This is the best vegan coffee cake ever starting with a soft cake, a cinnamon-infused filling and a buttery crumbly topping to finish it off. It may be the best way to start out the day!
Preheat oven to 350°F/175°C. Spray a 9x9 pan with vegetable spray.
For the Crumble Topping/Filling:
In a bowl, combine the brown sugar, cinnamon, cocoa powder, flour, and softened vegan butter. Mix until crumbly. This mixture will serve as both the crumble topping and filling.
For the Coffee Cake:
Combine the milk and vinegar to make buttermilk. Set aside.
In a large mixing bowl use an electric mixer to cream together the vegan butter and sugar. You can use a spoon but stir vigorously until light and fluffy. Beat in the buttermilk, ground flax meal, cornstarch, and vegan yogurt.
In a medium-size bowl, combine the flour, baking powder, and salt. Stir to combine.
Add the flour mixture to the milk mixture. Stir until just combined.
Coffee Cake Assembly:
Pour half of the coffee cake batter into the prepared baking dish.
Sprinkle a generous layer of the crumble topping/filling mixture over the batter.
Pour the remaining coffee cake batter over the crumble mixture.
Sprinkle the rest of the crumble topping/filling mixture evenly over the top of the cake batter and gently press it down.
Bake for 50 to 55 minutes, until a toothpick inserted in the middle of the cake, comes out clean. The crumble topping should be golden brown.
When done, remove from the oven and allow to cool slightly before serving.
Notes
Icing
Make it dramatic by adding a drizzle of icing on top. Combine 1/2 cup powdered sugar with 1 tablespoon of vanilla-flavored plant-based milk. Stir to combine and drizzle over the top.
Cocoa Powder
We'll add cocoa powder to the filling to give it a dramatic contrast between the filling and the cake. You can leave it out or substitute a tablespoon of molasses.
Make-Ahead
You can make the batter the night before and assemble the cake in the pan, then cover and bake it in the morning. You'll need to add about 5 minutes of bake time to make up for the chilliness of the dough.
Vegan Yogurt
You can substitute vegan sour cream or whipped silken tofu.
