Why You’ll Love This Easy Paleo Banana Coffee Cake

This cake brings together everything you love about banana bread and coffee cake in one pan.
First, it’s naturally sweetened primarily with ripe bananas, which give it deep flavor and natural moisture. The coconut crumble adds a slightly crisp, cinnamon-kissed topping that contrasts beautifully with the soft crumb.
It’s also:
- Grain-free and gluten-free
- Paleo-friendly
- Made with simple pantry ingredients
- Perfect for meal prep
- Easy enough for beginner bakers
The texture is tender and slightly dense (as coconut flour bakes tend to be), but incredibly moist and flavorful. The hint of cinnamon and optional coffee granules gives it that classic coffee cake vibe without overpowering the banana flavor.
Ingredients for Easy Paleo Banana Coffee Cake with Coconut Crumble
For the Banana Cake Batter
- 3 ripe bananas, mashed
- 3 large eggs
- 1/3 cup coconut sugar
- 1/4 cup tapioca flour
- 1/2 cup coconut flour
- 1 teaspoon cinnamon
- 1/2 teaspoon baking powder
- 1/4 teaspoon sea salt
- 1 teaspoon vanilla extract
- 1 teaspoon instant coffee granules (optional)
For the Coconut Crumble Topping
- 1/2 cup chopped walnuts
- 2 tablespoons coconut sugar
- 1/2 teaspoon cinnamon
- 2 tablespoons melted coconut oil
Ingredient Notes
Bananas: Use very ripe bananas with brown spots. The riper they are, the sweeter and more flavorful your cake will be.
Coconut Flour: This flour absorbs a lot of liquid, so do not substitute it 1:1 with almond flour. If substituting, the recipe will need structural adjustments.
Tapioca Flour: Adds lightness and balance to the density of coconut flour. Arrowroot starch can work as a substitute.
Coconut Sugar: You may reduce it slightly if your bananas are very sweet. For a refined-sugar-free option, maple syrup can replace it, though you may need to slightly reduce other liquid ingredients.
Instant Coffee Granules: These enhance the “coffee cake” flavor but don’t make the cake taste like coffee. Omit if desired.
Walnuts: Pecans or chopped almonds work beautifully as alternatives.
Step-by-Step Instructions
Step 1 – Prepare the Pan and Oven
Preheat your oven to 350°F (175°C). Line an 8×8 or 9×9-inch baking pan with parchment paper, leaving overhang on the sides for easy removal.
Step 2 – Make the Coconut Crumble
In a small bowl, combine chopped walnuts, coconut sugar, cinnamon, and melted coconut oil. Stir until the mixture resembles a crumbly topping. Set aside.
Step 3 – Mix the Wet Ingredients
In a large mixing bowl, mash the ripe bananas until smooth. Add the eggs and vanilla extract, and whisk until fully combined and slightly frothy.
Step 4 – Combine the Dry Ingredients
In a separate bowl, stir together coconut flour, tapioca flour, coconut sugar, cinnamon, baking powder, sea salt, and instant coffee granules (if using).
Step 5 – Create the Batter
Slowly add the dry mixture into the wet mixture. Stir thoroughly until no lumps remain. The batter will thicken as the coconut flour absorbs moisture.
Let the batter rest for 2–3 minutes to fully hydrate.
Step 6 – Layer and Assemble
Spread half of the batter evenly into the prepared pan. Sprinkle half of the coconut crumble over the batter.
Add the remaining batter and gently smooth the top. Finish with the rest of the crumble topping.
Step 7 – Bake
Bake for 28–35 minutes, or until the center is set and a toothpick inserted comes out clean.
Turn off the oven and allow the cake to sit inside for an additional 5 minutes to prevent sudden deflation.
Step 8 – Cool and Slice
Remove from oven and let cool completely in the pan before lifting out using the parchment paper. Slice into squares and serve.
Pro Tips for Success
- Use ultra-ripe bananas for maximum sweetness and moisture.
- Measure coconut flour carefully — too much will dry out the cake.
- Let the batter rest briefly before baking to allow full hydration.
- Do not overbake — coconut flour cakes dry quickly if left too long.
- Cool completely before slicing to prevent crumbling.
Flavor Variations
- Chocolate Chip Banana Coffee Cake – Add 1/3 cup dairy-free chocolate chips to the batter.
- Blueberry Banana Crumble Cake – Fold in 1/2 cup fresh blueberries.
- Pecan Streusel Version – Swap walnuts for pecans for a deeper, buttery flavor.
- Cinnamon Swirl Upgrade – Add a ribbon of cinnamon-coconut sugar in the middle layer.
- Almond Crunch Twist – Sprinkle sliced almonds on top before baking.
Serving Suggestions

This cake is incredibly versatile.
Serve it warm with:
- A cup of hot coffee or tea
- A dollop of coconut yogurt
- A drizzle of almond butter
- Fresh berries on the side
It also makes a wonderful brunch centerpiece or afternoon snack. Because it’s naturally sweetened and grain-free, it works well as a breakfast option that won’t feel overly heavy.

FAQ About Easy Paleo Banana Coffee Cake with Coconut Crumble
Can I make this nut-free?
Yes. Simply omit the walnuts and replace them with unsweetened shredded coconut or pumpkin seeds for crunch. The texture will still be delightful, and the flavor will remain warm and cinnamon-forward.
Can I substitute almond flour for coconut flour?
Not directly. Coconut flour absorbs significantly more moisture than almond flour. If you wish to use almond flour, the entire liquid and egg ratio would need adjusting, so it’s best to follow a tested almond flour recipe instead.
Does it taste like coffee?
No. The optional instant coffee granules simply enhance the depth of flavor and make it more “coffee cake-like.” You can skip them if you prefer a pure banana-cinnamon flavor.
Is this recipe truly paleo?
Yes, when made with coconut sugar and without dairy, this recipe fits within standard paleo guidelines. Always double-check ingredient labels to ensure compliance with your dietary needs.
Why is my cake dense?
Coconut flour naturally creates a slightly denser texture than wheat flour. Make sure you measured accurately and did not overbake, as excess baking time can also create dryness.
