For the Waffles:

Cup of Yum
1. To make the waffle dough, in a small saucepan, bring the milk to a lukewarm temperature over medium-low heat and stir in the yeast to dissolve. Let sit for at least 10 minutes, until foamy.
2. In a large mixing bowl, combine the flour, salt, sugar, eggs, and milky yeast. Mix until just incorporated.
3. Add the butter in small additions, continuously kneading until the butter is fully incorporated.
4. Cover the bowl with a kitchen cloth and let sit in a dry environment for at least 2 hours or until doubled in size.
5. After 2 hours, shape the dough into 20 to 22 balls (about 25 grams each). Place them on a tray, cover with a kitchen cloth, and let sit for 1 hour.

To make the Filling:

1. Meanwhile, make the filling. In a medium bowl, combine the sugar and melted butter until creamy.
2. Grease and heat a thin waffle iron. Place one dough ball in the iron, and bake until golden, about 2 minutes.
3. Working quickly, remove the waffle from the iron, cut in half horizontally, smear the inside with a generous dollop of the filling and close the two halves. Repeat with the rest of the balls.
4. Enjoy warm or cool.
