Method
Preparation
- Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan or line it with parchment paper for easy removal.
- In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, cinnamon, and salt until well combined.
- In another bowl, cream the softened butter with the brown sugar until light and fluffy using an electric mixer on medium speed for about 2-3 minutes.
- Add the eggs, sour cream, and vanilla extract to the butter mixture. Mix until everything is smooth and fully incorporated.
- Gradually add the dry ingredients into the wet mixture, stirring gently with a wooden spoon or spatula until just combined. Avoid overmixing.
Crumb Topping
- In a separate bowl, mix equal parts of flour, granulated sugar, and brown sugar along with the cinnamon and softened butter using your fingers until you form pea-sized crumbles.
Baking
- Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle the crumb mixture generously over the top.
- Place the cake in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cake to cool in the pan for about 10 minutes before slicing and serving.
Notes
Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, freeze individual slices for up to 3 months. Reheat in the microwave for 20-30 seconds or in a preheated oven at 350°F for 10 minutes.
