frosting tip (for decorating)

Having an electric mixer is a game changer for achieving a light and fluffy batter, while a piping bag makes frosting application smoother and more professional-looking.

Step-by-Step Instructions

1. Preheat and Prepare

Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners to prevent sticking.

2. Mix the Dry Ingredients

In a bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures an even distribution of leavening agents for a consistent rise.

3. Cream the Butter, Peanut Butter, and Sugars

Using an electric mixer, beat the softened butter and peanut butter together until smooth. Add both sugars and continue beating until light and fluffy, about 2-3 minutes.

4. Add Eggs and Vanilla

Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.

5. Alternate Dry and Wet Ingredients

Add half of the dry ingredients to the wet mixture, followed by the milk and sour cream. Mix gently, then add the remaining dry ingredients. Stir until just combined—avoid overmixing to keep the cupcakes tender.

6. Fill the Cupcake Liners

Spoon the batter into the prepared liners, filling each about ⅔ full. This prevents overflow while allowing enough room for the cupcakes to rise.

7. Bake to Perfection

Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

8. Make the Peanut Butter Frosting

Beat the butter and peanut butter together until smooth. Gradually add the powdered sugar, mixing on low to prevent a sugar cloud. Stir in the vanilla, then add heavy cream one tablespoon at a time until the frosting reaches a fluffy consistency.

9. Decorate and Enjoy

Pipe or spread the frosting onto the cooled cupcakes. Garnish with crushed peanuts, mini peanut butter cups, or a drizzle of chocolate.

Tips and Variations

• Make it extra peanut buttery: Add ½ cup of peanut butter chips to the batter for bursts of peanut flavor.
• Chocolate twist: Replace ¼ cup of flour with cocoa powder for a peanut butter-chocolate cupcake variation.
• Nut-free option: Use sunflower seed butter as a peanut-free alternative.
• Healthier swaps: Replace half of the all-purpose flour with whole wheat flour and use honey instead of granulated sugar for a more wholesome treat.
• Vegan version: Substitute eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg), use dairy-free milk, and swap butter with vegan margarine.

Serving Suggestions

For a visually appealing presentation, pipe a swirl of frosting using a star tip and sprinkle chopped peanuts or mini peanut butter cups on top. A drizzle of melted chocolate or caramel enhances both the look and flavor.

Pair these cupcakes with a side of vanilla ice cream or a tall glass of cold milk for the ultimate indulgence. If serving at a party, arrange them on a tiered cupcake stand with decorative liners for an elegant display.

Pairings

Drinks That Complement Peanut Butter Cupcakes

• Milk: The classic peanut butter and milk combo never fails.
• Iced Coffee or Cold Brew: The slight bitterness of coffee balances the sweetness of the cupcakes.
• Peanut Butter Milkshake: Double down on the peanut butter goodness!
• Chocolate Stout Beer: For an adult pairing, a rich chocolate stout enhances the nutty notes.
• Hot Chocolate: Especially during winter, a mug of thick, creamy hot chocolate with these cupcakes is pure bliss.

Storage and Reheating

Refrigeration

Store leftover cupcakes in an airtight container at room temperature for 2 days or in the refrigerator for up to 5 days.

Freezing

Unfrosted cupcakes freeze well for up to 3 months. Wrap them individually in plastic wrap, then store them in a freezer-safe bag. Thaw at room temperature before frosting.

Reheating

To enjoy them warm, microwave an unfrosted cupcake for 10-15 seconds for a fresh-from-the-oven feel.
