I burned my first batch of these lemon bars so badly the smoke alarm got involved.
Second batch? Gone in one afternoon. My neighbor knocked on my door asking what smelled so good.
That’s the thing about a good lemon bar. It doesn’t whisper. It announces itself.
These gluten free lemon bars have a soft almond flour crust, a creamy cheesecake layer, and a lemon curd top that’s sharp enough to wake you up. No wheat flour anywhere in sight, and honestly, you won’t miss it.
Let’s get into it.
What You’ll Need
Here’s everything going into this recipe. Nothing weird, nothing you can’t find at a regular grocery store.
For the crust:
- 1 ½ cups almond flour
- 3 tbsp melted butter (or coconut oil)
- 2 tbsp honey or maple syrup
- Pinch of salt
For the cheesecake layer:
- 8 oz cream cheese, softened
- ¼ cup sugar
- 1 egg
- 1 tsp vanilla extract
For the lemon layer:
- 4 large eggs
- 1 cup sugar
- ⅔ cup fresh lemon juice (about 4 to 5 lemons)
- 1 tbsp lemon zest
- ¼ cup gluten free flour blend (or cornstarch)
For the top:
- Powdered sugar, for dusting
- Fresh blueberries and lemon slices, for garnish
That’s it. Nine ingredients doing the heavy lifting.
Tools You’ll Need
- 8×8 inch baking pan
- Parchment paper
- Mixing bowls (2, medium size)
- Whisk
- Zester or microplane
- Citrus juicer (makes this so much faster)
- Fine mesh sieve for dusting powdered sugar
Pro Tips
I’ve made this recipe more times than I can count, and here’s what actually makes a difference.
1. Use real lemons, not bottled juice. The bottled stuff tastes flat. Fresh lemon juice has this brightness that bottled juice just can’t fake.
2. Room temperature cream cheese is non negotiable. Cold cream cheese means lumps, and lumps mean a cheesecake layer that looks more like cottage cheese than silk.
3. Let the crust cool before adding filling. I skipped this step once. The filling slid right off the warm crust and made a mess. Ten minutes of patience saves you a headache.
4. Don’t skip the parchment paper overhang. Leave extra hanging over the sides of the pan. It lets you lift the whole thing out later instead of digging bars out with a spatula.
5. Chill longer than you think you need to. These bars need at least 3 hours in the fridge. Overnight is even better. The lemon layer needs time to fully set.
How to Make Gluten Free Lemon Bars
Step 1: Make the Crust
Preheat your oven to 350°F. Line your 8×8 pan with parchment paper, leaving some overhang on the sides.
Mix almond flour, melted butter, honey, and salt in a bowl until it looks like wet sand.
Press it firmly into the bottom of the pan. Bake for 10 minutes, then set aside to cool.
Step 2: Make the Cheesecake Layer
While the crust cools, beat the cream cheese, sugar, egg, and vanilla together until smooth.
Spread this over the cooled crust in a thin, even layer.
Step 3: Make the Lemon Layer
Whisk the eggs, sugar, lemon juice, lemon zest, and gluten free flour together until fully combined.
Pour this mixture over the cheesecake layer.
Step 4: Bake
Bake at 350°F for 25 to 30 minutes. The center should jiggle slightly but not look liquid.
Let it cool at room temperature for 30 minutes, then move it to the fridge.
Step 5: Chill and Serve
Chill for at least 3 hours, though overnight works best.
Lift the bars out using the parchment overhang. Dust with powdered sugar and top with blueberries and lemon slices right before serving.
Substitutions and Variations
- Dairy free? Swap cream cheese for a dairy free cream cheese alternative and use coconut oil instead of butter.
- Lower sugar? Reduce sugar in the lemon layer to ¾ cup. It’ll be more tart, less sweet.
- No almond flour? A gluten free graham cracker crust works too, though it won’t be as low carb.
- Want it extra tangy? Add an extra tablespoon of lemon zest to the filling.
- Berry swap: Raspberries work just as well as blueberries for the topping.
Make Ahead Tips
These bars are actually better the next day. The flavors settle and the texture firms up.
You can make them up to 3 days ahead and store covered in the fridge until you’re ready to serve.
The crust can also be made a day in advance and kept covered at room temperature.

Leftovers and Storage
Store leftover bars in an airtight container in the fridge for up to 5 days.
You can also freeze them. Wrap each bar individually in plastic wrap, then place in a freezer bag for up to 2 months.
Thaw in the fridge overnight before serving. Do not thaw at room temperature, or the cheesecake layer gets watery.
FAQ
Can I double this recipe? Yes, just use a 9×13 pan and add about 10 extra minutes to the bake time.
Why is my lemon layer runny? It likely needed more time in the oven, or it hasn’t chilled long enough. Give it the full 3 hours in the fridge before slicing.
Can I use bottled lemon juice in a pinch? You can, but the flavor won’t be as bright. Fresh is worth the extra 5 minutes.
Do these need to stay refrigerated? Yes, because of the cream cheese layer. Keep them chilled until right before serving.
Can I make this recipe vegan? It gets tricky with the eggs in the lemon layer, but a flax egg substitute has worked for some readers. Texture will be softer.
Wrapping Up
There’s a reason lemon desserts show up at every spring gathering and summer potluck.
They’re bright, they’re a little unexpected, and they make people ask for the recipe before they’ve even finished the first bite.
Make these once and you’ll understand why my neighbor keeps finding excuses to stop by.
