Chocolate Sheet Cake: Perfect Dessert for a Gathering!

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.”

An Excess of Sweets

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 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!

  31. I love sheet cakes they are great for feeding a crowd, but like you I live in a small household and cakes this size would linger if I didn’t have friends and family to give it all away to, that or I would over eat it, especially if it was this chocolate cake 😀

  32. def a crowd pleaser!! Esp for this chocoholic!

  33. I never pass up chocolate cake and this one looks amazing. Since it’s a sheet cake…. it’s not two layer so I don’t have to feel so guilty eating a piece. 🙂 Then again, I would probably want two pieces. 😉

  34. Lizzy,
    I hadn’t seen this post but I made this very same cake from the Pioneer Woman today. I’m having my family over for my Sister’s birthday tomorrow. How funny is that?!? 🙂

  35. My dessert loving crew will arrive next month and this will be perfect. I may have to make two!

  36. Beautiful and delicious cake 🙂
    Would be a hit with my family!
