Waffle Tubes with Dulce de Leche

Whisk together eggs, sugar, and salt.

Mix flour with cornstarch and vanilla.

Pour in melted margarine or butter (make sure it's not hot).

Gradually add the flour mixture to the eggs, stirring well until there are no lumps.

The batter should have the consistency of sour cream—a bit thicker than crepe batter.

Heat up your waffle iron and lightly oil the surface. Pour 2 tablespoons of batter into the center (adjust the amount depending on the size you want).

Press down gently.

Bake until golden and crispy (they cook very quickly).

Roll the hot waffles into tubes right away, whatever way works best for you.

Fill the tubes with dulce de leche using a pastry bag, piping bag, or just a teaspoon, depending on the shape.
