Ingredients in Chocolate Chip Sheet Cake

Here’s the sweet simplicity of it—classic ingredients, layered into something seriously crave-worthy.

All-Purpose Flour

The base of our soft, fluffy cake. It gives structure without making the crumb too dense.

Baking Powder & Baking Soda

The dynamic duo that keeps this cake beautifully risen and tender.

Salt

Just a pinch brings out the sweetness and deepens the flavor of the chocolate.

Unsalted Butter

Melted and folded right in for that rich, buttery taste we all love.

Granulated Sugar & Brown Sugar

A combo for sweetness and that hint of caramel depth from the brown sugar—totally worth it.

Eggs

They bind everything together and add moisture and richness.

Vanilla Extract

A splash of vanilla warms up all the flavors and gives the cake that homemade, nostalgic aroma.

Buttermilk

It keeps the crumb extra tender and brings a subtle tang that balances the sweetness.

Chocolate Chips

The star mix-in—those melty, gooey bites of happiness scattered throughout the cake.

Ingredients in Cookie Dough Buttercream

Now for the frosting—this is where things get outrageously good.

Unsalted Butter

Softened so it whips up creamy and dreamy.

Brown Sugar

Gives that signature cookie dough taste—caramelly, cozy, and just a little grainy in the best way.

Powdered Sugar

Smooths things out and adds the classic frosting sweetness.

Vanilla Extract

Just like in cookies, it’s a key flavor note in the frosting.

All-Purpose Flour

Lightly heat-treated and added to mimic actual cookie dough texture—trust the process.

Milk or Cream

To loosen things up and get that spreadable, cloud-like consistency.

Mini Chocolate Chips

Folded in for texture and that classic cookie dough vibe.

Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment

Start by preheating your oven to 350°F (175°C). This ensures even baking and gives your cake that golden-brown top we love.

Combine Ingredients

In a large bowl, whisk together the flour, baking powder, baking soda, and salt. In another bowl, mix the melted butter, sugars, eggs, and vanilla until smooth. Stir in the buttermilk, then gently fold in the dry ingredients and chocolate chips. Mix just until combined—don’t overdo it.

Prepare Your Cooking Vessel

Grease a 9×13-inch baking dish or line it with parchment paper. This step makes clean-up easier and ensures your cake doesn’t stick.

Assemble the Dish

Pour the batter into your prepared pan and spread it out evenly with a spatula. It should look thick and fluffy—kind of like chocolate chip cookie dough but smoother.

Cook to Perfection

Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean. The edges should be lightly golden, and the top set but soft.

Finishing Touches

Let the cake cool completely before frosting. Patience here pays off—if it’s warm, the buttercream will melt right off.

Serve and Enjoy

Spread the cookie dough buttercream generously over the cooled cake, sprinkle with mini chocolate chips, and slice into squares. Serve with cold milk or hot coffee, and just watch everyone swoon.

How to Serve Chocolate Chip Sheet Cake with Cookie Dough Buttercream

This cake is already the star, but here’s how to give it an encore:

Cut into Bars for a Party Platter: Easy to serve, easy to love.

Additional Tips

Here are some extra tips to help you get the most out of this recipe:

Use Room Temp Ingredients: They mix better and result in a smoother batter.
Don’t Skip Cooling Time: Letting the cake cool before frosting helps the buttercream stay fluffy and beautiful.
Heat-Treat Flour for Frosting: If you’re nervous about raw flour, microwave it for a minute or bake at 350°F for 5 minutes.
Store Frosted Cake in the Fridge: Keeps it fresh and helps the buttercream stay firm.
Freeze the Cake (Unfrosted): Bake ahead, freeze the cake, and frost it later for a make-ahead treat.
