Texas Sheet Cake will always be one of my favorite desserts for summer cookouts and family get togethers. This marble cake is just as delicious and the rich chocolate icing makes it totally irresistible. We also love these easy Cake Mix Bars that are filled with chocolate chips and m&m’s.
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.

- 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

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.

- 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.
