To Make Crust:

In a large mixing bowl, whisk together 1 1/4 cups tapioca flour, almond flour, coconut sugar, cinnamon and baking powder. 

Add in eggs and combine with a wooden spoon till mixture looks very crumbly. 

Next, add in milk and continue mixing with a wooden spoon till mixture forms into a ball and is very sticky.

Add in remaining 1/4 cup tapioca flour and knead dough with hands until dough is soft and easy to work with. 

Cover countertop with tapioca flour and roll dough out to a 10x10 inch pizza crust. Sprinkle tapioca flour on top of dough, fold dough in half and transfer to a parchment paper lined pizza sheet. Unfold pizza onto sheet. 

Bake crust at 375 degrees for 15 minutes. 

While crust is baking, prepare cinnamon streusel by melting butter in a small dish and combining coconut sugar and cinnamon in another dish. 

When crust is done, remove from oven and spread butter over crust then sprinkle cinnamon/sugar mixture evenly on top of butter. 

Put crust back in the oven and bake for 5 more minutes at 375 minutes. 

While crust is baking, prepare Cream Cheese Frosting by blending cream cheese, butter, vanilla extract, powdered sugar and milk in a medium mixing bowl. 

When crust is done, remove from oven and slice, using a pizza cutter, into 8 big slices or 16 smaller slices. 

Pour cream cheese frosting over streusel and serve warm.
