Recipe Instructions

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Butter a 9x12-inch baking dish generously.
Step 2
Mix dry ingredients: Whisk flour, baking powder, baking soda, and salt together in a bowl. Set aside.
Step 3
Make the crumble: Combine walnuts, brown sugar, white sugar, melted butter, cinnamon, and salt in a bowl. Mix until walnuts and sugar are thoroughly coated with butter.
Step 4
Add dry flour mixture to wet ingredients; whisk just until flour disappears. Do not overmix.
Step 5
Gather all ingredients.
Step 6
Mix the wet ingredients: Cream sugar and butter together in another bowl with a spatula until well blended.
Step 7
Add 1 egg and whisk until mixture is smooth, 2 to 3 minutes.
Step 8
Whisk in second egg until thoroughly incorporated. Add yogurt and vanilla; whisk together.
Step 9
Remove cores from apples. Cut across into 1/8- to 1/4-inch slices. Stack up a few slices, make a cut down the center, and dice across into cubes.
Step 10
Add to cake batter, folding in with a spatula until just combined.
Step 11
Spread 1/2 of the batter evenly into the bottom of the prepared baking dish. Scatter 1/2 of the crumble mixture evenly over the top.
Step 12
Top with the rest of the batter in dollops. Spread carefully to evenly distribute, trying not to disturb the crumbs.
Step 13
Top with the rest of the crumb mixture. Press crumbs into the batter very gently.
Step 14
Bake in the center of the preheated oven until a toothpick or bamboo skewer inserted into the center comes out clean, about 40 minutes.
Step 15
Let cool to room temperature, about 30 minutes, before slicing and serving.
