Jake's Birthday Cake

This is Jake's favorite cake in the world - for best results I always double the filling and the glaze!

THE CHOCOLATE CAKE
2 cups all-purpose flour
1 cup dark brown sugar (packed)
1/2 cup granulated sugar
3 teaspoons baking powder
1 teaspoon salt
1/2 teaspoon baking soda
1/2 cup shortening
1/4 cups milk
3 eggs (1/2 to 2/3 cup)
1/2 cup semisweet chocolate pieces, finely chopped (in food processor)
1/2 teaspoons vanilla
1/4 cup finely chopped walnuts (for obvious reasons, we don't use these)

Heat oven to 350 deg. Grease and flour 2 round layer pans, 8 or 9x1.5 inches (I put parchment paper in the bottom of the pan, only grease the paper, don't grease the sides). Measure all ingredients except filling, walnuts and glaze into a large mixer bowl. Blend 1/2 minute on low speed, scraping bowl constantly. Beat 3 minutes high speed, scraping bowl constantly. Pour into pans.

Bake 40 to 45 minutes or until wooden pick inserted in center comes out clean. Cool. Fill layers with Butterscotch Filling, sprinkling nuts over filling. Spread Chocolate Chip Glaze over the top of the cake.

BUTTERSCOTCH FILLING
1/2 cup light brown sugar (packed)
1/4 cup cornstarch
1/4 teaspoon salt
1/2 cup water
1 tablespoon butter

Stir together sugar, cornstarch and salt. Stir in water. Cook, stirring constantly, until mixture thickens and boils. Boil and stir 1 minute. Blend in butter. Cool.

CHOCOLATE CHIP GLAZE
1/2 cup semisweet chocolate pieces
2 tablespoons butter
1 tablespoon light corn syrup

Heat all ingredients over low heat, stirring constantly, until chocolate is melter. Cool slightly.
