Step 1

Preheat oven to 350°.

Step 2

Cream the butter and sugar together for 3 minutes.

Step 3

Scrape sides of bowl and add egg white and vanilla. Combine thoroughly.

Step 4

Mix in flour and baking powder until completely combined. The texture should be similar to playdoh. If it is too wet, at a little more flour. If it is too dry, at a little water. 1 1/2 cups is always about perfect for me.

Step 5

Roll the dough out until you have a 1/4 inch thick circle.

Step 6

Use a 4 inch circle cookie cutter and cut out the dough. Line each Silicone Tart Mold with a circle of dough.

Step 7

Bake at 350° for 8 minutes, or until the crust is no longer glossy.

Step 8

Cool completely before removing the crust from the mold.
