Instructions
For the Topping + Filling
Topping: In a medium bowl, combine the flour, sugars, and cinnamon. Pour in the melted butter and mix until no dry bits remain. Set aside to cool.Filling: Combine the brown sugar and cinnamon in a small bowl. Set aside.
For the Cake
Grease or butter a 9 by 13-inch baking pan. Preheat oven to 350 degrees.In a large bowl, beat together the oil, sugar, eggs, discard, sour cream, and vanilla until well combined. Add the flour, baking powder, baking soda, and salt and beat on medium speed for 1-2 minutes, until very smooth.Transfer half the batter to the prepared baking pan and spread into an even layer with a spatula. This will be a very thin layer - it will puff up as it bakes! Sprinkle the filling over top to cover, then add the remaining batter, spreading into an even layer over the filling. Top with the crumble topping. Bake for 45-50 minutes, until a toothpick inserted into the middle of the cake comes out clean or with a few moist crumbs. Cool for 5-10 minutes before cutting.Leftovers can be covered and stored at room temperature for up to 3 days.
Notes
The discard - For most discard recipes, you can use discard in any form, but here, you really want it to be on the older side so it's quite liquid. The batter should be pourable.If you're using a glass baking dish, it will likely need to bake for longer. Be sure to do the poke test to check that it's baked through!
