Ingredients

For the Banana Chia Cake

• 1 ripe banana
• 1 large egg
• ¼ cup (60 ml) milk of choice
• 1 tablespoon maple syrup or honey
• ½ cup (45 g) rolled oats
• 1 tablespoon chia seeds
• ½ teaspoon baking powder
• ½ teaspoon vanilla extract
• A few fresh blueberries for topping

For the Blueberry Lava Center

• 1 teaspoon maple syrup

How to Make Banana Blueberry Chia Lava Cake

1. Make the Blueberry Lava

Add the blueberries and maple syrup to a small saucepan.

Cook over medium-low heat, gently crushing some of the berries as they soften. Stir in the chia seeds and continue cooking until the mixture becomes thick, glossy, and jammy.

Remove from the heat and set aside.

2. Prepare the Batter

Add the banana, egg, milk, maple syrup, rolled oats, chia seeds, baking powder, and vanilla to a blender.

Blend until the mixture is smooth and creamy.

The batter should be fairly thick with small chia seed specks throughout.

3. Assemble the Lava Cake

Lightly grease a ramekin.

Pour about ⅓ to ½ of the batter into the bottom.

Spoon 1–2 tablespoons of blueberry chia filling into the center, keeping it slightly away from the edges.

Pour the remaining batter over the blueberry filling until completely covered.

Top with a few fresh blueberries.

4. Bake

Bake at 350°F (175°C) for 12–15 minutes, or until the top looks fluffy and the edges are set.

The center should stay slightly soft so the blueberry filling remains gooey.

5. Let It Rest

Allow the cake to cool for about 1 minute before carefully turning it out onto a plate.

You can also enjoy it directly from the ramekin.

6. Cut and Enjoy

Slice straight through the center and watch the warm blueberry chia filling flow out.

Serve immediately while the cake is still warm and soft.

Tips for the Perfect Lava Center

Don’t overbake it. Overbaking can make the cake dry and cause the blueberry center to lose its gooey texture.

Use a very ripe banana. The riper the banana, the sweeter and more flavorful your cake will be.

Keep the filling in the center. Avoid spreading the blueberry mixture all the way to the edges so the batter can completely surround it.

Let the blueberry mixture thicken first. A thicker filling creates a richer, jammy lava center instead of disappearing into the batter.

Easy Variations

You can easily customize this recipe.

Try adding a pinch of cinnamon for extra warmth, swapping blueberries for raspberries or strawberries, using honey instead of maple syrup, or adding a few dark chocolate chips for an even more indulgent center.

For extra protein, serve the warm cake with Greek yogurt on the side.
