Health notes

Higher protein for shortbread: Vanilla protein powder plus almond flour.
Low carb: No wheat and no sugar.
Sugar-free: Powdered keto sweetener keeps the crumb pale.
Buttery: Real butter is what makes the dough lift like the photo.

Key element — keep the dough cool

Soft butter spreads too much. If the dough feels sticky, chill 10 minutes before you cut the rounds.

Ingredients

Cookies (makes 12)

1½ cups almond flour
1 scoop vanilla protein powder
⅓ cup powdered sugar-free sweetener
¼ tsp salt
½ cup butter, softened but still cool
1 large egg yolk
2 tsp vanilla extract
½ tsp almond extract (optional)

Swaps

Higher protein: Use an extra half scoop of protein powder and 1 extra Tbsp almond flour if the dough is sticky.
Dairy-free: Use coconut oil that is firm, not melted.
Lemon: Swap 1 tsp vanilla for lemon zest.
No protein powder: Add 3 extra Tbsp almond flour (protein drops).

Instructions

Heat the oven. Heat to 325°F (165°C). Line a baking sheet with parchment.

Make the dough. Whisk almond flour, protein powder, sweetener, and salt. Beat in butter, egg yolk, and vanilla until a thick dough forms that pulls from the bowl.

Shape. Roll to about ⅓-inch thick. Cut 12 rounds with a 2-inch cutter. Reroll scraps. Chill 10 minutes if the dough is soft.

Bake. Bake 12–15 minutes until the edges are just golden and the tops stay pale. Cool on the sheet 10 minutes before moving.

Pro tips

Powdered sweetener dissolves better than granulated.
Don’t bake until brown — shortbread should stay pale.
A fork press on top is optional if you want a classic look.
Cool fully before storing so they stay crisp.
If they spread, the butter was too warm.
