A great baking project for an afternoon at home.
1½ cups diced rhubarb
1 apple, cored and thinly sliced
1¼ cups sugar
8 tablespoons (1 stick) unsalted butter
1 teaspoon vanilla extract
1⅔ cups all-purpose flour
2 teaspoons baking powder
⅓ cup sliced almonds
Pinch of salt
1. Preheat the oven to 400°. Grease a 9-inch round pan.
2. Beat 1¼ cups sugar and the butter together using an electric mixer until well blended, light, and fluffy. Add eggs, one at a time, followed by vanilla extract, mixing well after each addition.
3. Turn mixer to low speed and slowly add in flour, baking powder, and a pinch of salt, mixing just until combined. Fold in rhubarb. Pour batter into the prepared baking pan. Smooth the top and place apple slices in a circular pattern on the batter. Sprinkle the almonds and a little additional sugar on top.
4. Bake in the preheated oven until a toothpick inserted into the center comes out clean, 35 to 45 minutes. Let cool, and serve warm or cold.
