Step-by-Step Instructions
- Prepare the Sheet Pan and Preheat Oven:
- Set your oven to 350 degrees Fahrenheit well before baking. Grease and line a standard half-sheet pan with parchment making sure there is overhang on each side for easy lifting. This ensures the cake bakes evenly and comes out beautiful every time.
- Sift and Mix the Dry Ingredients:
- Place flour granulated sugar baking soda cocoa powder and salt in a large bowl. Sift them together thoroughly breaking up any clumps. Whisk them until fully blended since this ensures a smooth even cake crumb.
- Whisk the Wet Ingredients:
- In a separate bowl combine the vegetable oil buttermilk eggs red food coloring white vinegar and vanilla extract. Whisk slowly at first then more vigorously until no streaks remain and the mixture looks silky and unified.
- Combine Wet and Dry Mixtures:
- Pour the wet ingredients into the dry bowl in two batches. Stir gently with a spatula just until all dry bits disappear. Scrape the bowl often and avoid overmixing to keep the cake incredibly tender.
- Pour and Bake the Cake:
- Spread the batter evenly into the prepared pan using an offset spatula to smooth the surface. Transfer to the center rack of the oven. Bake until the cake springs back to the touch and a toothpick comes out clean after about twenty to twenty-five minutes.
- Cool the Cake:
- Set the pan on a wire rack. Wait fifteen to twenty minutes until the cake firms up slightly then lift out by the parchment and let cool completely on the rack. Cooling prevents the frosting from melting and keeps the berries looking fresh.
- Make the Cream Cheese Frosting:
- In the bowl of a stand mixer beat cream cheese and butter on medium until very fluffy and light. Gradually add sifted powdered sugar vanilla and a pinch of salt. Beat until smooth. Add heavy cream in tiny amounts until you reach a creamy spreadable texture.
- Frost and Decorate:
- Spread the frosting generously over the cooled cake all the way to the edges. Decorate the top with rows or clusters of raspberries and blueberries pressing lightly so they stay secure. The vibrant berries transform the cake into a patriotic centerpiece.

Every Fourth of July my daughter helps lay the berries across the frosting in red and blue stripes. We laugh as we taste test berries together and admire our handiwork on the baking counter.
Storage Tips
This cake holds up beautifully if made one day in advance. Cover the entire pan tightly with plastic wrap and chill in the refrigerator. For longer storage cut leftovers into squares and wrap individually. The cake stays soft for up to three days and the berries remain bright and juicy.
Ingredient Substitutions
If you are out of buttermilk you can stir together plain Greek yogurt with a splash of water to mimic both tang and moisture. Melted coconut oil works well in place of vegetable oil adding a faint tropical aroma while keeping crumb ultra-soft. For a natural red hue try beet juice instead of food coloring which brings earthiness and subtle extra sweetness without artificial dyes.
Serving Suggestions
Serve this cake chilled or at cool room temperature. For parties slice into rectangles and arrange on a platter for easy grabbing. Add more varieties of fruit such as blackberries or sliced strawberries for a rainbow effect. This sheet cake makes an unforgettable centerpiece on a holiday dessert table alongside ice cream or lemonade.
