- 1½ cups all-purpose flour
- ¾ teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsweetened cocoa
- ¾ teaspoon instant coffee (optional)
- ½ cup boiling water
- ⅓ cup sour cream
- ¾ teaspoon vanilla extract
- 12 tablespoons butter, softened
- 1½ cups sugar
- 3 large eggs, at room temperature
- ¼ cup peanut butter
- 1 container (1 pound) store-bought chocolate frosting
- 3 peanut butter cups, quartered
- Adjust oven rack to lower-middle position and heat oven to 400 degrees. Line a 12-cup muffin tin with cupcake papers; spray with vegetable cooking spray.
- Whisk flour, baking soda, and salt in a medium bowl; set aside. Measure cocoa and coffee in a medium bowl. Whisk in water to form a smooth thick paste. Stir in sour cream and vanilla; set aside.
- With a hand mixer, beat butter and sugar until light and fluffy. Beat in eggs, one at a time. Starting and ending with dry ingredients, alternate adding chocolate mixture and flour, beating until each is thoroughly incorporated.
- Evenly divide batter among prepared muffin cups. Bake until fully cooked and golden, about 20 minutes. Remove from oven, let cupcakes stand a couple of minutes; turn onto a wire rack to cool.
- Meanwhile, whisk peanut butter into frosting; spread a portion over each cupcake. Garnish with peanut butter cup quarters. Serve.
