Texas Peanut Butter Sheet Cake: This was good. I'll make it again. I didn't have a pan the size they recommended, so I put it in a 9x13. That said, there was barely enough frosting, so if I did the jelly roll I'd definitely make more frosting. Loved crunchy PB in the frosting.
Best-Ever Chocolate Nutella Layer Cake - This turned out really well. LOVED the frosting. Cake needs to be mixed more thoroughly than what this recipe says. Baked 3 8-in rounds which took a lot longer than the recipe claimed. I advise flour pans as well.
