My Aunt, Lorene, in Texas taught me to make this cake when I was a teenager. It is so easy and So good. It can be served plain or with a glaze. I will provide you with the Glaze I use.
This cake has sold for $250.00 at a cake auction. The buyer said it was worth every penny! You can definitely beat that price!
Preheat oven to 300 degrees. Prepare, tube or Bundt pan by generously greasing and flouring it.
In large mixing bowl mix cake mix and dry pudding mix together.
Add water, oil and eggs (one at a time, beating after each addition). After everything is added, beat 1 minute longer.
Reserve 1 cup of the batter, and pour the rest of the batter into the prepared pan.
Melt the chocolate in the microwave, 30 seconds at a time. When melted, stir into reserved batter.
Drizzle over top of cake batter and, with a butter knife, swirl into cake batter.
Bake at 300 for 1 hour-1 hour 15 minutes. Depends on your oven. Test with toothpick or cake tester and when it comes out clean it's done.
Cool cake and when cool drizzle the glaze over the cake. Glaze instructions are below.
Melt the chocolate squares in microwave, 30 seconds and stirring after each time until smooth. Then beat in butter a little at a time. Stir in corn syrup. Let glaze cool a bit to thicken slightly. Drizzle over cake. If glaze holds it's shape it's too thick. Reheat at 15 second intervals until thin enough.
Note: I have substituted semi sweet chocolate chips using 1 1/3 cups of chips for the recipe. Worked fine.
