Preheat your oven to 350°F (175°C). In a large bowl, mix the flour, sugar, and vanilla powder.

Add the softened butter and milk, stirring until the batter is smooth.

Divide the batter into three portions. Leave one portion plain, add red food coloring to the second, and blue to the third. Mix well.

Pour the batter into a greased baking dish and bake for 25-30 minutes, or until a toothpick comes out clean.

Let it cool, then top with whipped cream, strawberries, and blueberries for a patriotic look.
