Ingredients
½ cup butter, softened
⅓ cup smooth peanut butter
½ cup granulated sugar
½ cup brown sugar
1 tsp vanilla extract
1 large egg
1 large egg yolk
1½ cups all-purpose flour
1 cup quick-cook oats
1 tsp baking soda
1 cup mini white chocolate chips
1 cup holiday M&M’s
2 tbsp holiday sprinkles
Instructions
-
Prepare pan: Preheat oven to 350°F (177°C). Line a 9×13-inch pan with parchment paper with overhang for easy removal. Lightly spray parchment.
-
Mix wet ingredients: Beat butter, peanut butter, granulated sugar, and brown sugar until light and fluffy.
-
Add eggs and vanilla: Mix in vanilla, egg, and egg yolk until combined.
-
Incorporate dry ingredients: Stir in flour, baking soda, and oats until well mixed.
-
Add mix-ins: Fold in white chocolate chips, ¾ cup M&M’s, and half the sprinkles.
-
Assemble bars: Press dough evenly into the prepared pan, filling corners. Top with remaining M&M’s and sprinkles, pressing lightly to adhere.
-
Bake and cool: Bake 15 minutes or until edges are lightly browned. Cool at least 30 minutes before slicing.
Notes
Use parchment paper with overhang for neat removal and clean squares.
Avoid overbaking to keep bars soft and chewy.
Quick oats provide tender chew without hardness.
Chill dough briefly if too soft to press well.
Press toppings firmly for festive presentation.
