Peanut Butter Brownies

Officially in the third trimester this week and I am hungry all. the. time.

I mean, I’ve always been up for eating, and my sweet tooth has always been pretty demanding, but things are getting a little out of control here. I made two pans of these peanut butter brownies last week and am embarrassed to tell you how much I devoured on my own. It’s not safe to keep sweets in the house anymore, especially not peanut butter and chocolate ones like these peanut butter brownies (also not safe: this Buckeye recipe!).

These peanut butter brownies were originally shared on the blog a few years ago but desperately needed a photo refresh.

They’re a peanut butter & chocolate lover’s dream, chewy and chocolatey, fudgy brownies rippled with creamy peanut butter blondies, packed with mini chocolate chips and Reese’s Pieces. They pretty much melt in your mouth and oh my goodness I’m almost drooling here.

How to Make Peanut Butter Brownies

1. Make your brownie batter first. This can all be made in a single bowl, and letting the batter sit while you prepare your peanut butter layer helps encourage shiny, crackly brownie tops (which we all love).
2. Prepare your peanut butter layer! I recommend using an electric mixer as you’ll need to cream together the butter and sugar. This batter gets a bit stiff until you add the milk (at the very end), but don’t worry, everything will come together.
3. Dollop away! Peanut butter, chocolate, peanut butter, chocolate. Alternate dropping spoonfuls of brownie batter and peanut butter batter into a 13×9 pan. It’ll start out looking like a patchwork quilt, then use your knife to swirl everything together. You want to have some peanut butter and some chocolate in every bite.

All in all you will need three bowls total to make these peanut butter brownies, but the dishes are worth it.

Ok, I think that’s all for today because if I write another word about peanut butter brownies I’m going to find myself up to my elbows in batter in a few minutes and then regretfully googling the effects of excessive peanut butter and chocolate consumption on unborn children.

Enjoy (and Happy Labor Day!)!
