I first made this cake for a summer party, and it quickly became the centerpiece dessert that people kept asking for seconds.

Instructions
- Prepare the Sheet Pan and Preheat Oven:
- Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius. Grease and line a halfsheet pan measuring about 13 by 18 inches with parchment paper this helps the cake release easily and bake evenly.
- Sift and Mix the Dry Ingredients:
- In a large mixing bowl sift together the allpurpose flour granulated sugar baking soda cocoa powder and salt. This removes lumps and ensures everything is evenly combined for a smooth batter.
- Whisk the Wet Ingredients:
- In a separate bowl whisk the vegetable oil buttermilk at room temperature eggs also at room temperature red food coloring white vinegar and vanilla extract until the mixture looks smooth and fully blended.
- Combine Wet and Dry Mixtures:
- Carefully pour the wet ingredients into the bowl with the dry ingredients. Mix gently with a spatula just until you see no more streaks of flour. Avoid overmixing to keep the cake tender.
- Pour and Bake the Cake:
- Pour the batter into your prepared sheet pan. Spread it out evenly using an offset spatula for an even bake. Bake in your preheated oven for 20 to 25 minutes. The cake is done when a toothpick inserted in the center comes out clean and when you press lightly on top it springs back.
- Cool the Cake:
- Allow the cake to cool in the pan on a wire rack for 15 to 20 minutes. Then use the parchment paper overhang to carefully lift it out of the pan. Let it cool completely on the rack before frosting to avoid melting.
- Make the Cream Cheese Frosting:
- Beat the softened cream cheese and butter together in a mixer until the mixture is light and fluffy. Gradually add the sifted powdered sugar along with the vanilla extract and a pinch of salt. Mix until smooth. Add 1 to 2 tablespoons of heavy cream to adjust the frosting to a silky spreadable consistency.
- Frost and Decorate:
- Spread the cream cheese frosting evenly over the cooled cake using a spatula. Gently place fresh raspberries and blueberries across the top spacing them evenly for a festive and vibrant finish.

I love using fresh berries on this cake because they bring both color and a crisp freshness to the rich and sweet cake. One summer when I made this for a picnic it was the star of the dessert table with everyone marveling at how the tart raspberries brightened every bite.
Storage Tips
Store the cake covered tightly in the refrigerator to keep the frosting fresh and prevent the berries from drying out. It’s best enjoyed within 3 days. You can also slice and freeze leftovers individually wrapped for up to 2 months.
Ingredient Substitutions
