The beauty of this cake lies in its straightforward ingredients—each thoughtfully chosen to deliver the perfect flavor, texture, and richness. From the creamy butter and smooth oil that create moistness, to the buttermilk adding a subtle tang and tenderness, every component matters.

Unsalted butter (⅓ cup + ½ cup): Using room temperature butter ensures a creamy batter and smooth frosting texture.
White sugar (1⅔ cup): Sweetens the cake and helps with the tender crumb and slight caramel notes.
Neutral oil (¼ cup): Adds moistness without overpowering flavors, keeping the texture soft.
Large eggs (4): Provide structure and richness, best used at room temperature for even mixing.
Vanilla extract (3 teaspoons): Enhances overall flavor with warm and aromatic undertones.
Baking powder (2 teaspoons): Helps the cake rise perfectly, giving it a light lift.
Kosher salt (1½ teaspoons + pinch): Balances sweetness and enhances all chocolate flavors.
All-purpose flour (3 cups): Forms the base, providing structure and a tender crumb.
Buttermilk (½ cup): Adds moisture and a gentle tang that elevates the cake’s flavor.
Mini chocolate chips (1 cup): Tiny pockets of melted chocolate dispersed throughout the batter for delightful texture.
Semisweet chocolate (3 oz, chopped): Melted into the frosting for an indulgent, fudgy finish.
Confectioners’ sugar (1 cup): Sweetens and smooths the frosting, giving it the perfect consistency.
Dutch-processed cocoa powder (½ cup): Provides a deep, rich chocolate flavor with a smooth finish.
Sour cream (¼ cup): Adds creaminess and tang to balance the sweetness of the frosting.

How to Make Chip Sheet Cake with Chocolate Fudge Frosting Recipe

Step 1: Prep Your Pan and Preheat the Oven

To begin, set your oven to 350℉ (175℃). Prepare a 9×13-inch cake pan by greasing it and lining it with parchment paper. This helps the cake release effortlessly once baked, and guarantees clean edges for perfect slices.

Step 2: Cream Butter, Oil, and Sugar

In a stand mixer fitted with the paddle attachment, beat the room temperature butter with oil and sugar until creamy on medium speed. This process takes around 2-3 minutes and creates a fluffy base that gives the cake its wonderful light texture. Don’t worry if it looks slightly grainy at this point; that’s exactly what you want.

Step 3: Add Eggs and Vanilla

Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl so everything becomes well incorporated. Then stir in the vanilla extract – its aroma is truly the hallmark of a comforting chocolate cake.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking powder, and kosher salt. This dry mix is the structural foundation that will give your cake the right rise and texture.

Step 5: Alternate Adding Dry Ingredients and Buttermilk

Add one-third of the flour mixture to the wet ingredients and mix on low speed until just combined. Follow with half of the buttermilk. Repeat the process one more time—flour, then buttermilk—before finishing with the remaining flour mixture. This alternating method ensures a batter that is smooth, tender, and perfectly hydrated.

Step 6: Fold in Mini Chocolate Chips

Gently fold the mini chocolate chips into the batter with a spatula. These chips will melt slightly during baking, creating those signature delightful chocolate pockets so beloved in this recipe.

Step 7: Bake the Cake

Pour the batter into your prepared pan. Bake for 33 to 42 minutes, or until a toothpick inserted in the center comes out clean. When done, allow the cake to cool in the pan for 10-15 minutes before transferring onto a wire rack to cool completely.

Step 8: Melt Chocolate for the Frosting

Place chopped semisweet chocolate in a microwave-safe bowl and melt in short bursts of 10-15 seconds, stirring between each to prevent burning. Set aside once fully melted and glossy.

Step 9: Make the Chocolate Fudge Frosting

In the mixer, beat the butter and confectioners’ sugar on low until combined. Gradually increase speed to medium-high and beat until light and fluffy. Add Dutch-processed cocoa powder and mix on low until just combined, then beat on medium for another 1-2 minutes. Scrape down the sides to incorporate every bit of that luscious frosting.

Step 10: Finalize Frosting and Assemble

Mix in sour cream, melted chocolate, and a pinch of kosher salt. Once the frosting becomes glossy and smooth, spread it generously over the completely cooled cake. Now, step back and admire your masterpiece before diving in!

Garnishes

Adding a simple garnish can elevate this cake visually and taste-wise. Sprinkle a handful of mini chocolate chips or shave some dark chocolate curls over the top. A dusting of cocoa powder or a few edible gold flakes can bring a touch of elegance. Fresh raspberries or strawberries on the side will add a pop of color and a gentle tart counterpoint to the rich chocolate.

Side Dishes

This cake pairs wonderfully with light and fresh companions. Consider serving with a scoop of vanilla bean ice cream, which adds creamy coolness that balances the fudge frosting’s richness. A dollop of freshly whipped cream or a side of fresh fruit salad can make your dessert feel complete without overwhelming the chocolatey glory.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

You can keep the leftover cake covered tightly at room temperature for up to two days. For longer storage, wrap it in plastic wrap and place it in an airtight container in the refrigerator. This helps maintain the moistness of the cake and the softness of the chocolate fudge frosting without it becoming overly hard.

Freezing

This Chip Sheet Cake with Chocolate Fudge Frosting Recipe freezes beautifully. To freeze, wrap individual slices or the whole cake tightly in plastic wrap, then add a layer of aluminum foil on top. It will keep well for up to three months. When ready to enjoy, thaw overnight in the refrigerator to preserve texture and flavor.

Reheating

If you prefer your cake slightly warmed, pop a slice in the microwave for about 15 to 20 seconds. This will soften the fudge frosting and bring out the richness in the chocolate chips, making every bite feel freshly made.

FAQs

Can I use regular chocolate chips instead of mini chocolate chips?

Absolutely! Regular chocolate chips will work just fine. The mini chips distribute a bit more evenly throughout the cake, but feel free to use whatever you have on hand.

Is there a way to make this cake dairy-free?

You can substitute the butter with a dairy-free margarine or coconut oil, and use a plant-based milk with a splash of vinegar instead of buttermilk. Keep in mind the frosting may need adjustments to maintain its creamy texture.

Can I bake this cake in smaller pans or cupcakes?

Yes, you can! Just reduce the baking time and keep an eye on the texture. Cupcakes might take around 18-22 minutes at the same temperature. The flavors will be just as wonderful.

Why does the recipe call for both butter and oil?

Using a combination of butter and oil provides the best of both worlds: butter adds flavor and richness, while oil keeps the cake moist and tender. This blend helps create that perfect texture everyone loves.

How do I know when the cake is fully baked?

The best test is inserting a toothpick or clean knife in the center—if it comes out clean or with a few crumbs attached, the cake is done. Avoid overbaking to keep the cake moist.
