In a large saucepan, bring the water and butter to a boil. As soon as it starts to boil, take the mixture off the heat and let cool for 5 minutes.
Add this mixture to a large bowl, and combine with the flour, sugar, eggs, sour cream, vanilla, almond, salt, and baking soda. Mix just until combined, scraping the sides of the bowl as needed.
Put in a greased 10x15 inch pan in the oven for 20-22 minutes.
Once the cake is baked and cooled, use 2 cups of a whipped topping of your choice to spread onto your cake.
Use your blueberries and sliced strawberries to create the shape of the American Flag.
Store in the fridge, covered in plastic wrap, for 3-4 days.
