Authentic St. Louis Gooey Butter Cake - cooking recipe

Ingredients

Dough
1/4 cup granulated sugar
1/4 cup shortening (I use Crisco)
1/4 teaspoon salt
1 large egg
1 (1/4 ounce) envelope dry yeast
1/2 cup warm milk
2 1/2 cups all-purpose flour
1 tablespoon vanilla extract
Gooey Butter
2 1/2 cups granulated sugar
1 cup butter, softened
1/8 teaspoon salt
1 large egg
1/4 cup light corn syrup
2 1/4 cups all-purpose flour
1/4 cup water
1 tablespoon vanilla extract
powdered sugar (to garnish)

Preparation

For Dough:
In large bowl cream sugar, shortening and salt until light and fluffy.
Add egg and beat well 1 minute until well blended.
Dissolve yeast in the warm milk.
Add flour, then milk-yeast mix and the vanilla to the sugar mixture.
Mix 3 minutes. (Use dough hook if possible).
Turn dough onto lightly floured board and knead 1 minute.
Place in a lightly greased bowl and cover with a towel.
Set in a warm place to rise for 1 hour.
Than divide dough into 2 equal pieces.
Pat (or use a rolling pin)each half into a circle about the size of the cake pan. (I usually use two 9\" cake pans. Springform pans can also be used.).
Transfer dough to each pan and pat up the sides so the gooey butter doesn't run underneath.
Prick a few times with a fork to keep from bubbling up during baking.
For gooey butter:
In large bowl, combine sugar, butter and salt.
Add egg and corn syrup.
Mix enough to blend well.
Add the flour, water and vanilla, mixing well.
Divide the gooey butter in 2 equal parts.
Spread over dough in each pan.
Let stand for 20 minutes.
While cakes are standing, preheat oven to 375 degrees F (190 C).
Bake for 20 to 25 minutes, until topping starts to turn golden.
Do not over bake or the topping will not be gooey.
Let cakes cool completely on wire rack.
Sprinkle with powdered sugar if desired.
Serve at room temperature and store uneaten cakes in fridge.
