M&M Oreo Brownies
These easy dessert bars start with a boxed brownie mix and get a fun upgrade with chopped Oreos and M&Ms. Perfect for potlucks, birthdays, and any time you need easy party desserts fast.
Equipment
- 1 9x13 pan
Ingredients
- 1 box brownie mix Any brand you like. I prefer fudgy brownies that specify on the box that they work for a 9x13 pan
- Eggs, oil, and water as called for on the box for your brownie mix
- 12-15 Oreos roughly chopped
- 1 cup M&Ms plus some extra to sprinkle on top
Instructions
- Start by preheating your oven to the temperature listed on your brownie mix box. Spray a 9x13-inch pan with cooking spray or line it with parchment paper for easy removal.
- In a large bowl, prepare your brownie batter according to the instructions on the box. You can use whatever mix you prefer, but if you're using a 9x13 pan, just make sure the instructions include baking times for a 9x13 pan.
- Gently fold in most of the chopped Oreos and M&Ms, but save a decent amount to sprinkle on top later for a fun, festive pop.
- Pour the batter into the prepared pan and smooth the top. Pour the batter into the prepared pan and smooth the top.
- Bake for about 15 minutes, or for about ¾ of the time your box mix tells you to. For me, it said 24 minutes, so that was around 18 minutes.
- Remove the pan from the oven and sprinkle the reserved Oreos and M&Ms into the top of the brownies.
- Put your brownies back in the oven to finish baking. You know they're done when you stick in a toothpick in the middle and it comes out with a couple crumbs (but not dripping in raw batter).
- Let the brownies cool completely in the pan before cutting them into squares. For the cleanest slices, chill the brownies in the fridge for about 30 minutes before cutting.
