A low-carb and keto coffee cake with cinnamon and star anise blended in with flax, almond, and coconut flour is so light and fluffy! Ready in 30 minutes.
Whisk eggs in a small bowl. Add butter and sour cream.
In a second bowl, mix all dry ingredients together. Reserve the nuts to be either blended into the batter or sprinkled on top.
Combine the dry ingredients with the egg mixture. If desired, blend the nuts in now. Pour batter into greased 8 by 8-inch glass baking dish. If the nuts are not blended in to the dough, sprinkle them on top now.
Bake for 30 minutes. Test the center with a knife. If it is ready, remove from the oven and let cool. Serve warm, room temperature or cold.
