In a bowl, mix 1 cup of warm water (110°F), 1 tablespoon of granulated sugar, and 2 teaspoons of active dry yeast. Allow the mixture to froth for about 5-10 minutes until bubbly. Next, add 2 tablespoons of melted unsalted butter and 1 teaspoon of salt, stirring well. Gradually incorporate 3 cups of all-purpose flour until a dough forms, then knead for 5-7 minutes until smooth and elastic. Place the dough in a greased bowl, cover, and let it rise for 1 hour until doubled in size.

While your dough rises, combine 1 cup of shredded cheddar cheese, 4 ounces of softened cream cheese, ½ teaspoon of garlic powder, and ½ teaspoon of onion powder in a mixing bowl. Season with salt and pepper to taste, ensuring the mixture is well-blended and creamy. Set the cheese mixture aside, as this will be the savory filling for your Cheese Stuffed Pretzels.

Once the dough has risen, punch it down gently and divide it into 12 equal pieces. Roll each piece into a rope about 12 inches long, then flatten it slightly. Spoon about a tablespoon of the cheese filling along the center, fold the dough over the filling, and pinch the edges to seal tightly. Shape each filled dough piece into a pretzel knot and place them on a parchment-lined baking sheet.

In a large pot, bring 10 cups of water to a boil, then carefully stir in ⅔ cup of baking soda, reducing the heat to a simmer. This pretzel bath gives your Cheese Stuffed Pretzels that classic chewy texture. Keep the pot at a simmer and be ready for boiling each pretzel for their special treatment.

Using a slotted spoon, gently lower each pretzel into the simmering water, boiling for about 30 seconds on each side. Once boiled, carefully lift them out and place them back on the parchment-lined baking sheet. This step not only enhances the texture but also starts developing that beautiful golden-brown color.

Preheat your oven to 425°F (220°C). Before baking, brush each pretzel with a beaten egg for a shiny finish, then sprinkle coarse sea salt on top for added flavor. Slide the baking sheet into the oven and bake for 12-15 minutes, or until the pretzels turn a lovely golden brown. This final step creates the perfect crust while sealing in the cheesy goodness within.
