Stuffed Peanut Butter Brownies
I couldn’t be friends with someone who didn’t love this combination for brownies! Or maybe I could? More for me!
Featuring a deep chocolate flavor thanks to the combination of dark brown sugar and unsweetened cocoa powder with a layer of silky peanut butter mashed in the center. Peanut butter and chocolate were made for this Heavenly Peanut Butter Stuffed Brownies!
The secret is to time it all out. It is fairly simple to follow, first you freeze the peanut butter. These are not made to be healthy and it works with a no-stir generic brand of peanut butter. You need to buy one that is thick, I use JIF, but use any that you like.
After it is frozen (about 1 hour), you start making the batter. Keep the peanut butter in the freezer until you are ready to assemble your layers. The cooling period is crucial here because you want the peanut butter to set up. Now, if you are like me you cannot wait so you dive right in! HA! My patience is only good for 4 hours.
These are great to serve any time of the year for any get together, family party, birthday’s, small gatherings, etc. Heck, I would even have these at my wedding if I ever got married….I mean who needs cake when you have these? BUT REALLY!
