Can I Use Homemade Batters For These Brownie Bars?
If you don’t want to use a store bought boxed brownie and cookie mixes, you are more than welcome to make homemade. Just follow the same directions on mixing up the brownies. Then mix up a cookie monster cookie batter then top the brownies with.
How to Make
Brownie Batter – Start by working on mixing up your brownie batter. Then you will pour into your greased baking dish and bake for 15 minutes as directed. Then remove from oven.
Cookie Batter – While the brownies are cooking you are going to work on your cookie batter. Mix until the cookie dough is fully combined.
Assemble Bars – Now you will scoop the cookie dough on top of the brownie batter, then spread and bake as directed.
Cool and Serve – Let the brownie bars cool then slice and serve!
Storing Monster Cookie Brownies
Store your brownies in an airtight container once they are fully cooked. The bars will store for around 5 days at room temperature. You can also freeze your brownies for 2-4 months.
Just freeze and then thaw at room temperature on the counter.
Mix In Ingredients
Want to change up the bars a little bit? Here is a fun switch of ingredients to alter the end result of the brownies!
- Use a brownie mix with nuts or even a caramel swirled brownie for elevated flavor.
- Mix in some peanut butter chips along with chocolate chips or in replace.
- Use Reese’s Pieces instead of M&M’s
- Use a peanut M&M or peanut butter M&M for a switch to the candy topping.
Why Do You Cook Brownies A Bit Before Cooking Cookie Layer?
You need to cook the brownies a bit to ensure the brownie layer bakes fully. Also, baking the brownies helps to keep the cookie layer on top of the brownies, vs sinking to the bottom of the brownies, and not creating that unique layered brownie.
