Choc-O-PB Bars: Chocolate Oreo Peanut Butter

Warning: These bars are rich, addicting, gooey, and dangerous. Once you start eating them, it’s very hard to stop.

Add Oreos to fudgy brownies, and then add a gooey peanut butter oat layer choc-full of peanut butter cups, and you get these:

Chocolate. Peanut butter. Oreos. Peanut butter cups. Personally, these are all of the best things. My favorite flavors, combined into one bangin’ bar.

These came out pretty thick. Next time I’d actually make them half as thick and they’d cook a smidge better and more evenly. Don’t get me wrong– these came out SO GOOD. The recipe below will turn out just like these. If you want to the bars to be a bit more of a “manageable” thickness, just cut the recipe in half and still bake it in a 13×9 inch pan, but for only about 35 minutes instead of an hour.

I’m hungry. You? 🙂

Brownie layer:
2 sticks unsalted butter (1 cup), melted
2 Tablespoons oil (I use canola oil)
1 cup light brown sugar
1 cup granulated sugar
1 tsp salt
2 tsp vanilla extract
4 eggs
1 cup unsweetened cocoa powder, sifted
1 cup flour
1 tsp baking powder
about 20 cookies n cream cookies, i.e. Oreos, Trader Joe’s Joe Joe’s, etc

Peanut butter layer:
1 1/2 sticks (3/4 cup) butter, melted
1/2 cup peanut butter, heated in the microwave for 15 seconds
1/2 cup granulated sugar
1 cup brown sugar
2 eggs
1/2 teaspoon vanilla extract
1/2 teaspoon salt
1 1/2 tsp baking soda
1 1/2 cup flour
2 cups rolled oats
about 2 cups chopped peanut butter cups

1/4 cup chocolate chips
1/4 cup peanut butter

1) Line a 13×9 inch pan with foil. Spray the foil with non-stick cooking spray. Set that aside.
2) In a large bowl, whisk together your melted butter, 2 Tablespoons of oil, granulated sugar, brown sugar, and salt. Whisk whisk whisk until the mixture if fully combined and your arm is tired. 😉
3) Add in the vanilla extract and eggs and whisk again. You want the eggs to be fully whisked in, without totally killin’ ’em. In other words, when you have a homogeneous mixture, you’re good.
4) You could sift together your dry ingredients into a different bowl and then add them to the wet ingredients; however, I like to do this all in one bowl. Easier, fewer steps, less mess. So, into the butter mixture, sift in the cocoa powder. Whisk these in until they’re mostly combined. After that, you’re done with the whisk.
5) Sift in the flour and baking powder. Once you sift them in, they’ll be sitting on top of the batter. Mix them together with a rubber spatula, and then continue to gently mix all of the flour and baking powder into the butter-egg-chocolate mixture. Your end result will be a beautiful, deeply chocolaty brownie batter.
6) Lastly, fold in the Oreos. I chop the Oreos roughly into quarters and then add them in.
7) Spread the batter into your prepared baking pan.
8) Now the peanut butter layer! At this point, I’d preheat the oven to 325 degrees F.
9) In that same brownie bowl, add the melted butter, granulated sugar, brown sugar, and peanut butter. Whisk whisk these together until smoooth and creamy. Add in the salt, vanilla extract, and eggs, and whisk again until everything is fully combined.
10) Switch to a rubber spatula and stir in the flour, oats, and baking soda. keep mixing until you have a thick peanut butter dough. Add in the chopped peanut butter cups.
11) Spread the peanut butter batter on top of the brownie batter.

For me, these two combined filled to the top of my 13×9 inch pan. Chyeah– they’re t-h-i-c-k!

12) Bake the bars in the 325 degrees oven for about 1 hour, or until the top is golden brown.
13) Cool the bars in the pan until they’re completely cooled. Then, the final step– the drizzle! Melt the chocolate chips in a bowl in the microwave for 45 seconds, stirring every 15 seconds. Using a fork, drizzle the chocolate over the bars.
14) Then, in that same chocolate chip bowl, melt the peanut butter for just about 15 seconds– it won’t take much to make it melty. Use that fork to drizzle the peanut butter over the bars too. Top with additional chopped oreos and peanut butter cups.

15) Cut the bars, and serve ’em!

Chocolate and peanut butter is simply the best, don’t you think? If yes, what else do you like that’s choc & pb?! If no, what’s your favorite combo?

Happy baking!
