Healthy Almond Flour Lemon Bars [Vegan, Gluten-Free]

Creamy Vegan Lemon Bars That Are Low Carb

A creamy well-baked almond flour lemon bar is a treat that I love to indulge in. It only gets better when it’s from a gluten free lemon bar recipe that’s also vegan and low carb. That sounds like a lot, but really these bars are such a simple delicious treat, you’ll have to remind yourself it’s vegan.

This recipe is actually perfect for a newly vegan family. Fresh lemons give the creamy top layer a satisfying balance of sweet and tart that kids and adults will both love. The almond flour crust is cookie like, and together, the curd and crust transform a familiar dessert into a vegan favorite. 

My vegan lemon bars are made without vegan butter and instead use natural sweeteners, gluten-free flours, and common baking ingredients to make sweet lemony goodness. It’s a great recipe to have on hand, and a delicious way to indulge on a plant-based diet.

Ingredients for Almond Flour Lemon Bars

For perfect gluten free lemon bars you’ll need an alternative flour blend to create a crust for the creamy curd to sit on. The curd itself is easy to make on the stove with a handful of simple ingredients. 

For the gluten-free almond base:

  • Almond flour
  • Tapioca flour
  • Coconut oil
  • Baking powder
  • Maple syrup

For the vegan lemon curd topping:

  • Lemons, juiced and zested
  • Canned coconut milk, full fat
  • Rice malt syrup
  • Cornflour 
  • Coconut oil
  • Vanilla extract
  • Turmeric, optional

What Substitutions Can I Use?

If you’re wondering, almond meal is the same as almond flour and you can absolutely use it here. You may also want to know that the alternative name for cornflour, is cornstarch. It can be substituted for tapioca flour if need be. 

Sometimes, rice malt syrup is also called brown rice syrup. If you’re having trouble finding it, check near the maple syrup and honey. Finally, turmeric is completely optional here. It adds the yellow color some cooks prefer in lemon flavored baked goods, but it does nothing else to the recipe. 

Together, this blend of ingredients comes together in a magical way, creating not only a vegan and gluten free dessert, but also making these almond flour lemon bars low carb! All that is just a simple bonus however, when you take your first delicious bite.

Making the Gluten-Free Almond Flour Crust

Get started by first lining an 8×8 baking dish with parchment paper and preheating your oven to 350°F. You’ll also need a small saucepan, a bowl, and a whisk. 

To make vegan lemon bars, we’ll be harnessing the healthy fat of coconut oil to make the almond flour base. Start by whisking the tapioca and almond flours together with the baking soda. Then add the coconut oil and maple syrup and mix.

When it has all come together begin pressing the dough into the bottom of your prepared pan. Use your fingers to gently even it out, then bake until the top begins to lightly brown.

Making the Low Carb Vegan Lemon Curd Filling

To make the lemon topping, start by whisking the lemon juice and corn flour together in the cold saucepan until all the lumps are gone. It’s important to do this off heat or your curd may end up loose or lumpy.

Only when smooth, whisk in the remaining curd ingredients and then place it over medium high heat. Stir continuously until the curd begins to thicken. Once its texture is thickened to the texture of a yogurt, remove it from the heat.

Pour the finished curd over the baked almond flour crust, and place the whole thing in the fridge to chill for at least 3 hours or until set and sliceable. 

When ready, slice your low carb lemon bars into 9 squares and enjoy them straight out of the fridge the rest of the week.

What is the Best Way to Store Vegan Lemon Bars?

It’s important that you keep your almond flour lemon bars in the fridge until you’re ready to eat. The fridge keeps the curd set and the bars delicious for an entire week. 

While they can’t hang out on the counter for too long, they do hold up well in the freezer. Go ahead and freeze individual squares or the whole batch, then thaw in the fridge and enjoy when you’re ready.
