In a stand mixer, combine ¼ cup warm water and 2 teaspoons active dry yeast. Let it sit for 10–15 minutes until the yeast dissolves.
Add 1 cup milk, 4 tablespoons melted butter, ? cup sugar, 1 large egg, and 1 teaspoon salt to the mixer. Mix using the dough hook for about 1 minute until combined.
Gradually add 3 ½ to 4 cups flour, 1 cup at a time, mixing after each addition until a soft dough forms. The dough is ready when it pulls away from the sides of the bowl.
Place the dough in a lightly oiled bowl, cover with plastic wrap or a damp cloth, and let rise for 1–2 hours until doubled in size.
Punch down the dough and roll it out on a floured surface to about ½ inch thick.
Cut into 20–24 squares using a pizza cutter.
Spray 2 baking sheets with nonstick spray and place the dough squares at least 1 inch apart. Cover and let rise for 30 minutes until doubled.
Preheat the oven to 350 degrees F.
Bake for 12–15 minutes until light golden brown.
Brush the tops with the remaining 2 tablespoons melted butter, let cool slightly, and serve.
