How to Make Berry Crumb Cake Recipe: Prep: Preheat oven to 350˚F. Line the bottom of a springform pan with a ring of parchment paper. Grease sides lightly with butter.
In a large mixing bowl using an electric hand mixer (or stand mixer), beat together eggs and sugar on high speed 5 minutes until thick. Stir in 1/4 cup olive oil.
In a separate small bowl, whisk together flour and baking powder. Add 1/2 flour mixture to the batter, mixing on low speed just until incorporated. Stir in 1 Tbsp lemon zest and 1 tsp vanilla. With the mixer on low speed, add 1/3 cup club soda, mixing until incorporated.
Add remaining 1/2 of flour mixture, transfer to prepared pan and even out the top with a spatula. Place berries somewhat evenly over the top. How to Make Crumb Topping & Assembly:
In a medium bowl, combine the crumble topping ingredients. Rub the butter and flour together with your finger tips to create crumbs. Bake 45-50 min. until golden brown on top and a toothpick inserted in the center comes out clean. Ours was perfect at 48 min and be sure not to over-bake or the cake will turn out dry.
