Abbi’s Sheet Cake

For the cake:
Sift the sugar and flour into a large bowl. Set aside.

Add water, margarine, oil and cocoa powder into a saucepan. Bring to a boil and then pour it over the dry ingredients, mixing well. Set aside.

In a small bowl, mix together buttermilk, eggs and vanilla. Then add this into the chocolate batter and stir rapidly to combine.

Pour batter into a greased and floured 11×16 sheet pan. Bake at 350 F for 15 to 18 minutes.

Start preparing the chocolate icing (instructions below) about 5 minutes before cake is done. When cake is done, remove it from the oven and frost cake in the pan.

Icing:
Place margarine, cocoa and milk into a saucepan. Bring to a slow boil being careful not to let it scorch. Once it boils, remove it from the heat and add confectioners’ sugar and vanilla extract. Spread over the hot cake.
