Key element — silky lemon filling
Full-fat cream cheese for body, thick Greek yogurt for protein and tang. Always use powdered sweetener (no grit) and real lemon zest. Chill at least 2 hours — overnight for the cleanest slices.
Ingredients
- 1½ cups almond flour
- 3 Tbsp powdered erythritol or monk fruit
- ¼ tsp salt
- 5 Tbsp melted butter (or coconut oil)
- ½ tsp vanilla extract
- 12 oz cream cheese, softened
- 1 cup plain full-fat Greek yogurt (thick/strained)
- ⅓ cup powdered erythritol or monk fruit
- Zest of 2 lemons + 3–4 Tbsp fresh lemon juice
- 1 tsp pure vanilla extract
- 1 scoop (25–30g) unflavored or vanilla protein (optional, for ~9g protein)
- Pinch of salt
- ¾ cup heavy cream + 1–2 Tbsp powdered sweetener
- Extra lemon zest for garnish
- Optional: sugar-free white chocolate or berries
- Dairy-free: Vegan cream cheese + coconut yogurt; coconut cream topping; plant protein.
- Nut-free crust: Sunflower seed flour or crushed sugar-free cookies + butter.
- No protein powder: Skip it — still great (~6–7g protein).
- Extra lemon: Add ½ tsp lemon extract with the juice.
Instructions
| 1 | Make the crust. Mix almond flour, powdered sweetener, and salt. Stir in melted butter and vanilla. Press into a parchment-lined 8×8-inch dish. Chill 10 minutes (or bake 8–10 min at 350°F for a toastier crust, then cool). |
| 2 | Beat the filling. Beat softened cream cheese until smooth. Add sweetener, zest, juice, vanilla, salt, and protein powder if using. Mix in Greek yogurt on low until just combined. |
| 3 | Assemble. Spread filling over crust. Smooth the top. Cover and refrigerate at least 2 hours (overnight for cleanest cuts). |
| 4 | Whip the topping. Whip cold cream with powdered sweetener to soft-stiff peaks. Spread or pipe over the set layer. Finish with fresh lemon zest. |
| 5 | Slice and serve. Lift out with parchment. Cut into 12 bars with a hot, clean knife. Serve cold. Fridge up to 5 days or freeze up to 2 months. |
Pro tips
- Room-temp cream cheese only — cold cream cheese creates lumps.
- Powdered sweetener in no-bake fillings (never granular).
- Strain watery yogurt 20–30 minutes for a denser set.
- Zest lemons before juicing for maximum aroma.
- Hot knife + wipe between cuts = bakery-clean slices.
