Preheat oven to 350°F.

For the pastry, cut the butter into the flour.

Sprinkle with water and mix with a fork.

Mold the dough into a ball.

Divide in half and and pat each into a long strip (12 X 3) on an ungreased baking sheet.

Chilling for a few minutes helps keep the dough together when you pat it out.

For the filling, melt butter and water and bring to a rolling boil over medium heat.

Add the extracts and remove from heat.

Immediately stir in the flour, stirring/whisking vigorously until smooth and thick.

When smooth and thick, add the eggs one at a time, beating on low with a hand mixer after each until smooth.

Divide the mixture in half and spread evenly over each strip of pastry on the baking sheet.

Bake for 50 to 60 minutes.

The filling will be puffy and golden, but fall a bit while it cools, especially in the center.

Let cool a bit and frost each strip with your favorite butter cream or cream cheese frosting.
