Preheat oven to 450°F.
In a medium bowl, combine flour, baking powder, and salt.
Stir in oil and beer until a stiff dough forms.
Turn out onto a floured work surface and knead lightly 4 or 5 times.
Using a floured rolling pin, roll dough to 3/4” thickness.
Using a pizza cutter, cut dough into 12 squares.
Place on a parchment-lined baking sheet and bake until golden brown, 10 to 12 minutes. Remove from oven and serve warm.
