Ingredients for banana cake recipe grams

Precision measurements transform humble bananas into a foolproof, velvety cake every time.

The bananas are the heart of this recipe—choose ones with black speckles but no mold. Trader Joe's often has perfect overripe bananas for this purpose. For the flour, King Arthur or Gold Medal brands yield the best texture. The butter must be room temperature—press a finger into it; if it leaves a slight indent, it's ready. Baking powder and soda should be fresh—if they're over six months old, test them with vinegar to ensure they still bubble. Walnuts and chocolate chips are optional but add delightful texture contrasts; toast the nuts in a dry pan for 3-4 minutes to enhance their flavor.

No ripe bananas? Unripe bananas baked at 200°F (95°C) for 20 minutes work in a pinch, though texture will differ slightly. Substitute brown sugar with maple syrup at equal weight, but reduce other liquids by 15g to maintain moisture balance. For a dairy-free version, replace butter with coconut oil (120g) and milk with almond milk (120ml). If you lack vanilla extract, 1 tsp vanilla sugar or the seeds from 1 vanilla bean suffice. For a gluten-free adaptation, use a 1:1 gluten-free flour blend (200g) and add 1 tbsp xanthan gum to improve structure.

Store baked cake in an airtight container at room temperature for up to 3 days or in the fridge for 5 days to preserve moisture. For longer storage, freeze slices wrapped in plastic for up to 3 months. To reheat, warm in the oven at 160°C (325°F) for 5-10 minutes to restore softness. This cake's precise measurements ensure consistent results—no guesswork, just reliable baking every time.

Step-by-step instructions for banana cake in grams

Precision meets simplicity—this method delivers moist, tender layers with perfect texture every time.

Mash the 300 g ripe bananas thoroughly in a large mixing bowl until completely smooth—no lumps should remain. I press them through a fine-mesh sieve for extra-smooth batter, which prevents dense pockets in the cake. The bananas should be ripe enough to mash easily with just a fork, but without any brown spots or overly mushy texture.

In a separate bowl, whisk together the 150 g granulated sugar and 100 g brown sugar until fully combined. This prevents sugar streaks in the final batter. Add the 120 g unsalted butter (already room temperature) and cream with an electric mixer on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this aeration creates the cake's signature tender crumb.

Add the mashed bananas to the sugar-butter mixture and mix on low speed for 1 minute until fully incorporated. The batter will look thick and slightly curdled, but that's normal. In a separate small bowl, whisk together the 2 whole large eggs, 5 ml vanilla extract, 120 ml milk, 2 g salt, 5 g baking powder, and 2 g baking soda. This pre-mix prevents overmixing when combined with the wet ingredients.

Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined—no more than 30 seconds. Overmixing develops gluten in the flour, resulting in a tough cake. The batter should be thick but pourable, with a few small flour streaks still visible. This ensures maximum moisture retention during baking.

Gently fold in the 80 g walnut halves and 80 g dark chocolate chips using a silicone spatula. I like to toast the walnuts first for enhanced flavor, but raw walnuts work too. Pour the batter into two 20 cm round cake pans lined with parchment paper, filling each ¾ full. Tap the pans firmly on the counter to remove any air bubbles—this prevents dome-shaped cakes.

Preheat your oven to 175°C (convection) and place the pans on the middle rack. The lower temperature ensures even baking without a dark crust. Bake for 35-40 minutes until a toothpick inserted into the center comes out clean. The edges should be golden brown, but the tops may still look slightly soft—this is normal for banana cakes.

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. I find this gradual cooling prevents cracking as the cakes shrink. Once fully cooled, level the tops with a serrated knife if needed—this ensures even layers for frosting or filling.

For the classic presentation, place one cake layer on a plate and spread a thin layer of buttercream frosting (made with the remaining 30 g butter and 50 g powdered sugar if desired). Add the second layer and repeat. The cake should have a moist, fudgy texture with subtle walnut and chocolate flecks throughout. Store in an airtight container for up to 3 days or freeze for longer storage.

Wine and beer pairings for this dish

Sweet White Wine

For this moist banana cake, I always reach for a dry Riesling from Germany or Austria—its crisp acidity and subtle honeyed notes complement the banana's natural sweetness without overpowering it. A Pinot Grigio from Italy also works beautifully, especially if you've added chocolate chips. Serve chilled to enhance the wine's brightness against the cake's richness. 🍷

Fruity Red Options

If you prefer red wine, a light-bodied Beaujolais or Pinot Noir from Oregon pairs wonderfully. These wines have enough fruitiness to match the banana's sweetness while their acidity cuts through the cake's density. Avoid heavy Cabernets—they'll clash with the delicate banana flavor. Let the wine breathe for 10 minutes before serving to open up its aromas.

Creamy Beer Pairings

A Belgian-style witbier with its citrusy coriander notes creates an unexpected but delightful contrast to the banana cake. For a more traditional pairing, try a light American lager like Miller Lite—its clean, crisp profile balances the cake's sweetness. For a richer option, a honey ale enhances the banana's natural sweetness beautifully. 🍺

Coffee or Tea?

If you're not a wine or beer drinker, consider pairing this cake with a strong espresso or chai latte. The bitterness of coffee enhances the cake's caramelized banana notes, while the spices in chai complement the warm flavors. For a non-caffeinated option, a vanilla chai tea made with 2 bags steeped in 240 ml hot milk creates a perfect harmony with the cake's vanilla extract.

Seasonal Adaptations

In summer, I love pairing this cake with a sparkling rosé—its bubbles cleanse the palate between bites. For fall, a dry sparkling wine like Prosecco adds festive elegance. In winter, a mulled wine with cinnamon and orange peel enhances the cake's warm spices. The key is matching the wine's or drink's acidity and sweetness to the cake's natural flavors.
