Marble Sheet Cake with Chocolate Sour Cream Frosting
Sheet cakes are my favorite because they are so easy to make and don’t require special skills for decorating. They are always a hit and perfect to feed a crowd. I am taking a shortcut with using a yellow cake mix to make this recipe a bit easier.
Ingredients Needed:
For the Cake:
- Yellow Cake Mix ~ White cake mix works too.
- Large Eggs ~ Room temperature
- Butter ~ Softened or vegetable oil
- Milk ~ Whole milk works best
- Semi- Sweet Chocolate Chips ~ Milk chocolate will work too
- Sour Cream
For the Frosting:
- Semi- Sweet Chocolate Chips ~ or milk chocolate
- Butter ~ Room temperature
- Sour Cream
- Vanilla Extract
- Powdered Sugar
How to Make Marble Sheet Cake:
- Butter a jelly roll pan using the butter wrapper or non-stick cooking spray. Set aside.
- Add cake mix, eggs, softened butter and milk to a mixer bowl. Beat at low speed for 1 minute, raise to medium speed and beat 2 minutes. Scrape down the sides and bottom of the bowl and beat another 30 seconds.
- Reserve 1 1/2 cups cake batter. Pour the remaining batter into the prepared pan, spreading evenly.
- Melt chocolate chips with sour cream over low heat just until chips are melted and smooth, or in the microwave in 30 second intervals, stirring in between.
- Combine the melted chocolate with reserved cake batter with a whisk until smooth.
- Dollop chocolate batter into the pan.
- Use a butter knife to swirl the chocolate batter into the yellow cake batter.
- Bake for about 18- 20 minutes.
- Remove to a wire rack to cool completely.
Make the Frosting:
- Melt chocolate chips with butter over low heat in a small pan or in the microwave in a microwave safe bowl in 30 second intervals, until chocolate is melted and smooth.

- Mix on low until powdered sugar is incorporated and then on medium-high for 1-2 minutes to whip the frosting.

Recipe Notes:
- Yield: 12 Servings
- Frosting: The chocolate sour cream frosting pairs perfectly with this marble cake. It’s thick and rich with just a hint of tangy flavor from the sour cream. It spreads easily over the cake and can be used for cupcakes too.
- Garnish: Sliced strawberries compliment the chocolate icing. Chocolate curls or chocolate jimmies are great options too if you want to add garnish.
- Storage: Store cake at room temperature covered with plastic wrap up to 4 days. Store in refrigerator up to 6 days.
- Freeze: Cake without frosting can be wrapped in 2 layers of plastic wrap and a layer of foil and frozen up to 3 months. Thaw at room temperature.
- Jelly Roll Pan: This is the 10 x 15 inch pan that I use, it’s a bit smaller than a half-cookie sheet and perfect for sheet cakes.
- Occasions: Cookouts and potlucks, holiday dinners like Easter, 4th of July, Thanksgiving and Christmas.
