Start by preheating your oven to 425°F (220°C). In a large bowl, mix together the flour, sugar, baking powder, cinnamon, and salt. Then, cut in the cold butter until the mixture resembles coarse crumbs.
Gently fold in the blueberries, being careful not to crush them. Pour in the milk and stir until just combined, ensuring to mix lightly to keep the biscuits fluffy.
Scoop large spoonfuls of dough onto a lined baking sheet, spacing them a couple of inches apart. These biscuits are meant to be hearty and tall, so don’t worry about making them perfectly round!
Bake in your preheated oven for about 25 minutes, or until they are golden brown on top. Let them cool slightly before serving for the best experience.
Enjoy your delicious blueberry cinnamon cathead biscuits warm, perhaps with a drizzle of honey or your favorite jam.
Notes
These biscuits are best enjoyed fresh from the oven, but you can store leftovers in an airtight container for a couple of days.
