Make the Dough:
In a bowl, mix together the flour, sugar, salt, baking powder, and cinnamon.
Cut in the cold butter using a fork or pastry cutter until the mixture is crumbly.
Stir in the sourdough discard and milk, mixing until a soft dough forms.
Roll & Cut:
Lightly flour a surface and roll the dough into a 1/4-inch thick rectangle.
Cut the dough into 1/2-inch wide strips, approximately 6 inches long.
Twist the Strips:
Twist each strip a few times and place it on a parchment-lined baking sheet.
Bake:
Preheat the oven to 375°F (190°C).
Bake for 15–18 minutes or until the twists are golden and crisp.
Coat in Cinnamon Sugar:
In a shallow dish, mix together sugar and cinnamon.
Brush the warm twists with melted butter and roll them in the cinnamon-sugar mixture.
Serve & Enjoy:
Serve warm for a soft, buttery texture or let cool for extra crispiness. These twists are perfect as a quick snack, with coffee, or for afternoon tea!
