A few of our staple low carb ingredients come together to make these decadent and velvety low carb lemon bars –
Almond flour – this gluten free four is a low carb staple. Almonds are blanched and finely ground to make flour in all kinds of coarseness. You’ll want a fine grind of flour for these low carb lemon bars — my favorites are Bob’s Red Mill or Trader Joe’s brand.
Xantham gum – This food additive helps bind and thicken foods, and is especially helpful in gluten free baking.
Erythritol – My favorite alternative sweetener, this plant-based sugar dupe is calorie free, carb free, and has no effect on blood sugar.
Lemon zest – The bright peel of citrus foods, called the flavedo, adds a hit of flavor and aroma when cooking and baking. Use a microplane or the fine edge of a box grater to scrape off the zest only until you get to the bitter white pith.
Butter – Keeping the butter COLD is what gives this crust that ultra buttery, crumbly texture we all crave from shortbreads and pie crusts — Which is why we take a few extra steps to freeze, grate and freeze again.
Trust me, the extra steps make a big difference in the texture!
Powdered Erythritol – Don’t feel like buying both low carb sweeteners? Toss your granular erythritol in a food processor until it’s in powdered form. Allow the dust to settle before opening the lid!
Tools To Make
A few simple tools make this cookie recipe easy breezy!
- Box grater – This classic tool is quite underutilized now that we can buy our cheese pre-shredded at the store! But, there are still many things we need it for, like getting this butter just the right size to give us a perfectly crumbly shortbread crust.
- 9×13 dish – I use a rectangular pan for making these low carb lemon bars, but you can use a 9×9 pan if that’s what you have. It’ll give you thicker bars, so adjust the nutrition.
- Parchment paper – this slippery paper makes it super easy to lift the bars out of the pan and makes clean up a breeze! I cut my parchment just a tad longer than the tray so I can lift the whole lemony cookie brick out at once.
Lemon bars have a tendency to dry out, so it’s important to keep these healthy snacks in an airtight container in the fridge. Keep them in a single layer, so they don’t stick together.
Can You Freeze Them?
Yes, and it’s a great way to keep them fresh if these low carb lemon bars are just snacks for you! A word of warning – the custard is delicate so you need to protect them.
After you cut the bars, wrap each bar well in plastic wrap, then store them all in a freezer bag. Take them out and let them thaw in the fridge overnight when you’re ready for some more!
Almost everyone puts their own spin on things like cookies – read on to see what you can customize!
- Use a different kind of crust. I modified my almond flour shortbread cookies recipe to make the crust for these bars, but you could also use my low carb graham crackers as a crust.
- Add fruit. A great way to add some extra low carb fruits to these low carb lemon bars would be to sprinkle the top with fresh raspberries or blueberries
- Want to add a little crunch? Consider mixing up chopped coconut, walnuts with erythritol for a delicious “crumb” topping, similar to my low carb apple crisp or low carb blueberry muffins!
