Ingredients
Method
- Preheat oven to 325°F (163°C) and line a 9×9-inch baking pan with parchment paper.
- Melt the butter and allow it to cool for 5 minutes.
- Whisk together melted butter, brown sugar, eggs, buttermilk, and vanilla extract.
- In a separate bowl, combine flour, baking powder, baking soda, and salt.
- Fold the dry ingredients into the wet ingredients until just combined.
- Make the crumb topping by mixing flour, sugar, cinnamon, nutmeg, and cold butter until crumbly.
- Spread batter into the prepared pan and sprinkle the crumb topping evenly over the surface.
- Bake for 38–42 minutes or until a toothpick inserted in the center comes out clean.
- Cool in the pan for 20 minutes before slicing and serving.
Notes
For the best texture, avoid overmixing the batter and allow the cake to cool before slicing. Store covered at room temperature for up to 4 days or freeze for up to 2 months.
