Slow Cooker Hot Fudge Sundae Cake Made this for my sisters birthday and it came out delish! I made a double batch since my crock pot is bigger than the recipe called for, and I believe it was completely cooked in 2 hours. Next time I will try picking the cake up with 2 forks or 2 spatula's to put onto a platter OR just cutting the cake in half making it all the easier in removing from the crock pot, onto a plate, then just pouring the sauce over the cake and seams where you cut. But yesterday I just scooped out potions for everyone and people still ohhh'd and awhhhh'd !!! Will definately make again.
