Preheat oven to 425°F. Line a baking sheet with parchment paper and set aside.
In a bowl, mix ¼ cup sugar and 1 tsp cinnamon. Set aside.
Add water, butter, brown sugar, and salt in a medium saucepan over medium heat. Heat until butter melts and mixture comes to a boil.
Remove from heat and mix in flour with a wooden spoon. The mixture will come together and pull away from the sides of the pot. In three additions, slowly add in the beaten eggs, mixing well before the next addition.
Form balls with the dough, about 1 inch big, and place them on the parchment lined baking sheet. Alternatively, you can fill a pastry bag with the dough and pipe it onto the baking sheet.
Bake for 10-12 minutes, or until churros are golden brown. Remove from oven and roll in sugar/cinnamon mixture while still hot.
