If you can cook/bake an ice cream cake in the SRG or TBE..you can do it in the pellet pooper. It is just a big oven with smoke. You can add an amaznsmoke thingi for smoke. I have a 6" one that fits in everything. I would use a lighter wood, like a fruit wood or mild pecan wood. At 350º temp, I wouldn't preheat the cast iron too hot, but preheat if you want. Then cook as usual. I do a lot of outside cooking, so hope this helps some. The timing is the same, if a toothpick comes out clean. It's done. Good Luck. Pam .☆´¯`•.¸¸. ི♥ྀ
