Health notes

High protein: Cream cheese, Greek yogurt or cottage cheese, and protein powder deliver a solid boost.
Low carb: Almond flour crust and sugar-free sweetener keep net carbs very low.
Sugar-free: No added sugar — only sugar-free alternatives.
Fresh & light: Lemon zest and juice keep the flavor bright without extra carbs.

Key element — chill until fully set

These bars need time in the refrigerator so the filling firms up. Cutting too soon will smear the layers.

Ingredients

Crust

1½ cups almond flour
3 Tbsp melted butter
2 Tbsp powdered sugar-free sweetener
Pinch of salt

Lemon filling

8 oz (225g) cream cheese, softened
1 cup full-fat Greek yogurt or blended cottage cheese
1 scoop vanilla or unflavored protein powder
⅓ cup powdered sugar-free sweetener (to taste)
Zest of 1 lemon
3–4 Tbsp fresh lemon juice
1 tsp vanilla extract

Topping

¾ cup sugar-free whipped cream or extra Greek yogurt
Extra lemon zest for garnish

Swaps

Higher protein: Add an extra ½ scoop protein powder and a splash of cream if the filling thickens too much.
Dairy-free: Use dairy-free cream cheese and yogurt, plus plant-based protein.
Lime version: Swap lemon zest and juice for lime.
No crust: Pour the filling into small jars for crustless cups.

Instructions

Make the crust. Mix almond flour, melted butter, sweetener, and salt until it looks like damp sand. Press firmly into the bottom of an 8×8-inch dish. Chill while you make the filling.

Blend the filling. Beat the cream cheese until smooth. Add Greek yogurt (or blended cottage cheese), protein powder, sweetener, lemon zest, lemon juice, and vanilla. Mix until creamy and completely smooth.

Layer. Spread the lemon filling evenly over the crust. Smooth the top, then add a layer of sugar-free whipped cream or extra yogurt.

Chill and slice. Cover and refrigerate at least 2–4 hours (overnight is even better). Garnish with lemon zest, then cut into 9 bars.

Pro tips

Use fully softened cream cheese so the filling stays silky.
Press the crust firmly so it holds together when sliced.
Chill long enough — the bars slice much cleaner after a few hours.
Add topping just before serving if you want the layers extra neat.
Wipe the knife between cuts for clean squares.
