Key element — use a star tip and slightly soft dough
The dough should be soft enough to pipe but not greasy. If it is too stiff, add 1 teaspoon cream. If it is too loose, chill 10 minutes.
Ingredients
Cookies (about 20)
- ½ cup (113g) unsalted butter, softened
- 2 oz (56g) cream cheese, softened
- ⅓ cup powdered sugar-free sweetener
- 1 large egg yolk
- 1 tsp vanilla extract
- 1¼ cups fine almond flour
- 3 Tbsp vanilla or unflavored protein powder
- ¼ tsp baking powder
- Pinch of salt
Swaps
- Higher protein: Add 1 extra Tbsp protein powder and 1 tsp cream if needed.
- No piping bag: Roll into balls and flatten with a fork.
- Lemon: Add 1 tsp lemon zest.
- No protein powder: Use 2 extra Tbsp almond flour.
Instructions
| 1 | Preheat. Heat the oven to 350°F (175°C). Line two baking sheets with parchment. Soften the butter and cream cheese so they beat smoothly. |
| 2 | Make the dough. Beat butter, cream cheese, and powdered sweetener until light. Mix in the egg yolk and vanilla. Stir in almond flour, protein powder, baking powder, and salt until a soft pipeable dough forms. |
| 3 | Pipe. Spoon the dough into a piping bag fitted with a large star tip. Pipe small swirls onto the parchment, leaving space between cookies. If you don’t have a bag, roll 1-inch balls and flatten. |
| 4 | Bake and cool. Bake 11–14 minutes until the edges are golden. Cool on the pan 10 minutes before moving. They crisp as they cool. |
Pro tips
- Powdered sweetener is essential for a smooth swirl.
- Fine almond flour pipes better than coarse meal.
- Don’t overbake — they should stay pale gold, not brown all over.
- If the dough is too stiff to pipe, warm it in your hands or add a teaspoon of cream.
- Store in an airtight tin so they stay crisp.
