Ingredients
- cooking spray
- 1 1⁄3 cups all purpose flour
- 1 packed cup light or dark brown sugar
- 2 teaspoons ground cinnamon
- 1/2 teaspoon freshly grated nutmeg
- 1/4 teaspoon fine sea salt
- 1/2 cup unsalted butter , at room temperature
Steps
- Preheat the oven to 350 degrees F (180 degrees C) with an oven rack set in the center of the oven. Grease a 9-inch square pan with nonstick spray, and line the pan with parchment paper, allowing at least 2 inch of excess on each side (these will act as handles to make for an easier removal later).
- Gather all ingredients.
- To make the crumble topping: Stir flour, brown sugar, cinnamon, nutmeg, and salt together in a bowl until combined. Add butter and use your hands or a pastry cutter to mix until butter is fully incorporated, and mixture forms moistened clumps. It should no longer appear powdery. Set aside.
- To make the coffee cake: Beat butter, sugar, and brown sugar in the bowl of an electric mixer fitted with the paddle attachment on medium speed until light and fluffy, 3 to 4 minutes.
- Add eggs, 1 at a time, mixing well on medium speed to incorporate and scraping the bowl well after each addition.
- Whisk flour, cinnamon, nutmeg, baking powder, baking soda, and salt together in a bowl to combine. Add about half of the mixture to the mixer and mix on low speed to combine, then scrape the bowl well.
- With the mixer running on low speed, add buttermilk in a slow, steady stream and mix until incorporated. Add remaining half of the dry ingredients and mix to combine.
- Pour half of the batter into the prepared cake pan, and spread into an even layer. Sprinkle about half of the crumble mixture over the batter in an even layer.
- Pour remaining batter on top, and spread into an even layer. Top batter with remaining crumble, scattering it fairly evenly across the surface.
- Transfer cake to the preheated oven and bake until a tester inserted into the center comes out clean or with a few moist crumbs, 35 to 40 minutes.
- Cool the cake completely in the pan, then use the excess parchment paper to gently unmold the cake and transfer to a cutting board. Slice the cake into 9 pieces, then peel it away from the parchment paper to serve.
