~yields 9-12 brownies (1 9x9inch pan)
The Bits and Bobs:
1 cup unsalted butter, melted
2 cups brown sugar
2 whole eggs
2 egg yolks
2 tbsp molasses
2 tsp vanilla extract
2 tsp instant espresso powder
1/4 tsp salt
1 1/2 cup all purpose flour
1/2 cup unsweetened cocoa powder
10 oz peanut butter chips
Preheat oven to 350*F. Grease a 9x9-inch brownie pan and set aside
In a large bowl, mix together the melted butter and the brown sugar until well combined and smooth. Mix in the eggs and egg yolks, the molasses, vanilla, and espresso powder until just incorporated.
Stir in the flour, the cocoa powder, and the salt until combined. Mix in half of the peanut butter chips into the batter.
Pour the batter into the prepared pan and then sprinkle the remaining peanut butter chips over the top.
Bake for 25-30 minutes, turning the pan once halfway through bake time. The edges should be set and pulling away from the pan and the center should be set. A toothpick inserted in the middle will come out with slightly dirty, but not with goopy batter.
