Buckwheat Ginger Banana Cake with Chocolate

PIn it

Introduction

This buckwheat ginger banana cake uses dark chocolate as a textural contrast to the soft, spiced crumb—a pairing that works because the chocolate stays distinct rather than melting through. The recipe comes together in one bowl and bakes in 45 minutes, making it a practical weeknight dessert or coffee-break cake that doesn’t require a mixer.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 45 minutes
• Total Time: 60 minutes
• Servings: 8

Ingredients

• 1 cup (135 g) buckwheat flour
• 1 tsp baking powder
• 1 tsp baking soda
• ¼ cup (60 ml/70 g) maple syrup
• ¼ cup (60 ml/65 g) unsweetened applesauce
• Juice of ½ lemon
• 1 tbsp (8 g) grated fresh ginger
• 3 very ripe bananas (should have dark spots on the peel)
• ¼ cup (30 g) roughly-chopped dark chocolate or chocolate chips

Instructions

1. Preheat oven to 170°C (338°F).
2. Mix the buckwheat flour, baking powder and baking soda in a bowl, and set aside.
3. Mix the maple syrup with the applesauce, the lemon juice, and the grated ginger. Mash the bananas using the back of a fork before mixing them with the other wet ingredients.
4. Combine the dry ingredients with the banana mixture. Be careful not to overmix-you don’t want to beat out all of the air.
5. Once everything is well-mixed, add the dark chocolate and gently mix again.
6. Line a cake pan (20 x 20 cm/ 8 x 8 inch) with parchment paper and pour the batter into it.
7. Place in the oven and bake for about 45 minutes or until a toothpick inserted in the center comes out clean.

Variations

Spiced variation: Add ½ tsp ground cinnamon and a pinch of ground cloves to the dry ingredients. This deepens the ginger’s warmth without overpowering the banana.

Nuts instead of chocolate: Swap the dark chocolate for ¼ cup roughly-chopped walnuts or hazelnuts. The crunch provides a different textural anchor and adds a slight earthiness that complements buckwheat well.

Extra ginger kick: Increase the fresh ginger to 1½ tbsp or add ¼ tsp ground ginger to the dry mix. This makes the cake spicier and cuts through the sweetness of the maple syrup.

Applesauce reduction: If you prefer a denser, less moist cake, reduce the applesauce to 3 tbsp and add 1 tbsp of neutral oil. This shifts the moisture balance and creates a tighter crumb.

Tips for Success

Use bananas with dark spots on the peel—they’re sweeter and softer, which means they mash more easily and contribute more natural sugar, reducing the need for additional sweetening.

Don’t overmix once you combine the wet and dry ingredients. Stir just until you don’t see dry flour streaks. Overmixing toughens the crumb by developing gluten in the buckwheat.

Check the cake at 40 minutes by inserting a toothpick in the center. Buckwheat cakes can brown quickly; if the top is dark but the toothpick still has wet batter clinging to it, tent the pan loosely with foil for the final 5 minutes.

Measure your maple syrup by weight (70 g) if you have a scale, since it’s thick and can compress differently depending on how you scoop it. Consistent measurement ensures even rise and texture.

Storage and Reheating

Store the cooled cake in an airtight container at room temperature for up to 2 days, or in the fridge for up to 4 days. It will firm up slightly when cold but remains moist.

This cake does not freeze well; the texture becomes dense and the moisture distribution breaks down after thawing.

To reheat, wrap a slice loosely in a damp paper towel and microwave for 15–20 seconds, or warm it in a 160°C oven for about 8 minutes covered with foil.

FAQ

Why did my cake sink in the middle?

Underbaking is the most common cause. The center should feel just set to the touch when you remove it, and a toothpick should come out with only a few moist crumbs, not wet batter. If the edges are done but the middle isn’t, tent the top with foil and bake another 5 minutes.

Can I use regular wheat flour instead of buckwheat?

Yes, use the same weight (135 g) of all-purpose flour. The flavor will shift—you’ll lose the nutty, slightly earthy tone of buckwheat—but the structure will be similar. The bake time should remain about 45 minutes.

The chocolate pieces seem to sink to the bottom. Is that normal?

What if I don’t have fresh ginger?

Use ¾ tsp ground ginger as a direct substitution. Ground ginger is more concentrated, so use slightly less than you would fresh. Add it to the dry ingredients rather than the wet mix.
