Peanut Butter Oreo Brownies Recipes

If there is one baking ingredient I recommend having on hand for quick desserts it is brownie mix.  Check out our round-up of recipes using a brownie mix for other great ideas. 

My daughter has spent a lot of time baking lately and comes up with ways to turn a box of regular brownie mix into something bakery worthy.

Peanut Butter Oreo Brownies Recipes

We have made peanut butter brownies before, but my daughter took these to a new level by adding more chocolate and Oreos to the batter. 

We also love these new baking pans that don’t stick. Check out the details below.

Other Quick Toppings for Brownies

For both variations just make the brownie per the recipe below. Add only 1/2 of the peanut butter cups to one side and place it back into the oven.

When the brownies cool for a few minutes add your Valentine Peppermint Patties. Love the heart shape so could not resist. Obviously you can use regular ones too. Even add them to half the batter.  

The peanut butter cups did not melt as much as the picture in the book so I helped that along by using an offset spatula and flattened them. Maybe I did not chop them small enough not sure.

 Now for the taste test: I arranged them next to each other on a platter and let people dig in. Make sure you make it ahead of time to allow for the chocolate to cool before stacking it on a platter.

 The votes were cast and surprisingly the kids all voted for the peppermint version and the adults the peanut butter. I actually liked the peppermint ones but my favorite ice cream is Mint Chocolate chip.
