Think of a chocolate cake that needs only four ingredients, no flour or refined sugar. With overripe bananas, Dutch‑process cocoa, eggs and maple syrup, you can whip up a fudgy, deep‑chocolate treat in about an hour.
For the batter you’ll need four large, overripe bananas (about 383 g), 54 g of Dutch‑process cocoa powder, two large eggs and three tablespoons of maple syrup. The bananas do most of the work, giving natural sweetness and that silky, velvety texture. Dutch‑process cocoa is richer and less bitter than its natural counterpart, so the flavor stays smooth. If you’re watching sugar, you can leave the maple syrup out entirely – the bananas will still keep things moist.
Line a six‑inch round springform pan with parchment paper on the bottom and a strip on the sides to keep the cake from sticking. Set your oven to 177 °C (350 °F). In a blender, combine the mashed bananas, cocoa, eggs and maple syrup. Blend on high until no banana lumps remain – the batter should look thin and glossy. This is the moment when you’ll see that unmistakable sheen that signals the cake is ready.
Pour the batter into the prepared pan, tap the pan gently to release any air pockets, then smooth the top with a spatula. Bake for 60 to 70 minutes; the cake will rise, develop a few cracks on top, and no longer look liquidy. A light toothpick test should come out clean, indicating doneness. Don’t rush – the cake needs that full, even bake to achieve the right fudgy crumb.
Let the cake cool in the pan for a few minutes, then slide it onto a wire rack to finish cooling. Once it’s completely set, place it uncovered in the fridge for at least a couple of hours – this chilling step firms the cake up and makes slicing a breeze. When you’re ready to serve, lift the sides with a spatula and cut with a sharp knife. The result is a moist interior, lightly sweet on the edges, and a chocolate‑banana flavor that feels indulgent but not overpowering.
If you’re craving a touch of extra decadence, whisk a small amount of coconut milk with dark chocolate chips until smooth and drizzle over the warm cake. Or simply enjoy it as is. Store leftovers in an airtight container in the fridge for up to a week, or freeze for longer storage – thaw at room temperature before serving.
Grab a blender, a springform pan, and your pantry staples, then give this 4‑ingredient banana chocolate cake a try. It’s a quick, low‑sugar dessert that feels like a treat, and you’ll have a new go‑to recipe that can be whipped up whenever the craving hits.
