- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 5 tablespoons peanut butter (smooth)
- 4 tablespoons vegetable oil
- 1/2 cup brown sugar (packed)
- 2 eggs (room temperature)
- 1 teaspoon pure vanilla extract
- 1/2 cup buttermilk (room temperature)
Peanut Butter Buttercream
- 2 sticks unsalted butter (room temperature)
- 1/2 cup vegetable shortening (room temperature)
- 1 1/2 cup peanut butter (smooth)
- 4–6 cups powdered sugar
- 1 teaspoon pure vanilla extract
- 1/2 cup dark chocolate unsweetened cocoa powder (optional)
Garnish
- 12 Peanut Butter Cups
Instructions
- Preheat: Preheat the oven to 350º F. Position the oven rack in the middle for even baking.
- Line: Line a regular muffin tin with 12 cupcake liners and set it aside.
- Mix Dry Ingredients: In a medium mixing bowl, whisk together cocoa powder, sifted flour, baking powder, baking soda, and salt until fully combined. Set aside.
- Beat Wet Ingredients: In a large mixing bowl or electric mixer fitted with a whisk attachment, beat peanut butter, vegetable oil, and brown sugar until the mixture is smooth and fluffy.
- Incorporate Eggs & Vanilla: Add eggs one at a time along with vanilla extract, mixing on medium speed until fully combined. Pause periodically to scrape the bowl sides and bottom to ensure even mixing.
- Combine Wet & Dry: Alternately add the dry flour mixture and buttermilk by hand, mixing gently to avoid overmixing, until all ingredients are just combined.
- Fill Liners: Fill each cupcake liner nearly full with the batter to allow room for rising.
- Bake: Bake for 15-17 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs.
- Cool in Pan: Let the cupcakes cool in the pan for 3 minutes before transferring.
- Transfer to Rack: Carefully remove cupcakes and place them upside down on a cooling rack to form dome-shaped tops. Allow them to cool completely before frosting.
- Prepare Buttercream: In a large mixing bowl or stand mixer, beat the butter and vegetable shortening until fluffy using a whisk attachment.
- Add Peanut Butter & Vanilla: Beat in the peanut butter and vanilla extract on medium-high speed until fully combined, scraping the bowl as necessary.
- Add Powdered Sugar: Gradually add powdered sugar one cup at a time, starting at low speed then increasing to medium, until the frosting is stiff and sweet to taste (approximately 4 cups used).
- Optional Chocolate Buttercream: Transfer half of the buttercream to another bowl and mix in 1/4 cup of cocoa powder using a mixer for chocolate variation.
- Fill Piping Bag: Fill a piping bag fitted with a large star tip with either peanut butter buttercream alone or with both peanut butter and chocolate buttercream side-by-side for a marbled effect.
- Pipe Frosting: Starting at the center of each cupcake, pipe the buttercream in a swirl outward and then back to the center, layering to create a decorative dome.
- Garnish: Top each cupcake with one peanut butter cup as garnish.
- Chill: Refrigerate cupcakes for at least 2 hours to set the frosting before serving. Enjoy!
Notes
- Room temperature ingredients ensure smoother batter and creamier frosting.
- Sifting dry ingredients helps avoid lumps and promotes even distribution.
- Filling cupcake liners almost full gives nicely domed cupcakes after baking.
- Scraping the bowl during mixing prevents uneven texture and helps full incorporation.
- Allowing cupcakes to cool completely before frosting prevents melting or sliding of buttercream.
- Chilling after frosting helps the cupcakes hold their shape during serving.
- Optional cocoa powder in buttercream adds a rich chocolate twist if desired.
