Commonly Asked Questions
Can I use a different flour instead of almond flour?
Almond flour gives this cake its moist, tender texture, but if you need a substitute, try oat flour or a mix of oat and all-purpose. Just note the texture may change slightly and it might not be as soft.
What does kefir do in this recipe?
Kefir adds moisture and a subtle tang, similar to buttermilk or yogurt. It also helps activate the baking soda and gives the cake a really nice, fluffy rise.

Can I skip the espresso powder?
Yes, it’s totally optional. It won’t make the cake taste like coffee! It just deepens the banana and chocolate flavors if you’re adding chips.
How do I know when the cake is done?
Check it with a toothpick near the center. It should come out mostly clean with a few moist crumbs. Avoid overbaking or the cake might dry out.
Can I add toppings or frost this cake?
Absolutely. A drizzle of nut butter, a spoonful of Greek yogurt, or even a swipe of cream cheese frosting works great. It also tastes amazing plain, straight from the pan.
How should I store leftovers?
Keep leftovers in an airtight container at room temperature for a day or two. For longer storage, pop it in the fridge. It’ll stay fresh for up to 5 days. You can also freeze individual slices and thaw them as needed.
Can I make this into muffins?
Yes. Just pour the batter into muffin tins and reduce the baking time. Start checking for doneness around the 20-minute mark.
