Ingredients

For the Cake:

1 ½ cups all-purpose flour (190 g)

1 cup granulated sugar (200 g)

½ cup packed brown sugar (100 g)

¾ cup unsweetened cocoa powder (75 g)

1 teaspoon baking soda

½ teaspoon baking powder

½ teaspoon salt

½ cup creamy peanut butter (125 g)

¾ cup vegetable oil (180 ml)

½ cup milk (120 ml)

2 large eggs

2 teaspoons vanilla extract

1 cup M&M’s (170 g)

For the Frosting:

1 cup creamy peanut butter (250 g)

4 cups powdered sugar (460 g)

½ cup unsalted butter, softened (115 g)

¼ cup milk (60 ml)

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.

  2. Mix the dry ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, cocoa powder, baking soda, baking powder, and salt.

  3. Prepare the wet ingredients: In a separate bowl, combine peanut butter, vegetable oil, milk, eggs, and vanilla extract. Mix until smooth.

  4. Combine wet and dry ingredients: Gradually add the wet ingredients to the dry ingredients and mix until fully combined.

  5. Add the M&M’s: Gently fold in the M&M’s, reserving a few for decoration.

  6. Bake the cakes: Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

  7. Cool the cakes: Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.

For the Frosting:

  1. Make the frosting: In a large bowl, beat together the creamy peanut butter, softened unsalted butter, and powdered sugar until smooth and creamy.

  2. Adjust consistency: Gradually add milk until the frosting reaches your desired consistency.

Assembling the Cake:

  1. Frost the cake: Once the cakes have cooled completely, spread a layer of frosting on top of one cake layer.

  2. Stack the layers: Place the second cake layer on top and frost the top and sides of the entire cake.

  3. Decorate: Decorate the top of the cake with the reserved M&M’s for a fun and colorful touch.

Notes

Flour measurement: For accuracy, spoon the flour into the measuring cup and level it off to avoid a dense cake.

Storing the cake: Store leftovers in an airtight container at room temperature for up to 3 days.
