– 2 & 2/3 cups (320g) all-purpose flour – 1 & 1/4 teaspoons baking powder – 1/2 teaspoon salt – 1 cup (226g) unsalted butter, softened – 1 cup (200g) granulated sugar – 1/3 cup (67g) firmly packed light brown sugar – 2 large eggs – 1 egg yolk – 2 teaspoons vanilla extract – about 1 cup M&Ms – 1 & 1/4 cups (160g) marshmallow creme

Preheat oven to 350°F. Parchment a 9" x 13" x 2" baking pan. Lightly grease the paper and pan interior. Mix flour, baking powder, and salt. Set aside.

Step 1 


Beat butter, sugar, and brown sugar until fluffy with a medium-speed electric mixer. After adding each egg and egg yolk, mix well. Mix in vanilla.

Step 2

Slow down the mixer. Add flour mixture slowly, mixing just until combined. Reserve a cup of dough for topping.

Step 3

Evenly distribute cookie dough in the pan. Sprinkle half the M&Ms on the dough and lightly press them in.

Step 4

Next, add marshmallow creme to the dough. Finally, scatter small amounts of reserved dough on top.

Step 5

Bake the bars for 25–30 minutes until golden brown and a pick inserted into the center comes out clean.

Step 6

Let the cookie bars cool for 5 minutes on a wire rack. Sprinkle the remaining M&Ms on the bars and gently press them in.

Step 7

Top with sprinkles. Lift the bars from the pan and cut them after they cool completely.
