Glazed chocolate cake

Ingredients
1 1/2 cups cocoa powder
1 cup chocolate glaze (1 cup cocoa powder, 1/2 cup milk, 1/4 tsp. vanilla extract, 1 cup powdered sugar)
1 1/2 cups milk
1 cup (2 sticks) softened butter
3 cups self-rising flour
2 cups sugar
3 large eggs
1 tsp. vanilla extract
3 cups self rising flour

Directions
In a large bowl, mix the butter, sugar, eggs, and vanilla extract.  Beat mixture until fluffy.  Then add the flour and the cocoa powder.  Beat until well-incorporated.  Pour into a lightly greased and flour  two 8" or 9" pans.  Bake in a preheated 325 degree oven for 30-45 minutes.  After that time period, poke the center of the cake with a butter knife or toothpick.  If the butter knife or toothpick comes out clean, then it is ready.  Cool at room temperature for 20-30 minutes.  Then frost cake with chocolate frosting.  After cake is frosted, make the chocolate glaze in a smaller bowl.  Mix the cocoa powder, vanilla extract, powdered sugar and milk until well-incorporated.  Slowly pour glaze over cake.  Then finally, serve cake.  Makes about 12 servings.
