Ingredients You’ll Need

Nothing fancy. Nothing weird. Just a solid lineup doing its job.
For the crust:
- Almond flour – 1½ cups
Because keto crusts don’t believe in wheat. - Melted butter – ¼ cup (4 tbsp)
Salted or unsalted, I won’t judge. Butter is butter. - Granulated keto sweetener – 2 tbsp
Monk fruit or erythritol works great. - Pinch of salt – about ⅛ tsp
Yes, even in dessert. Trust me.
For the lemon cheesecake filling:
- Cream cheese (softened) – 16 oz (2 blocks)
Full fat only. This is cheesecake, not a diet salad. - Heavy whipping cream – ½ cup
For that rich, fluffy texture. - Powdered keto sweetener – ¾ cup
Powdered = smooth, not gritty. Important. - Fresh lemon juice – ¼ cup
Bottled lemon juice is… fine, but fresh is better. - Lemon zest – 1 tbsp
Tiny effort, huge payoff. - Vanilla extract – 1 tsp
Lemon’s best friend. - Pinch of salt – about ⅛ tsp
Again. Dessert needs balance, people.
Step-by-Step Instructions

1. Make the crust
Mix almond flour, melted butter, sweetener, and salt in a bowl. It should look like damp sand, not soup.
Press it firmly into a lined pan use the bottom of a glass if you want to feel professional.
Pop it in the fridge while you make the filling. No oven. Still winning.
2. Whip the cream
In a separate bowl, whip the heavy cream until stiff peaks form.
This means it holds its shape when you lift the whisk, not when it looks “kind of fluffy.”
Set it aside like it’s waiting for its big moment.
3. Mix the cheesecake base
Beat the softened cream cheese until smooth and lump-free.
Add powdered sweetener, lemon juice, lemon zest, vanilla, and salt.
Taste it. Adjust sweetness or lemon because you’re the boss here.
4. Fold it together
Gently fold the whipped cream into the cream cheese mixture.
Don’t aggressively stir this isn’t CrossFit.
You want it light, airy, and dreamy.
5. Assemble
Spread the filling evenly over the chilled crust.
Smooth the top like you care (even if you don’t).
Tap the pan lightly to get rid of air bubbles.
6. Chill. Seriously, chill.
Refrigerate for at least 4 hours, preferably overnight.
This is non-negotiable unless you enjoy lemon cheesecake soup.
Once set, slice into bars and try not to eat half the pan immediately.
Common Mistakes to Avoid
- Using cold cream cheese. You’ll get lumps. Sad, stubborn lumps.
- Skipping the powdered sweetener. Granulated sweetener = gritty cheesecake. Rookie move.
- Not chilling long enough. Patience is part of the recipe, sorry.
- Overmixing after adding whipped cream. You’ll deflate it. RIP fluffiness.
- Forgetting the salt. Sweet without salt tastes flat. Science.
Pro tip: If your bars seem too soft, they just need more chill time. Not a meltdown. Breathe.
Alternatives & Substitutions
Because flexibility is sexy.
- No almond flour? Use pecan flour or crushed keto cookies for the crust.
- Dairy-free-ish option: Coconut cream can replace heavy cream, but the flavor will change. FYI.
- Extra lemon lover? Add more zest. Lemon zest never hurt anyone.
- Want it sweeter? Increase sweetener gradually. Taste as you go—don’t freestyle blindly.
- Chocolate twist? Add a thin layer of melted keto chocolate on top once set. Dangerous but worth it.
Personally, I love these plain and lemony, but you do you.
Final Thoughts

Make them for guests. Make them for yourself. Make them at midnight because life is hard and lemon cheesecake helps.
Now go slice a bar, admire your work, and enjoy the fact that you just made something impressive with minimal effort. You’ve earned it.
