Banana Cake
- 2 large eggs
- 2–3 ripe bananas, mashed (approx 250–300 g)
- 1/3 cup (80 ml) Greek yogurt
- 1 1/2 tsp (7.5 ml) vanilla extract
- 2 1/4 cups (270 g) all-purpose flour
- 1/4 cup (50 g) granulated white sugar
- 2 tsp (4 g) cinnamon
- 1 1/2 tsp (7.5 g) baking powder
- 1/4 tsp (1 g) baking soda
- 1/4 tsp (1.5 g) salt
Cinnamon Swirl
- 1/4 cup (50 g) granulated white sugar
- 2 tsp (4 g) cinnamon
Crumble Topping
- 1/4 cup (50 g) granulated white sugar
- 1/2 cup (60 g) all-purpose flour
- 1 1/2 tsp (3 g) cinnamon
- 1/4 cup (56 g) unsalted butter, cold and cubed
Instructions
- Preheat oven to 350°F (175°C). Grease and line an 8×8 inch baking pan with parchment paper.
- In a large bowl, whisk together the eggs, mashed bananas, Greek yogurt, and vanilla extract until well combined.
- In a separate bowl, combine the flour, sugar, cinnamon, baking powder, baking soda, and salt.
- Fold the dry ingredients into the wet mixture until just combined. Do not overmix.
- In a small bowl, combine the sugar and cinnamon for the cinnamon swirl.
- In another bowl, mix together the flour, sugar, and cinnamon for the crumble topping. Add the cold butter and knead with your fingers until coarse crumbs form, about the size of peas.
- Pour half of the cake batter into the prepared pan. Evenly sprinkle the cinnamon swirl mixture over the batter.
- Carefully spoon the remaining cake batter over the cinnamon swirl. (Tip: Dollop spoonfuls around the edges first, then fill in the middle to make spreading easier.)
- Evenly sprinkle the crumble topping over the top layer of batter.
- Bake for 25 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cake cool in the pan for at least 10 minutes before transferring it to a wire rack to cool completely.
Notes
- The riper your bananas, the better! We’re talking brown spots, almost black. This ensures maximum sweetness and that lovely banana flavor shines through.
- Spreading the second layer of batter over the cinnamon swirl can be a bit tricky. Try dolloping spoonfuls around the edges first, then fill in the middle. An offset spatula helps a ton here!
- Resist the urge to overmix your batter! Just fold until the dry ingredients are just combined. This keeps your cake tender and moist, not tough.
