Lori Sandler shares her recipe for delicious egg-, nut-, and dairy-free blueberry cake.
Preheat oven to 350 degrees. Spray a 9-by-9-inch or 12-by 18-inch baking pan with nonstick cooking spray; set aside.
In a medium bowl, whisk together cake flour, baking powder, and salt; set aside. In a small bowl, whisk together egg replacer and seltzer until dissolved and frothy; set aside.
Cream margarine in the bowl of an electric mixer fitted with paddle attachment. Add 1 cup sugar and continue mixing until creamed together, scraping down sides of bowl as necessary. Add egg replacer mixture and vanilla; beat until well combined, scraping down sides of bowl as necessary. Slowly add flour mixture in three additions, alternating with soy milk and beginning and ending with flour mixture, beating well after each addition. Continue beating until batter is smooth and stiff. Gently fold blueberries into batter.
Pour batter into prepared pan, spreading evenly. In a small bowl, mix together remaining 1/4 cup sugar and cinnamon; generously sprinkle over cake. Transfer cake to oven and bake until a cake tester inserted into the center comes out clean, about 45 minutes, rotating pan halfway through baking. Cake can be served warm straight from the pan.
