Cinnamon Flop Cake Recipe
For the cake
1 ½ cups granulated sugar
4 tablespoons salted softened butter
1 egg, lightly beaten
1 teaspoon vanilla extract
2 cups sifted all-purpose flour
2 teaspoons baking powder
1 cup milk
For the topping
1 cup brown sugar, packed
1 teaspoon cinnamon
2 tablespoons salted butter, melted
Preheat the oven to 375 F.
Lightly grease a 9x9-inch pan.
In a large bowl, cream together the granulated sugar with 4 tablespoons of butter until the mixture resembles snow.
Add the egg and the vanilla extract to the bowl, and mix until well combined.
In a small bowl, whisk together the flour with the baking powder. Alternate adding the flour mixture to the batter with the milk, mixing well after each addition.
In a separate medium-sized bowl, mix together the brown sugar and cinnamon. Melt the remaining 2 tablespoons of butter, then add it to the brown sugar mixture, and mix until well combined.
In the prepared pan, add the cake batter, then sprinkle the brown sugar mixture on top of the cake batter.
Bake in the preheated oven for 30 to 35 minutes, until a toothpick inserted in the center of the cake comes out with a few crumbs.
Let cool for about 15 minutes, then serve warm.
