In a large mixing bowl, combine the flour and salt.
Cut in the butter until the mixture takes on a crumbly texture.
Mix in the egg, grated cheese, and jalapeños until well incorporated.
Form the dough into a ball, wrap in plastic wrap, and chill in the refrigerator for at least one hour.
Preheat your oven to 400°F (200°C).
Roll the chilled dough into 1-inch balls and place them on a greased or parchment-lined baking sheet, leaving some space between each.
Flatten the balls slightly with the bottom of a mug or jar.
Bake for about 15 minutes, or until they start to turn a light golden color.
Let them cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
