Begin by gently heating your Nutella in a microwave-safe bowl for about 20-30 seconds, or until it becomes pourable. Stir it to achieve a smooth consistency. Set aside the warm Nutella.

In a medium saucepan over medium heat, combine 1 cup of water, 1/2 cup of unsalted butter, 1 teaspoon of salt, and 1/4 cup of granulated sugar. Bring this mixture to a boil while stirring to dissolve the sugar.

Remove the saucepan from heat, and quickly stir in 1 cup of all-purpose flour. Use a wooden spoon to mix vigorously until the dough forms a ball, pulling away from the sides of the pan.

Allow the dough to cool for about 5 minutes until it's warm but not hot to the touch. Add 2 beaten eggs, one at a time, mixing thoroughly after each until smooth and glossy.

In a small bowl, combine 1/2 cup of granulated sugar with 1 tablespoon of ground cinnamon. Mix until well blended, then set aside.

In a frying pan, heat 2 inches of vegetable oil to 350°F. Once hot, transfer the churro dough to a piping bag and pipe 4-6 inch strips directly into the oil; fry for 2-3 minutes until golden brown.

Remove churro bites from oil and let drain on a paper towel-lined plate. While warm, roll each piece in the cinnamon-sugar mixture.

Serve immediately alongside the melted Nutella for dipping.
