Servings 12 bars
Ingredients
- 1/2 cup salted butter (1 stick, 8 tbsp, or 113 grams)
- 1/3 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1 large egg
- 1 tsp vanilla extract
- 1 and 1/3 cups all-purpose flour
- 1/2 tsp baking soda
- 1/8 tsp salt
- 1/2 cup m&ms
- 1/2 cup white chocolate chips
- 1/2 cup chopped salted macadamia nuts Can omit nuts if needed
Instructions
- Prep: Line a 9x9 pan with parchment paper. Preheat your oven to 350 degrees F.
- Make the Bars: Melt the butter in a medium mixing bowl. Add sugars and whisk until well combined with the butter. Add the egg and vanilla and whisk until just combined. Stir in the dry ingredients, mixing until the dry streaks just disappear into the dough. Stir in the nuts, white chocolate chips, and m&ms.
- Bake: Add the dough to your prepared pan and evenly press it in. Top with an extra handful of each of the mix-ins. Bake for 18 to 20 minutes. The bars will look a bit underdone, and a toothpick inserted into the center will pull out some moist doughy crumbs. The bars will set up more as they cool.
- Serve + Store: Let bars cool at least 1 and 1/2 hours before slicing. Enjoy warm! Store leftovers in an airtight container at room temp for 3-4 days, or 4-6 days in the fridge.
