For the Cake
- Vegetable oil, cooking spray
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 6 ounces (about 1 1/2 cups) raspberries
- 2/3 cup blackberry jam
- 3/4 cup (1 1/2 sticks) unsalted butter, softened
- 1 1/4 cups granulated sugar
- 1 1/4 teaspoons finely grated lemon zest
- 3 large eggs
- 2 teaspoons pure vanilla extract
- 1 1/4 cups sour cream
For the Topping
- 1 cup all-purpose flour
- 2/3 cup packed light-brown sugar
- 1/4 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 3/4 cup sliced almonds, toasted
- 1/2 cup (1 stick) unsalted butter, softened
- 1/4 teaspoon pure almond extract
Preheat oven to 350 degrees. Make the topping: Whisk flour, brown sugar, cinnamon, salt, and almonds in a medium bowl. Using your fingers, work in butter until mixture forms coarse crumbs ranging in size from small peas to marbles. Sprinkle with almond extract; toss to combine.
Make the cake: Use cooking spray to coat a 10-inch tube pan with a removable bottom. Place pan on a baking sheet. Sift together flour, baking powder, baking soda, and salt into a medium bowl. Fold raspberries into jam in a small bowl.
Put butter, sugar, and zest into the bowl of an electric mixer fitted with the paddle attachment. Mix on medium-high speed until pale and fluffy, 3 to 4 minutes. Reduce speed to medium. Add eggs, 1 at a time, beating well after each addition and scraping down sides of bowl as needed. Mix in vanilla. Reduce speed to low. Mix in half the reserved flour mixture, followed by the sour cream. Add remaining flour mixture; beat until just combined.
Spoon half the batter into prepared pan. Mound berry mixture in a ring in center of batter. Top with remaining batter. Using a small offset spatula, smooth top. Sprinkle with the topping.
Bake until golden brown and a toothpick inserted into center comes out clean, 65 to 70 minutes. Let cool slightly on a wire rack, 10 to 15 minutes. Run a knife around edges of pan to loosen. Pull up on tube to lift cake from pan. Let cool on rack 15 minutes. Invert cake onto a baking sheet, removing tube portion, then reinvert onto rack to cool completely.
