For the streusel topping:
For the cake:
Preheat your oven to 350°F (175°C) and grease an 8-inch square baking dish.
In a small bowl, make the streusel topping by mixing flour, brown sugar, and cinnamon. Cut in the cold butter with a fork or pastry cutter until the mixture is crumbly. Set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon.
In a large bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add eggs one at a time, beating well after each addition. Mix in the vanilla extract.
Add the dry ingredients to the wet mixture in two additions, alternating with the sour cream. Mix until just combined.
Gently fold in the diced apples.
Pour the batter into the prepared baking dish and spread evenly. Sprinkle the streusel topping evenly over the batter.
Bake for 40 to 45 minutes or until a toothpick inserted into the center comes out clean.
Let cool before serving.
Use tart, firm apples like Granny Smith for best flavor and texture.
Always measure flour properly—spoon and level rather than scooping.
Don’t skip the sour cream; it’s essential for keeping the crumb moist.
Add chopped pecans or walnuts to the topping for extra texture.
To make it ahead, store unbaked batter and topping separately in the fridge overnight and bake fresh.
Pairs perfectly with black coffee or a lightly spiced chai latte.
