  • 1 cup butter, room temperature
  • 1 cup sugar
  • 1 tsp vanilla extract
  • 3 eggs
  • 1 cup vanilla yogurt, drained
  • 2 cups all-purpose flour
  • 2 tsp baking powder
  • A pinch of salt
  • 3/4 cup Peanut Butter M&M’S, roughly chopped


  • 1 cup butter, room temperature
  • 2 cups creamy peanut butter
  • 5 cups powdered sugar
  • 1/4 cup heavy cream (optional)


  1. Prep and Bake Cake: Preheat oven to 350°F (177°C). Grease and line two 9-inch round baking pans. Cream together butter and sugar until light and fluffy. Add vanilla, then eggs one at a time, mixing well after each addition. Mix in drained yogurt. Gradually add flour, baking powder, and salt. Fold in chopped M&M’S and divide the batter between prepared pans. Bake for 22-25 minutes or until a toothpick inserted into the center comes out clean. Cool completely.
  2. Make Frosting: Beat butter and peanut butter until smooth. Gradually add powdered sugar. If desired, add heavy cream and whip until fluffy.
  3. Assemble Cake: Place one cake layer on a serving platter. Spread half of the frosting over the first layer, then top with the second layer. Cover the top and sides with the remaining frosting. Decorate with additional M&M’S.
  4. Chill: Refrigerate the cake for 2-3 hours before serving to set the frosting.


  • Drain the yogurt in a cheesecloth or fine mesh sieve for a few hours in the fridge to remove excess moisture, ensuring a denser, more stable cake.
  • Skip the heavy cream in the frosting for a sturdier texture unless using a cake ring.
  • Decorate with a mix of Peanut and Peanut Butter M&M’S for extra flair and texture.


Q: Can I use regular M&M’S instead of Peanut Butter M&M’S in the cake?
A: Yes, regular M&M’S can be used, but Peanut Butter M&M’S enhance the peanut butter flavor of the cake.

Q: How should I store this cake?
A: Store the cake in the refrigerator due to the frosting. It’s best enjoyed within 3-4 days.
