Step 1

Pre-heat the oven to 350F and line a 9×9″ baking pan with parchment paper.

Step 2

Add all of the crumble ingredients to a medium bowl. Use your hands to clump the ingredients together until a wet, sand-like texture forms. Set aside.

Step 3

In a large bowl, add all cake ingredients (except greek yogurt!) until very smooth. Then, fold in the greek yogurt to the batter.

Step 4

Pour half the batter into the prepared baking pan. Sprinkle on a layer of crumble. Layer in the remaining half of the batter, then finish the top with the remaining crumble mixture.

Step 5

Bake for 35-45 minutes, until a toothpick slid through the center comes out clean and it no longer jiggles.

Step 6

Let cool completely before slicing. Serve and enjoy!
