In a large bowl, mix together the all-purpose flour, salt, black pepper, and garlic powder.

Add the cold, cubed unsalted butter to the flour mixture and blend until it resembles coarse crumbs.

Gently stir in the shredded sharp cheddar and finely diced jalapeños until evenly distributed.

Gather the mixture into a ball, then wrap it in plastic wrap and refrigerate for 30 minutes.

Remove the dough from the fridge and slice it into bite-sized pieces. Arrange them on a baking sheet lined with parchment paper.

Preheat your oven to 350°F (175°C) and bake the pieces for 18–22 minutes.

Garnish with a sprinkle of sea salt right after baking for an extra flavor pop.
