My Happy Birthday America Cake (Fresh Strawberry Cake)

The base of this cake could be made from a Vanilla cake boxed mix

Simply add a cup of pureed strawberries to the mix before adding milk.

Slowly add the required amount of milk till the batter is just right. 

Because the strawberry puree is a liquid addition, you may need to add less milk than instructed on the box, to ensure the batter is not too watery.

If you would like to try a from-scratch strawberry cake recipe, here’s how I make mine:

How to make the 4th of July Flag Cake 

Now, this is the fun part- once the cake is baked, the cream cheese frosting and Cool Whip is generously spread over the cake’s surface.

You will need fresh strawberries and fresh blueberries to form the American flag.

Slice both ends of each strawberry and the rounded corners.

This never goes to waste. 

Throw these extras (minus the leaves, of course!) into a smoothie or yogurt parfait.

Next thinly slice the body of the strawberry.

This is what you will use to form the flag.

I enlisted my 8-year-old to decorate the cake 

and I think she did a fantastic job!

I’ve been asked if one could use frozen strawberries and blueberries.

I would advise using fresh strawberries and blueberries only as frozen berries get mushy. Happy Birthday America Cake An Easy 4th of July Flag Cake!

You could also swap out the strawberries with raspberries or do a mix, alternating strawberry, and raspberry stripes.


  1. Not a fan of blueberries, but they make the cake! Strawberries and cake sound delicious.

  2. Oooooh that looks so good! I’ll definitely have to try this.

    Thank you! 🙂
