Yummy Birthday Cake

Here's a delicious, mouth-watering recipe I got from my friend Deb.

Yummy Birthday Cake
1 chocolate cake mix (with ingredients to make it)
2 cups heavy cream
½ tsp cream of tartar
8 ounces cream cheese
1 tsp vanilla
¾ cup brown sugar
2 - 1 ounce bars semi-sweet chocolate
Hershey’s candy bar

Make 1 chocolate cake mix, using two 8 inch or 9 inch pans, according to the directions on the box. You can use any type of chocolate cake—milk, dark, devil’s food, etc. When the cakes are completely cool, slice them in half horizontally.
Frosting: In large bowl, beat heavy cream on high speed until stiff. Beat in cream of tartar just until blended.
In separate bowl, beat cream cheese, vanilla, and brown sugar until fluffy. Cut 2 bars of semisweet chocolate (the kind that comes in a box in the baking section) into chunks (about ½ cup). Stir chunked chocolate into cream cheese mixture. Fold this into the heavy cream.
Put the cake together, layering the 4 sections with frosting between each one, and then frost the whole outside of the cake.
Grate a regular-sized Hershey bar on top of the cake and on the plate around the cake, if there’s room. It’s best to make this ahead of time and let it “set” in the refrigerator for several hours or overnight.
