I have been having the hardest time with my brownie recipe lately. I've made brownies before that have turned out great, but as of lately, my brownies have been awful. They won't finish cooking, all of the sugar rises to the top and all of the butter sinks to the bottom. Its an absolute mess and I can't think of why they are doing this. I am making them from scratch and am following the direction to a T (though instead of eggs I use an egg replacer, but I always bake with this). I'm using a glass pan with mint chips and chocolate chips in the mixture. Can anyone help me with this issue.... I hate spending so much time making these things just for them to be grainy/oily and raw after 20 min in the oven.
