How to Make Flag Cake Recipe
Let’s dive into the steps to create this beautiful cake!
Step 1: Prepare the Cake
- Preheat your oven to 350°F (175°C). Grease and flour a rectangular cake pan (about 13×18 inches).
- In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Add the eggs one at a time, mixing well after each addition.
- Stir in the vanilla extract.
- In another bowl, combine the flour, baking powder, and salt. Gradually add this dry mixture to the wet mixture, alternating with the milk. Mix until just combined.
- Pour the batter into the prepared cake pan and spread it evenly.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan.
Step 2: Make the Frosting
- In a large mixing bowl, beat the softened butter with an electric mixer until creamy.
- Gradually add the powdered sugar, alternating with milk, and mix until smooth and fluffy.
- Add the vanilla extract and continue to beat until well combined.
Step 3: Assemble the Cake
- Once the cake has cooled, spread a generous layer of frosting over the top.
- Use red food coloring to create stripes with the frosting. You can use a piping bag for precision.
- In the top left corner, create a blue rectangle using frosting and then add fresh blueberries to represent stars.
- Arrange the sliced strawberries in rows to create the red stripes.
Step 4: Serve
- Slice the cake into squares and serve with whipped cream if desired. Enjoy your festive Flag Cake!
Substitutions & Additions
If you’re looking to mix things up a bit, consider these fun ideas:
- Use almond extract instead of vanilla for a different flavor twist.
- Swap out the berries for other fruits like raspberries or blackberries.
- Add a layer of cream cheese frosting for an extra creamy texture.
Tips for Success
Here are some common mistakes to avoid and prep-ahead ideas:
- Make sure your butter is softened, not melted, for the best frosting texture.
- Don’t overmix the batter; it should be just combined to keep the cake light.
- You can bake the cake a day ahead and frost it just before serving for convenience.
How to Store Flag Cake Recipe
To keep your delicious Flag Cake fresh:
- Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
