Here's the recipe:
3 cups all-purpose flour
1 Tbsp. baking powder
1 stick chilled unsalted butter, cut into small cubes
1 1/2 cups grated cheddar cheese
4 green onions, thinly sliced
10 slices bacon, cooked and chopped into 1-inch pieces
3/4 to 1 1/2 cups buttermilk*
1 large egg
2 tsp. water
*I used lemon juice mixed with 2%milk instead of buttermilk
Cook the bacon. When it cools tear it into one inch pieces.
Mix the flour and baking powder and cut in the butter until the chunks aren't any bigger than peas.
Bake on parchment paper or a silicone mat for 15-22 minutes. Mine took 15 minutes. They should be lightly brown on top and not sticky in the middle. I tested mine with a toothpick.
