Health notes

  • High protein: A little protein powder lifts a classic butter cookie.
  • Low carb: Almond flour replaces wheat flour.
  • Sugar-free: Powdered keto sweetener keeps the texture smooth.
  • Rich but light: 70 calories per cookie makes portioning easy.

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

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.
