Step 1

Preheat the oven to 350°F

Step 2

In a mixer or food processor or bowl... combine the flour, baking powder, and sugar. Slowly add the butter 1 Tablespoon at a time. Pulse/mix/cut the butter into the dry ingredients. You want it to look like wet sand... and clump when you pinch it.

Step 3

Divide this streusel mixture into ⅔ and ⅓. Press the ⅔ into the bottom and approximately 1 to 1½ inches up the side of a springform pan. You don't want it TOO thick in the corners, so press it in. Thickness should be about ¼ - ⅓ inch across bottom and sides.

Step 4

Bake this for 15 minutes

Step 5

While the shell is baking, combine the Applesauce, Cornstarch, Vanilla Extract, and Cinnamon in a medium bowl. Make sure not to leave any lumps of cinnamon or cornstarch.

Step 6

Add the applesauce mixture to the pre-baked shell.

Step 7

Crumble the rest of the streusel mixture over the applesauce evenly. Use your fist to squeeze it so you get bigger bits as well as just crumbs.

Step 8

Bake 35 minutes.

Step 9

Remove from oven and let cool on a rack.
