Ingredients
Method
- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and grease a 9-inch springform pan or a square baking dish.
- In a small bowl, combine the brown sugar, half cup of flour, and cinnamon. Work the cold, cubed butter into the mixture until it looks like coarse crumbs.
- In a large mixing bowl, beat the softened butter and granulated sugar together until pale and fluffy. Add the egg and vanilla extract, and mix until fully combined.
- In a separate bowl, whisk together the two cups of flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with the sour cream, mixing until just combined.
- Spread the batter evenly into the prepared pan. Place the peach slices on top in a single layer and sprinkle the streusel mixture over the peaches.
- Bake for 40 to 50 minutes, checking for doneness with a toothpick.
- Let the cake cool in the pan for at least 15 minutes before serving.
Notes
Use room temperature eggs and sour cream for best results. If peaches are very juicy, toss them in a tablespoon of flour before adding to the batter.
