Ingredients
- 1 and 1/2 cups gluten-free all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon ground cinnamon, optional
- Pinch of salt
- 1/2 cup unsalted butter, at room temperature
- 3/4 cup granulated sugar
- 2 eggs, room temperature
- 1 teaspoon vanilla extract
- 3/4 teaspoon almond extract
- 1/2 cup buttermilk
- 6 medium plums, sliced
- 1/2 cup chopped almonds
For the crumble:
- 1/3 cup gluten-free all-purpose flour
- 1/4 cup light brown sugar
- 2 tablespoons unsalted butter (28g), cold and diced
Instructions
- Preheat the oven to 350°F (180°C). Line an 8-inch square pan or a 9-inch round baking pan with parchment paper. Set aside.
- For the crumble: place the sugar, gluten-free all-purpose flour, and diced cold butter in a small bowl. Rub together with your fingertips until crumbs form. Place the crumbs on a plate and let them chill in the freezer.
- For the cake: whisk together gluten-free all-purpose flour, baking powder, baking soda, salt, and ground cinnamon in a medium bowl. Set aside.
- In a large bowl, beat the softened butter and sugar on high speed using a hand mixer or stand mixer fitted with a paddle attachment until pale and smooth. Add the eggs, vanilla extract, almond extract, and buttercream and beat on medium speed until integrated. The mixture is curdled. Add the dry ingredients and keep beating on low speed until combined. Don’t overmix, just until combined.
- Pour the mixture into the prepared pan and smooth it out with a spatula.
- Top the cake with the sliced plums and sprinkle with the streusel and chopped almonds.
- Bake for 40 minutes or until a toothpick inserted in the center comes out clean. Keep in mind that all ovens are different.
- Let cool and lift the parchment paper.
