Deliciously Fudgy Skillet Brownie is a dense and rich and gooey decadent dessert you won't soon forget. It's shareable, an all-time favorite... perfect for Friday nights, weekend treats... and even special occasions like Valentine's Day.
Preheat the oven to 350 degrees and lightly coat a 10-inch oven-safe skillet. Set aside.
Melt the butter, chocolate chips, and unsweetened cocoa powder in a medium bowl set over simmering water. Let cool slightly before stirring in the oil, eggs, coffee granules and vanilla. Then add the flour, baking powder, and salt; mix until just incorporated. Pour the batter into the prepared skillet and spread into an even layer using a spatula.
Bake the skillet brownie until the surface appears set, a toothpick inserted into the center should come out mostly clean; 35 to 40 minutes. Let cool completely before cutting into wedges -- or serving family style with spoons!
