In a medium bowl, add the flour, baking powder and salt; whisk all of the ingredients together. Using a box grater, grate the butter atop. Mix the butter throughout the flour, breaking it up into pea-sized bits. Add the cheddar and scallions and toss until it’s thoroughly distributed throughout the flour/butter mixture.

Create a well in the center of the flour mixture and pour the beer in and mix until combined. Knead the biscuit dough a few times in the bowl and then pour it out onto a clean kitchen surface. Bring the dough together into a 1-inch thick square. Using a knife, cut out 6 rectangular shaped biscuits. Transfer the biscuits to the baking sheet and transfer to the freezer to chill for 15 to 20 minutes. Preheat the oven to 400 degrees F.

Bake for 15 to 20 minutes, until medium golden brown on top. Serve with your favorite soup.
