Ingredients
1/2cupsalted butter(1 stick, 8 tbsp, or 113 grams)
1/3cupgranulated sugar
1/2cupbrown sugar, packed
1largeegg
1tspvanilla extract
1 and 1/3cupsall-purpose flour
1/2tspbaking soda
1/8tspsalt
1/2cupm&ms
1/2cupwhite chocolate chips
1/2 cupchopped salted macadamia nutsCan 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.
