Method
Make the butterbeer cookie dough
- Beat the softened butter and brown sugar until smooth, then stream in the melted butterscotch chips. Mix in the egg, vanilla, and cream soda until combined, scraping the sides as needed.
- Whisk together the flour, baking soda, baking powder, cinnamon, and salt, then fold the dry mixture into the wet ingredients just until no dry streaks remain. Scoop 2-tablespoon rounds and place them on a sheet pan with space between.
Bake and cool
- Bake at 375°F for 10–12 minutes, until the edges look set and the centers are still soft. Let the cookies cool completely on the pan before frosting.
Make frosting and decorate
- Beat the softened unsalted butter with the butterscotch sauce until smooth, then mix in powdered sugar in batches. Add vanilla and enough cream soda (2–3 tbsp total) to make the frosting fluffy and pipeable.
- Pipe or spread frosting onto each cooled cookie, then decorate with gold sugar sprinkles. Let the frosting set for a few minutes before serving.
Notes
Pro tip: cool the baked cookies fully before frosting so the cream-soda butterbeer frosting stays thick and doesn’t melt. Store cookies in an airtight container for 3 days at room temperature, or refrigerate up to 5 days. Freeze frosted cookies up to 1 month; thaw in the fridge overnight. If you want a dairy-light option, use plant-butter in both the cookies and frosting for a similar texture.
