How to Make Flag Cake
STEP 1. Prepare the cake batter. In a large mixing bowl, stir together the cake mix, eggs, sour cream, cold milk, and melted butter until well combined.
STEP 2. Transfer to baking dish. Pour the cake batter into a greased 9×13-inch baking dish, spreading it evenly with a spatula.
STEP 3. Bake the cake. Bake according to the package instructions, usually until a toothpick inserted in the center comes out clean.
STEP 4. Cool the cake. Allow the cake to cool completely in the baking dish after removing it from the oven.
STEP 5. Make the pudding mixture. In a separate bowl, whisk together the vanilla pudding mix and cold milk for two minutes until thickened.
STEP 6. Combine with whipped topping. Gently fold in the whipped topping into the pudding mixture until fully blended and creamy.
STEP 7. Frost the cake. Spread the whipped topping mixture evenly over the cooled cake using a spatula.
STEP 8. Decorate the cake. Outline a square in the top left corner with blueberries, filling in the square with more blueberries.
STEP 9. Create the stripes. Arrange strawberry slices in rows beneath the blueberries to form stripes; fill in gaps with shredded coconut as desired.
STEP 10. Chill before serving. Refrigerate the cake until ready to serve, allowing the flavors to meld together.

Pro Tips
For an even fluffier cake, ensure your ingredients are at room temperature before mixing. This allows for better incorporation of air into the batter. When you spread the whipped topping mixture, use a spatula dipped in warm water for a smoother finish. If you’re using fresh fruit, wash and dry them thoroughly to prevent excess moisture on the cake. To create cleaner lines with your fruit decorations, use a sharp knife to slice strawberries uniformly. If you’re short on time, a store-bought whipped topping can save you some prep work without sacrificing taste. Lastly, consider using a stand mixer for effortless mixing of your cake batter, resulting in a well-blended mixture that helps achieve that perfect fluffiness.
Common Mistakes to Avoid
One common mistake is not allowing the cake to cool completely before frosting; this can lead to melted frosting and a soggy cake. Another issue can occur if the cake is overbaked, resulting in a dry texture—keep an eye on the timer and do the toothpick test for doneness. Using instant pudding is crucial; don’t use cook & serve as it won’t create the right consistency. When arranging your toppings, be careful not to add too much moisture from washed fruits; it’s best to dry them with a paper towel first. Avoid rushing the refrigeration step; chilling the cake allows it to set well and enhances the overall flavors and presentation before serving.
Variations
• Use different fruits like raspberries or kiwi for a colorful twist.
• Make it gluten-free by using a gluten-free cake mix.
• Add a layer of lemon curd for a zesty flavor boost.
• Incorporate a flavored pudding mix like coconut for added depth.
• Use cream cheese in place of whipped topping for a richer topping.
Serving Ideas
This striking dessert pairs wonderfully with iced tea or lemonade, making it a perfect choice for outdoor events. Serve slices alongside vanilla ice cream for a delightful contrast of temperatures. For festive occasions, add decorative sprinkles to enhance the celebration atmosphere. If you’re crafting a dessert table, slice the cake into small squares for easier serving and a more appealing display. Alternatively, serve it with a dollop of extra whipped cream for added indulgence.
Meal Prep & Storage
Prepare this delightful treat a day in advance to enhance flavors and save time on the day of your gathering. After frosting and decorating the cake, cover it with plastic wrap or a lid to prevent it from absorbing any fridge odors. Store in the refrigerator for up to three days for optimal freshness. If you’re anticipating leftovers, it’s best to serve individual portions rather than the whole cake to maintain its appearance. To freeze, slice the cake into servings, place in an airtight container, and it can last up to three months. Thaw overnight in the fridge for the best texture when ready to enjoy again.
