I would NOT use Bob’s Biscuit and Baking Mix in this. That mix is intended for pancakes, waffles and biscuits and contains other ingredients than just “flour.” You could use Bob’s Red Mill 1 to 1 Baking Flour (blue bag) for this recipe.

They are similar to chocolate chips. They can be left out if you like.

Dear Caroline, I always recommend finding recipes written with the ingredients you can use. If you’re looking for a grain free apple bundt cake, I would recommend this one by Nom Nom Paleo. https://nomnompaleo.com/apple-bundt-cake-paleo-gluten-free

Dear Audrey, you can use King Arthur. Cake batter is more forgiving with different flours than other pastries.

This recipe is a small batch cake recipe. It was originally made in a 6″ fluted pan. The batter would only fill one 6″ round pan. I imagine you would bake it for the same amount of time.
