Instructions

1. Preheat the Oven :

   • In a mixing bowl, whisk together the almond flour, coconut flour, sugar substitute, baking powder, baking soda, cinnamon, and salt until evenly combined.

Tips for Perfect Sweet Potato Honey Bun Cake

1. Use Fresh Sweet Potato : Freshly mashed sweet potato has a better texture than canned alternatives, but either works in a pinch.
2. Don’t Overmix the Batter : Overmixing can make the cake dense. Stir just until the ingredients are combined.
3. Test for Doneness : Insert a toothpick into the center of the cake. If it comes out mostly clean with a few crumbs, it’s ready.
4. Store Properly : Keep leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for longer shelf life. Freeze slices for up to 3 months.
