These soft, chewy bars are filled with M&Ms, white chocolate chips, and rolled oats. Made in under 30 minutes, add these festive cookies in bar form to your Fourth of July celebration.
0 Preheat oven to 350°F / 177°C. Line an 8x8 metal baking pan with parchment paper and / or spray the pan with nonstick cooking spray.
1 In a medium mixing bowl, whisk together the flour, baking powder, and salt. Set aside.
2 In a larger mixing bowl, whisk together melted butter and brown sugar until evenly combined. Whisk in egg and vanilla.
3 Pour dry ingredients over wet and stir with a spatula or wooden spoon just until no dry spots remain (do not overmix.)
4 Gently stir in oats, M&Ms, and white chocolate chips.
5 Pour batter into prepared pan, scattering any reserved mix-ins over top.
6 Bake 24 to 28 minutes, until the edges are lightly browned. (Note: If cooked on the lower end of the bake time, these will be very soft and will stay moist for a couple of days. If you plan to serve them the same day as they were baked, bake at the higher end of the recommended cook time.)
7 Let cool in the pan until the bars can be easily removed. Once cool, slice and serve.
8 The bars can be stored at room temperature for up to 3 days.
