Ingredients & Tools

Core 4 ingredients

23 overripe bananas (the mushier, the better)
cup plain Greek yogurt (fullfat for extra moisture, lowfat if youre watching calories)
2 large eggs
teaspoon baking powder

Optional natural sweeteners & addins

If you like a touch more sweetness, drizzle a tablespoon of honey or maple syrup (just remember it adds a bit of sugar). A splash of vanilla extract, a pinch of cinnamon, or chopped walnuts can turn this basic cake into a flavor adventure.

Musthave kitchen tools

Mixing bowl (preferably stainless steel)
Handmixer or sturdy fork
Silicone loaf pan (95in works great)
Oven thermometer (helps keep the bake at the right temp)

StepbyStep Method

Prep phase (5min)

Start by mashing the bananas until there are no large chunks left think a smooth, bananabutter consistency. In a separate bowl, whisk the eggs until theyre lightly frothy, then fold in the yogurt. The mixture should look glossy and a little thick.

Visual cue checklist

Banana mash: no streaks, completely blended.
Yogurtegg blend: smooth, no lumps.

Mixing & folding (3min)

Combine the mashed bananas with the yogurtegg mixture, sprinkle the baking powder over the top, and fold gently. Overmixing can deflate the batter, resulting in a dense cake, so keep the motion light and airy.

Common mistake to avoid

If you stir vigorously, glutenlike structures (from the bananas starch) can form, making the crumb heavy. A gentle hand is the secret to that moist banana cake with yoghurt texture.

Baking (30min @350F / 175C)

Pour the batter into the greased loaf pan, smooth the top with a spatula, and pop it into the oven. Halfway through, rotate the pan to ensure even browning. Test for doneness by inserting a toothpick in the center it should come out with a few moist crumbs, not wet batter.

Oven tips

Use an oven thermometer to confirm the oven isnt running hot. A hotter oven can dry out the cake before the center sets.

Cooling & serving

Let the cake rest for 10minutes, then run a thin knife around the edges and gently lift it out of the pan. Slice warm with a light drizzle of honey or a dollop of extra yogurt, and enjoy!
