Ingredients
  

For the Cupcakes
  • 1.5 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/3 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup buttermilk (or milk with a teaspoon of vinegar) Use buttermilk for best results.
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 2 tsp vanilla extract
  • 1 cup boiling water This will thin the batter.
For the Peanut Butter Frosting
  • 1 cup creamy peanut butter
  • 1 cup powdered sugar
  • 1/2 cup unsalted butter, softened
  • 1 tsp vanilla extract
  • 2-4 tbsp milk Add as needed for consistency.

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
  2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until fully combined.
  3. In another bowl, combine buttermilk, vegetable oil, eggs, and vanilla extract. Mix well.
  4. Pour the wet ingredients into the dry mixture and mix until just combined. Carefully stir in the boiling water. The batter will be thin, but that’s normal!
Baking
  1. Divide the batter evenly among the cupcake liners, filling each about halfway.
  2. Bake for 18-20 minutes or until a toothpick inserted into the center comes out clean.
  3. Allow the cupcakes to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Frosting
  1. In a mixing bowl, combine peanut butter, softened butter, and vanilla.
  2. Gradually add powdered sugar, alternating with milk as needed to reach your desired consistency.
  3. Once cupcakes are completely cool, generously frost each cupcake with the peanut butter frosting.
