Creating the Irresistible Peanut Butter M&M’s Cake goes smoothly if you follow these straightforward steps:

1. Preheat Oven: Set your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a mixing bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt.

3. Cream Butter and Peanut Butter: In a separate bowl, beat together the softened butter and peanut butter until creamy.

4. Add Sugar: Gradually add the granulated sugar to the peanut butter mixture, beating until light and fluffy.

5. Incorporate Eggs: Add the eggs one at a time, mixing well after each addition.

6. Blend in Milk and Vanilla: Pour in the milk and vanilla extract, mixing until combined.

7. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.

8. Fold in M&M’s: Gently fold in the M&M’s, reserving a handful for decoration.

9. Distribute Batter: Divide the batter evenly between the two prepared cake pans.

10. Bake: Place the pans in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

11. Cool Cakes: Once baked, remove the cakes from the oven and let them cool in the pans for about 20 minutes. Then, transfer them to wire racks to cool completely.

12. Prepare Frosting: In a medium bowl, blend the peanut butter, powdered sugar, heavy cream, and vanilla extract until smooth and creamy.

13. Assemble the Cake: Once the cakes are completely cooled, place one layer on a serving platter. Spread a layer of frosting on top.

14. Stack Layers: Place the second cake layer on top of the frosted layer. Use the remaining frosting to cover the entire cake.

15. Decorate: Top the cake with the reserved M&M’s, arranging them as desired.

Following these steps will ensure that your Irresistible Peanut Butter M&M’s Cake turns out incredible and ready for enjoyment!
