Step 1

In a medium bowl, add the cold cubed butter, flour, and confectioners sugar. Using your fingers, sift the flour mixtur over the butter and then start breaking down each cube into pea-sized pieces. When done, every ingredient should be well incorporated. (It is ok to have a few chunks.) Place in the refrigerator until ready to add the crumble.

Step 2

Preheat oven to 475°F.

Step 3

In a large bowl, add the self-rising flour and yogurt. Use a spoon to mix together as well as you can, then switch to your clean hands. Mix with hands until ingredients are coming together and then turn out onto a clean surface to knead for about 5 minutes. If the dough is too dry (crumbly), add a tablespoon of yogurt. If it is too wet, add a tablespoon of self-rising flour.

Step 4

Once the dough is kneaded and smooth, roll it out into a 10-12 inch circle. It should be about 1/4 inch thick.

Step 5

Place dough on a parchment-lined pizza stone or a parchment-lined baking sheet. Bake for 8-10 minutes, or until the edges just start to brown. Remove from oven. (It will bake again once toppings are added.)

Step 6

While the dough is baking for the first time, melt together butter, sugar, and cinnamon in microwave for about 30 seconds. Stir.

Step 7

In a separate bowl, mix confectioners' sugar and 1 tablespoon milk until smooth and creamy. If too thick, and in another tablespoon milk. Set aside.

Step 8

After the dough has been removed from the oven, brush the cinnamon butter over the dough in a thin layer, covering the entire surface.

Step 9

Sprinkle the cold crumble topping over the cinnamon butter, getting out to the edges.

Step 10

Place back into the oven for 6-8 minutes, or until the crumble no longer appears wet and is starting to turn golden brown.

Step 11

When done, remove from the oven and let sit for about 5-10 minutes.

Step 12

After it has cooled down a little bit, drizzle with all of the glaze. Serve immediately.
