How to Make Walnut Banana Upside Down Cake
- Preheat oven to 325°F (160°C). Grease and flour a 9-inch diameter cake pan with 2-inch high sides.
- **Make the topping:** In a medium saucepan, combine 1/2 cup (100g) packed light brown sugar and 1/2 cup (113g) unsalted butter over low heat. Stir until butter melts and the mixture is smooth.
- Pour the melted butter-sugar mixture into the prepared cake pan. Spread evenly to coat the bottom.
- Drizzle 1/4 cup (60ml) maple syrup over the sugar mixture. Sprinkle 1/2 cup (60g) chopped walnuts evenly over the syrup.
- Arrange 2-3 ripe bananas, peeled and sliced lengthwise, in concentric circles on top of the walnuts, slightly overlapping.
- **Make the cake batter:** In a medium bowl, whisk together 1 1/2 cups (180g) all-purpose flour, 2 teaspoons baking powder, 1 teaspoon ground cinnamon, and 1/4 teaspoon salt.
- In a separate large bowl, cream together 1/2 cup (100g) unsalted butter and 1 cup (200g) granulated sugar until light and fluffy.
- Beat in 2 large eggs one at a time, then stir in 1 teaspoon vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with 1/2 cup (120ml) milk, beginning and ending with the dry ingredients. Mix until just combined.
- (Optional) Stir in 1 tablespoon of rum.
- Pour the batter evenly over the banana and walnut topping.
- Bake for 55-65 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cake cool in the pan for 10-15 minutes.
- Run a knife around the edges of the pan to loosen the cake.
- Place a serving plate upside down over the cake pan.
- Carefully invert the cake onto the plate.
- Let stand for a few minutes before serving warm. Top with whipped cream, if desired.
