Ingredients
Method
- Cream the butter and 1 1/2 cups sugar until light and fluffy, about 3 minutes.
- Beat in the egg, vanilla, and sour cream until smooth.
- Gradually mix in the flour, baking powder, and salt until just combined.
- Scoop dough into 1.5 tbsp balls, roll in extra sugar, and place on parchment-lined sheets.
- Bake at 350°F for 10 to 12 minutes until edges are set; cool on the sheet 5 minutes, then transfer to a wire rack.
Notes
The cookies will look slightly underbaked when you pull them out, but they set up perfectly as they cool. Store them with a slice of bread to keep the texture extra soft for days.
