Preparation Steps:
- Start by preheating your oven to 350°F (175°C). Grease your 9x13 inch baking pan generously with butter.
- In a medium bowl, whisk together the 2 cups of all-purpose flour, baking soda, baking powder, and salt. Set this mixture aside.
- In a large mixing bowl, cream together the 10 tablespoons of unsalted butter and 1 cup of granulated sugar until light and fluffy.
- Beat in the 3 large eggs one at a time, then mix in the 1 teaspoon of vanilla extract until well combined.
- Add the 1 cup of sour cream to the butter mixture, mixing until smooth.
- Gradually add the dry ingredient mixture to the wet mixture, stirring gently until just combined.
- In a separate bowl, combine the 3 cups of all-purpose flour, 1 cup of packed light brown sugar, 1 tablespoon of ground cinnamon, and 1 teaspoon of coarse salt. Add the 1 cup of room temperature unsalted butter and mix until crumbly.
- Pour the cake batter into the prepared baking pan, smoothing the top, and sprinkle the crumb topping over the batter.
- Bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted comes out clean.
- Let the cake cool in the pan for about 15 minutes, then transfer to a cooling rack to cool completely before serving.
Notes
- Ensure accurate flour measurement to prevent a dry cake.
- Don’t open the oven door too early to avoid a sunken center.
- Grease the pan thoroughly or use parchment paper for easy removal.
