Leave the butter at room temperature to soften beforehand.
Beat the softened butter into the cream with the sugar and vanilla.
Add the egg to the mixture.
Beat everything with a mixer.
Pour the flour and baking powder.
Mix the ingredients until the dough becomes thick and has a uniform texture.
Grease a baking pan with a little melted butter.
Pour the dough into the waffle molds. Level the surface of the dough with a cooking spatula or bread knife—both tools have a flat surface suitable for this purpose.
Place the mold filled with dough on the oven rack.
Bake the waffles for 20-25 minutes, setting the heating mode to 190 degrees.
Remove the waffles from the mold, place them on a plate, and drizzle with condensed milk, jam, or any other sweet sauce.
Each wafer can be cut lengthwise, spread with boiled condensed milk or jam.
The filled Viennese waffles are ready. The perfect accompaniment to these waffles is milk or fresh tea.
