Storage: Store this Gluten-Free Apple Coffee Cake in an airtight container or covered at room temperature for up to 1 day. Or store in an airtight container in the refrigerator for up to 4 days. To freeze, cut into individual servings and freeze in an airtight refrigerator-friendly container for up to 6 months.

Note: I used some white sugar for the streusel when I ran out of coconut sugar for the photo, but recommend using all coconut sugar or brown sugar.


  • Gluten-Free 1-to-1 Flour - instead of cassava flour, you can use gluten-free 1-to-1 flour. I tested this recipe with both and there was no difference in texture or flavor. I used Bob’s Red Mill 1-to-1 Gluten-Free Flour and Otto’s Cassava Flour.
  • Brown Sugar - if you don’t have coconut sugar, brown sugar works well too.
  • Paleo - this recipe is paleo as written. You must use coconut sugar and cassava flour for it to qualify as a Paleo coffee cake.


  • Peach Coffee Cake - replace the sliced apples with sliced peaches
  • Plum Coffee Cake - replace the sliced apples with sliced plums
  • Strawberry Rhubarb Coffee Cake - see the exact measurements of strawberry to rhubarb needed for this recipe in my Gluten-Free Rhubarb Cake recipe on this website
