Begin by grating your cheese of choice and ensure that your butter, milk, and eggs are at room temperature.

In a medium saucepan, combine 1 cup of milk, 1/2 cup of butter, and a pinch of salt over medium heat until the butter melts and the mixture simmers. Add 1 cup of all-purpose flour and stir until the dough forms a cohesive ball.

Remove from heat and let the dough cool slightly, then add 3 room temperature eggs one at a time, mixing well after each addition.

Fold in your grated cheese into the dough, ensuring it is well incorporated.

Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper. Scoop tablespoon portions of the dough onto the sheet, leaving space in between. Bake for 20–25 minutes until puffed up and golden brown.

Let the cheese puffs cool on the parchment for about 5 minutes before transferring to a wire rack.
