Once you see how easy it is to learn how to make homemade biscuits, you will make these all the time. These biscuits are light and fluffy and easy to make.
Heat oven to 450 degrees. Line a baking sheet with parchment paper.
In the bowl of a food processor, combine 2¾ cups all-purpose flour, ¼ cup cornstarch, 4½ teaspoons baking powder, and ½ teaspoon salt. Pulse a few times to combine.
Cut ½ cup cold salted butter into 4 to 5 pieces. Add the butter to the food processor and pulse for about 10 seconds, until the mixture is crumbly and the butter is distributed in small pieces throughout the flour mixture.
Add ½ cup whole-fat plain Greek yogurt, ¼ cup heavy whipping cream, ? cup whole milk, and 1 large egg to the food processor.
Remove from bowl onto rolling surface that is lightly covered with corn starch. Knead the dough a few times turning it over onto itself and turning about 6 - 10 times.
Use rolling pin to roll out to 9 X 12 rectangle. It will be about ¾ inch thick.
Cut into 15 - 18 rectangles and place on parchment lined baking sheet.
Bake on middle rack at 450 degrees for 8 - 12 minutes until biscuits are lightly browned.
Notes
TIPS in the food processor: If the dough is too wet and doesn’t stay lumped together add 1 tablespoon of all-purpose flour and pulse. Repeat until dough is solid enough to handle. If dough is too dry, add 1 teaspoon of water and pulse. Repeat adding tiny amounts of water until all the dough sticks together in a ball.
