Swirl chocolate and yellow cake batter together in this marble sheetcake recipe and top with a rich mocha frosting.

How to Make It

Step 1

Preheat oven to 325°. Beat butter and 1 1/2 cups sugar at medium speed with a heavy-duty electric stand mixer 4 to 5 minutes or until creamy. Add eggs, 1 at a time, beating just until blended after each addition. Beat in vanilla extract.

Step 2

Sift together flour, baking powder, and salt. Add to butter mixture alternately with half-and-half, beginning and ending with flour mixture. Beat at low speed just until blended after each addition, stopping to scrape bowl as needed.

Step 3

Spoon 1 1/4 cups batter into a 2-qt. bowl, and stir in cocoa, 3 Tbsp. hot water, and remaining 1/4 cup sugar until well blended.

Step 4

Spread remaining vanilla batter into a greased and floured 15- x 10-inch jelly-roll pan. Spoon chocolate batter onto vanilla batter in pan; gently swirl with a knife or small spatula.

Step 5

Bake at 325° for 23 to 28 minutes or until a wooden pick inserted in center comes out clean. Cool completely in pan on a wire rack (about 1 hour). Spread top of cake with Mocha Frosting.

I made this yesterday, and my husband and I were very unimpressed. The cake was way too dry. Definitely NOT a "keeper" recipe.

This was a hit for my son's birthday. We didn't try the Mocha frosting with it, maybe next time.

This cake was delicious and easy to make. I used it for a baby shower cake. I made two cakes and layered them with the mocha frosting in the middle. The outside was frosted with a plain vanilla buttercream. I would make this again and again!

I didnt use any frosting and I added chocolate liquor to the chocolate batter. It was delicious, soft and fluffy. I made it twice and it barely lasted both times. Tastes best warm straight out of the oven.
