This Plum Coffee Cake bakes up sweet and fragrant with jammy sliced plums nestled in a buttermilk almond cake. Brush the plums with melted butter and sprinkle with sugar before baking for a caramelized sugar top.

1. Preheat oven to 350 degrees F.   2. In a medium bowl, whisk together all-purpose flour, almond flour, baking powder, baking soda, and salt. Set aside.

Dry Ingredients

3. In a large bowl, beat butter and sugar together at high speed until light and fluffy, about 2 minutes. 4. Add eggs one at a time, beating on medium speed after each, until fully incorporated.  Add vanilla and almond extracts and beat briefly to combine.

Wet Ingredients

5. Add a third of the flour mixture and beat on low speed until combined, then add half the buttermilk and beat on low speed again. Repeat with remaining third of flour mixture, the rest of the buttermilk, and end with the last third of the flour mixture.

Combine

6. Spread the batter into a greased 9-inch springform pan.  Arrange sliced plums, skin up in whatever pattern you like, over top of the batter.  Feel free to really crowd them in there – the higher the plum-to-cake ratio, the better.

Assemble

7. Brush melted butter evenly over top of the plums and cake batter.  Sprinkle the remaining tablespoon of sugar evenly over top. Bake for 45-50 minutes, until risen, browned, and a tester inserted in the center of the cake comes out clean or with a few moist crumbs.

Bake!

8. Cool completely before serving at room temperature!
