Made this 2/24. Perfect Friday night dessert! So easy: Grease a ramekin with butter, dust with cocoa powder. Melt 1/4 c choc chips with 1 T butter in the microwave. Add 1 T pb, 1 egg, pinch salt and 1 tsp flour. Stir. Pour into ramekin and bake at 375 for 7-10 minutes. This was awesome! Perfect portion, everything was from the pantry. Loved it and will do it again and again. Maybe next time raspberry jam instead of the pb.
