You can easily make JoJo's Carrot Cake dairy or nut free or both! For the cake, exclude nuts from the batter. For the frosting, use a plant based butter and cream cheese. I've not tried making a gluten free version, but I'd be willing to bet gluten free 1:1 baking flour would work (using ~2-3 less tablespoons of flour since GF flour is slightly drier).
