I love brownies…especially thick, fudge-y brownies with lots of extra chocolate flavor. And adding peanut butter…ALL the yes to that!!

Baking with Espresso Powder – Explained
This recipe was originally named “espresso brownies,” but I decided to change the name because they don’t actually taste like coffee.
So why add espresso powder to brownie mix at all?
Adding espresso or coffee while baking is a little trick that brings out BIG chocolate flavor. Adding coffee powder to cake mix is a sneaky (but delicious) way that pro bakers enhance chocolate flavor in their desserts.
You’ve got to taste it to believe it!

How to Make Chocolate and Peanut Butter Brownies
A free printable copy of the full recipe is below the prep tips.
While oven preheats, prepare an 8×8-baking pan with non-stick baking spray.
TIP: Lining the pan with foil and spraying the foil will allow for easy removal.
Combine oil, water, egg and espresso powder in a large mixing bowl. Stir in the brownie mix until it’s well combined. Gently stir in ¾ cup of the peanut butter chips.
Pour the batter into baking pan. Scatter the remaining peanut butter chips on top and finish with a sprinkle of sea salt.
Bake 35-40 minutes or until a toothpick comes out clean. Allow the brownies to cool completely before cutting.
To make a chocolate drizzle:
Using a microwave safe bowl, heat chocolate chips in 20 second intervals, stirring in between, until melted. Use a spoon or fork to drizzle melted chocolate on top of your chocolate peanut butter brownies.
Lastly, try not to eat the whole pan!
Oh wait, that’s just me…
