Gluten-Free Lemon Bars (Grain-Free)
How can you NOT love lemon bars? The taste is a remarkable contrast of sour lemon sweetened with just enough sugar to get an amazing citrusy tang without making your mouth pucker. They have a velvety smooth filling not quite like any other dessert. As if that wasn’t spectacular enough, you add a thick, buttery, vanilla shortbread crust (sometimes the crust is the best part) and you've got yourself a winning dessert. It’s a perfect combination of flavors and texture that’ll delight your taste buds.You had better make two pans—maybe three.
If gluten or grains is something you (or someone you know) must avoid at all costs you can still enjoy delectable lemon bars. With Otto’s Naturals Cassava Flour it is not only possible, but easy, to enjoy not just lemon bars but all of your favorite baked goods. Just use it as a one-to-one substitute by weight for all purpose flour or reduce volume by 25% and still get the same amazing results you remember.

Grain-Free Lemon Bars Ingredients:
- 1 stick (½ cup) unsalted butter (melted)
- ¼ cup granulated sugar
- 1 tsp vanilla extract
- ¼ tsp sea salt
- ¾ cup Otto’s Naturals Cassava Flour
Otto’s Cassava Flour Lemon Filling
- 1 cup granulated sugar
- 3 tbsp Otto’s Naturals Cassava Flour
- 3 large eggs
- 1 tsp lemon zest
- ½ cup lemon juice
- Powdered sugar to dust top
Lemon Bar Directions:
- Preheat the oven to 325°F and line and grease an 8x8 baking pan.
- For the Crust mix melted butter, sugar, and vanilla in a medium bowl. Add flour and mix until combined. The dough will be thick. Press firmly into the prepared baking pan. Bake for 20-22 minutes or until the edges are light brown. Once removed from the oven, poke holes over top of the warm crust using a fork. This helps the filling stick and holds the crust in place.
- For the Filling sift the sugar and flour together in a large bowl. Add lemon juice, zest, and eggs and whisk until completely combined.
- Pour filling over the warm crust. Bake for 22-26 minutes or until the center is relatively set and no longer jiggles. Remove bars from the oven and allow to cool at room temperature.
- Once cooled, lift the parchment out of the pan. Dust with powdered sugar and cut in squares or triangles before serving. Note: if the bars are not completely cooled the powdered sugar will disappear!
- Cover and store bars in the refrigerator for up to one week.
How do you make the best lemon bars?
Use real lemons. No skimping on this. You just can’t get the same great flavor from a bottle. You will need them anyway in order to make the lemon zest called for in the recipe.
If you have one, use a glass pan. It works better than a metal pan plus you won’t have to worry about a metallic taste transferring to your yummy bars.
Lining a pan with parchment paper is always a good idea though if that's what you're using - it makes for easy cleanup and also easier to get the bars out of the pan!
How to pick a perfect lemon
Now that you have found the perfect flour, you will be wanting to find the perfectly ripe lemon. For the best lemons look for a smooth or glossy texture. If it’s too bumpy it will be under-ripe or not juicy. Another sign of ripening is a waxy sheen. Since all citrus fruit, including lemons ripen on the tree, be sure to pick one that is that bright cheery shade of yellow. It won’t get any more ripe after you bring it home.
To squeeze or not to squeeze? While squeezing fruit while you shop is generally frowned upon, when it comes to citrus, it’s a must. The juiciest lemons are not the hard ones but the ones that give a little when squeezing them. A lemon that is too hard will be either under-ripe or shriveled inside.
Softer lemons will have not only more juice but also will be easier to juice. So pick a lemon and gently press it with your thumb, if it gives a little this is the one you want to take home.
How to get more juice from a lemon
How do you get the most juice for the least amount of work?
Place the whole lemon onto a paper towel or plate. Microwave for 10 second if the lemon is at room temperature or 20 seconds if it was in the refrigerator.
Before cutting, lay the lemon down on its side on your countertop or cutting board. With the palm of your hand press down and roll with moderate pressure back and forth for 25-30 seconds. This will soften the inside membrane of the lemon and you’ll get more lemon juice.
Cut lemon in half and juice the lemon using a juicer. My favorite juicer is a hand held one. It produces almost twice the juice in half the time and super easy to use. Double score!
What’s the best way to cut lemon bars?
First and most important, let them cool completely (yes completely) and then place them in the fridge. I know they are tempting to eat right away, but try waiting. They need at least an hour in the fridge. If you have the willpower, overnight is best.
Take them out of the fridge and cut them right away. Use a knife that has been run under hot water. Make one cut, dry the knife, run under hot water, and repeat. Do this each time and your lemon bars will have that perfect just-came-from-the-bakery look.
