Preheat the oven to 350º F. Spray a cookie sheet with cooking spray.

In a small bowl, combine 1 cup flour and 1/2 cup softened butter (1 stick) until crumbly. Add1 Tbsp. cold water. Form into 2 balls and pat into two 3-inch strips on cookie sheet.

Bring 1 cup water and 1/2 cup butter to a boil. Add 2/3 cup flour. Mix until smooth. Add 3 beaten eggs and 1/2 tsp. almond flavoring and combine. Spread onto two crusts all the way to the edges. Bake for 1 hour.

Cool your pastry and make your frosting. Combine soft butter, powdered sugar, almond flavoring and water. Add more powdered sugar if needed to get right consistency. Spread on cooled pastry. Cut into slices and enjoy!
