Bubbles in baked gingerbread pieces.
I used a silicon mold for my very first attempt at gingerbread. Everything went well until I took it out of the oven and 3 pieces were bubbled up so that the outside of the pieces looked like the house had been bombed! What caused the gingerbread to bubble up during bak8ng? Thanks. I checked the questions but did not see where this one had been answered.
