Ingredients

• 1 cup creamy peanut butter
• ½ cup light butter or margarine, softened
• 1 cup light brown sugar, packed
• ½ cup granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• 1 ¾ cups all-purpose flour
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp salt
• 1 cup low-fat milk (or unsweetened almond milk)
• ¾ cup mini M&Ms (plus a few extra for topping)

Instructions

1. Preheat Oven & Prepare Pan
Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line with parchment paper.

2. Cream the Butter & Peanut Butter
In a large bowl, beat together peanut butter, butter, brown sugar, and granulated sugar until smooth and fluffy.

3. Add Eggs & Vanilla
Mix in eggs and vanilla extract until fully combined.

4. Combine Dry Ingredients
In another bowl, whisk flour, baking powder, baking soda, and salt. Gradually add to the peanut butter mixture, alternating with milk, beginning and ending with dry ingredients. Mix until just combined.

5. Add M&Ms
Fold in mini M&Ms, reserving a handful for the top.

6. Bake
Spread batter evenly in prepared pan. Sprinkle remaining M&Ms on top and gently press them in. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.

7. Cool & Serve
Allow cake to cool before slicing. Enjoy plain, with a dusting of powdered sugar, or topped with whipped cream.
