Instructions
Crumb Topping
- If possible, start the crumb topping at least 2 hours if not 12 hours before you plan to bake the crumb cake. This allows moisture to evaporate so the crumbs are less likely to sink to the bottom of the batter.
- Melt the butter and coconut oil together in a small pan or a microwave-safe bowl. In a medium bowl, whisk together the flour, muscovado brown sugar, salt, cardamom, ginger, and cloves. Pour in the melted butter and coconut oil, then gently toss everything together with a fork. It's not necessary for everything to completely incorporate yet - don't overwork the crumb. Add the coconut flakes and chopped nuts, then lightly toss everything together in with the fork or your fingers.
- Spread the topping out on a quarter sheet tray and let it dry.
Cake
- Preheat oven to 300 F. Line a 9-inch (23-cm) springform or round cake pan with parchment paper to cover the bottom and then lightly spray the sides and bottom with nonstick baking spray.
- In a medium bowl, whisk together the flour, baking soda, and salt.
- In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar together on medium speed until lightened in color and fluffy in texture, about 2-3 minutes.
- Beat in the eggs at medium speed, one at a time, letting the first incorporate fully before adding the second. Scrape down the sides of the bowl and beat for an additional 60 seconds. The mixture should be completely homogeneous.
- Add the sour cream and vanilla to the mixer bowl and beat on medium speed until just incorporated.
- Add the flour mixture in thirds to the creamed mixture, beating on low after each addition until just combined.
- Pour the batter into the prepared round cake pan and use an offset spatula to even the top of the batter. Break up the dried-out crumb topping and evenly scatter pieces across the cake batter, including along the edge.
- Bake the cake for 55 minutes, until golden brown on top and beginning to gently pull away from the sides. A toothpick inserted in the center should come out clean. Place the cake on a cooling rack to cool to room temperature, then serve.
