My Chocolate Chip Sheet Cake is a soft and fluffy snack cake that can be served right in the pan it’s baked in. Simple to make and impossible to resist, you’ll love this perfectly sweetened cake with its simple buttercream frosting and plenty of chocolate chips! Recipe includes a how-to video!
A Simple Snack Cake
This quick and easy chocolate chip sheet cake is ideal for those of you who don’t have the time (or patience, or skills 🙋🏼♀️) for a multi-level or tiered cake recipe. For those of you who are looking for something simple but still delicious, low-maintenance but still guaranteed to have your guests asking for seconds.
While its base of the cake is similar to my (more complicated and more prettily-decorated) Chantilly cake, today’s recipe comes together much, much faster and is iced with a simple buttercream frosting, no crumb coats or piping tips required.
Let’s get to it!
What You Need
- Sugar. I chose to use granulated sugar only in this cake because I wanted to give it a lighter, whiter color that would contrast nicely against the chocolate chips. Brown sugar would have darkened the cake color a bit more than I wanted (and we’re already yellowing it some with the butter, vanilla, and egg).
- Butter. Only one stick of butter goes into the cake, then you’ll need another two for the frosting. As with most of my recipes, I always recommend using unsalted butter and then adding the salt, that way we maintain control over the flavor.
- Buttermilk. This reacts with our baking soda to give the cake some lift, but more importantly it adds tenderness, moisture, and flavor to the cake. If you don’t have buttermilk, you can use my easy buttermilk substitute.
- Mini chocolate chips. You could substitute regular-sized semisweet chocolate chips, but personally I prefer to use the smaller chips. Since our cake layer is so thin, the mini chocolate chips lend themselves to a better, less over-whelming texture, and they just look better.
SAM’S TIP: In the photos, I make this cake with a vanilla frosting. It provides a nice contrast agains the black chocolate chips on top. However, if you’d like to do a chocolate frosting instead (which I did in the video), simply mix ½ cup of cocoa powder into the frosting.

How to Make Chocolate Chip Sheet Cake
- Prepare your batter! This is a simple batter, made by first creaming together the wet ingredients with an electric mixer and then folding in the dry ingredients by hand, using a spatula. Once you’ve added the dry ingredients, it’s very important that you don’t over-mix the batter or the cake will be dense and dry. Once my batter is 75% of the way combined and most (but not all) of the flour is absorbed (shown in photo 1 above), I like to add the chocolate chips and stir until everything is completely combined (without overdoing it!).
- Spread the batter evenly into a lightly greased jelly roll pan.
- Bake until the edges are beginning to turn light golden brown and a toothpick inserted in the center comes out clean or with moist crumbs.
- Once the cake has cooled, spread frosting evenly over the surface and then sprinkle with additional chocolate chips.
SAM’S TIP: The cake batter is fairly thick, this is normal and expected. I found that a thicker batter was necessary to keep the chocolate chips suspended in the cake.
Frequently Asked Questions
Absolutely! I went with a simple and fuss-free buttercream frosting, but feel free to substitute any of my frosting recipes. Cream cheese frosting is a great option for those of you who like a less-sweet icing!
While I provide instructions in the recipe to make the frosting chocolate, I do not have advice on making the cake into a chocolate version. Unfortunately, simply adding cocoa powder would not work well here as it would most likely dry out the cake, and you would no longer be able to easily see the chocolate chips that give this cake its name.
There are two main reasons why this would happen (assuming that none of the ingredients were accidentally mis-measured and that the oven temperature is correct, which unfortunately it often is not).
1) If the cake batter was mixed too much, the cake will be both dense and dry. Never use an electric mixer to combine the wet ingredients! Instead, do this step gently by hand.
2) If the cake was over-baked, even one or two minutes too long, the cake could be dry. Many ovens are not properly calibrated, so make sure your oven’s temperature is correct and if you’re worried, check on the cake earlier than indicated in the recipe!

Chocolate Chip Sheet Cake
- 8 Tablespoons unsalted butter softened and cut into 8 pieces (113g)
- 1 ¼ cups granulated sugar (250g)
- 1 large egg room temperature preferred
- 2 teaspoons vanilla extract
- 1 ¼ cup buttermilk (295ml)
- 2 cups all-purpose flour (250g)
- 1 ½ teaspoons baking powder
- ¼ teaspoon baking soda
- ¾ teaspoon salt
- 1 cup mini chocolate chips (170g)
- Preheat oven to 350F (175C) and spray a 10×15” (25x38cm) jelly roll pan with baking spray (or lightly grease and flour). Set aside.
- In a large bowl, combine butter and sugar and use an electric mixer to beat until well-combined.
- Add egg and vanilla extract and mix well.
- With mixer on low-speed, slowly mix in buttermilk until completely combined.
- In a separate, medium-sized bowl, whisk together flour, baking soda, baking powder, and salt.
- Add the dry ingredients to the wet ingredients and use a spatula to gently fold together until batter is approximately 75% of the way combined (do not use an electric mixer for this step or you will over-mix your batter and the cake will be dense and dry).
- Add mini chocolate chips and stir until chips are distributed and batter is completely combined.
- Spread batter evenly into prepared baking pan. The batter will be thick, this is expected and necessary to keep the chocolate chips from sinking in the cake as it bakes.
- Transfer to 350F (175C) preheated oven and bake for 25-30 minutes or a toothpick inserted in the center of the cake comes out clean or with moist crumbs.
- Allow to cool completely in pan before covering with frosting.
- Place butter in a large bowl and use an electric mixer to beat until creamy.
- Gradually add powdered sugar, stirring until combined.
- Add vanilla extract, salt, and 1 Tablespoon of heavy cream and beat until thoroughly combined (be sure to scrape the sides and bottom of the bowl).
- Check consistency and add additional heavy cream if frosting is too thick to easily spread.
- If you would like to make this a chocolate frosting, add cocoa powder here and stir until combined (most likely you will need at least an additional tablespoon of cream).
- Spread over completely cooled cake. Sprinkle with remaining chocolate chips.
- Cut cake and serve directly from the jelly roll pan. Enjoy!
