The Brownie Bar
As with all of my recipes, this brownie bar recipe is full of flavor AND simple. And, if all you want is a fantastic brownie, just make this step. But, I’m feeling extra today so we’re gonna add a couple of layers!
First, melt the butter and baking chocolate on low heat in a small saucepan (or slowly in the microwave) until you have a smooth chocolate mixture. Add this to a large mixing bowl.
Next, add the sugar to the mixing bowl and combine. Then mix in the eggs and vanilla to combine. Fold in the flour and chocolate chips and you have a brownie mix fit for a queen.
Throw this in a preheated 350° oven, in a 9×13 parchment lined baking pan, for about 25-30 minutes. Test it with a toothpick and make sure the toothpick comes away clean after removing from the oven.
Now, on to the next step of our brownie bar adventure!
The Peanut Butter Layer
Not that the brownie layer isn’t enough, but why in the world would we stop there? We just gotta add a maple peanut butter layer to our peanut butter brownie bars! We must!
This step is super easy, so don’t be intimidated. To a microwave safe measuring cup, add the peanut butter, maple syrup, and avocado oil. Heat in the microwave on low, in 30 second increments. The idea here is to just warm and combine everything so that it’s spreadable. No need to cook it until it bubbles.
Once the mixture is completely combined, pour over the brownie layer. Using an offset spatula, smooth the peanut butter mixture evenly over the brownie layer.
Now, we have our second layer of the Salted Chocolate Peanut Butter Brownie bars complete. Put this in the fridge to cool off for about 30 minutes or so before we move on to step 3!
The Salted Chocolate Top Layer
One more layer until you can enjoy to most decadent Chocolate Peanut Butter Bar you’ve ever had. And, once again, no worries. This step is super simple!
Grab that microwave safe measuring cup and add the chocolate chips and avocado oil. Again, into the microwave on low, 20-30 second increments until the chocolate is melted and the mixture smooth.
Pour the melted chocolate onto the cooled peanut butter brownie bars and spread. Sprinkle with flaky sea salt. Put the bars back into the fridge for the chocolate to set up just a bit.
Enjoy with a glass of cold milk or a piping hot cup of coffee!
