Directions

• Prepare the “White” Sugar Cookie Streusel: In a large bowl, whisk together the flour and sugar. Using a pastry blender, cut in the butter until mixture resembles a coarse meal. Set aside.
• Arrange oven rack in lower third of oven and preheat oven to 350º F. Grease 9-inch round nonstick springform pan with shortening and dust with flour, tapping out the excess. Set aside.
• Prepare the “Red & Blue” Berry Cake: In a medium bowl, whisk together flour, baking powder and salt until well combined. Using an electric stand mixer fitted with paddle attachment, or handheld mixer and large bowl, cream together butter and sugar until light and fluffy, about 3 minutes. Add lemon zest and vanilla; beat until combined.
• Add the eggs, one at a time, blending well after each addition on medium speed and scraping sides and bottom of bowl as necessary. (Mixture may look slightly separated. Don’t worry. It will pull together with the addition of flour.) Add flour gradually while mixing at low speed until mixture is just blended. Do not overmix. (Batter will be thick and very heavy.) Using rubber spatula, carefully fold in berries until distributed evenly.
• Using rubber spatula, scrape batter into prepared pan. With spatula, spread batter evenly to pan edges and smooth the top. Use hand to clump portions of streusel by squeezing and use fingers to sprinkle small clumps of streusel evenly over top of batter. Repeat process with remaining streusel.
• Bake in preheated oven until toothpick inserted into center comes out clean, about 55 to 60 minutes. Remove cake from oven and place on wire cooling rack. Immediately, sprinkle sugar over the top of cake and run thin metal icing spatula around edge of pan to loosen cake from sides of pan. This will prevent the berries from sticking to the sides of pan and will make removing easier. Cool for 15 minutes.
• Unmold cake by removing sides of pan. Cool until just warm or to room temperature, about 1 hour. Slice into wedges and serve.
