In a blender, combine 3 large eggs, 1/2 cup all-purpose flour, 1/3 cup whole milk, 1/3 cup half-and-half, 1 tablespoon vanilla sugar, 1 teaspoon vanilla extract, 1/4 teaspoon salt, 1/4 teaspoon nutmeg, 1/4 teaspoon cinnamon. Blend for around 30 seconds on high speed until you have a smooth batter. Make sure to scrape the sides of the blender once to incorporate all flour properly.
