Chocolate Sheet Cake

A sheet cake is always an excellent selection for serving a group of chocolate lovers. Batter is poured into a half-sheet pan, baked and then a glossy, fudgy icing is poured over the warm cake for the crowning glory. The motto at our house is that “frosting makes any dessert even better.”

Easy Dessert for a Crowd

With only 3 of us living in our house except for college breaks, the desserts around here don’t disappear very fast. But I know which friends and neighbors love what. They are delighted to receive my surplus of sweets.

Steve across the street gets samples of my cheesecakes and Mark around the corner has volunteered to take any chocolate cast offs. I packaged up about 4 slices of this chocolate sheet cake for Mark and his wife. When they had unexpected company that night, Jeanne plated the slices of the cake and served her guests. She graciously thanked them when they praised her wonderful recipe.

It was only the next day when she received a phone call requesting a copy of said recipe, that she fessed up. Now it’s available for all of you to try–your taste testers will want the recipe, too! Save this recipe for chocolate sheet cake for when you have casual entertaining needs, and share any leftovers with friends and family!
