In a large mixing bowl, combine the warm water, sugar, and kosher salt. Sprinkle the yeast on top and let it sit for 5 minutes until it becomes foamy.

Add the flour and melted butter to the mixture and stir until a dough forms. Knead the dough on a floured surface for 5-7 minutes until it becomes smooth.

Place the dough in a greased bowl, cover it with a damp towel, and let it rise for 1 hour.

Preheat the oven to 450°F and line a baking sheet with parchment paper.

In a large pot, bring 10 cups of water and baking soda to a boil.

Divide the dough into 12 equal pieces and roll each piece into a long rope. Shape the dough into a Mickey Mouse head by making a circle for the head and two smaller circles for the ears.

Carefully drop each pretzel into the boiling water mixture for 30 seconds on each side. Remove with a slotted spoon and place on the prepared baking sheet.

Brush each pretzel with beaten egg and sprinkle with coarse salt.

Bake the pretzels for 12-15 minutes until golden brown.

Let the pretzels cool for a few minutes before serving.
