Making the Irresistible Peanut Butter M&M’s Cake is easy if you follow these steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Cream Peanut Butter and Sugars: In a large mixing bowl, beat together the peanut butter, granulated sugar, and brown sugar until smooth and creamy.
4. Add Eggs and Vanilla: Incorporate the eggs one at a time into the mixture, followed by the vanilla extract, mixing well after each addition.
5. Combine Wet and Dry: Gradually add the dry ingredients to the peanut butter mixture, alternating with the milk. Start and end with the dry ingredients. Mix until just combined.
6. Fold in M&M’s: Gently fold in the M&M’s, reserving a handful to sprinkle on top.
7. Divide Batter: Pour the batter equally into the prepared cake pans.
8. Bake: Place in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool the Cakes: Once done, 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.
10. Frosting (Optional): Frost the top of one cake layer with chocolate frosting, place the second layer on top, and frost the top and sides as desired.
11. Garnish: For an extra pop, sprinkle additional M&M’s on top of the frosted cake.
