Being vegan can involve some sacrifice, but not where dessert is involved. If you want to have a special treat for the weekend, try these vegan lemon bars.

At first, I wasn’t sure if I could make lemon squares vegan. I mean, lemon curd is almost pure eggs! But soon I realized how quick, easy, and delicious egg-free lemon bars can be!

Key Ingredients

Here are the ingredients you’ll need for this recipe:

  • Flour — All-purpose flour works great, or you can use whole wheat pastry flour, or gluten-free flour.
  • Vegan butter — I use Earth Balance buttery sticks, Miyoko’s, or homemade vegan butter.
  • Lemon — We’ll use both the zest and the juice from a lemon.

What Lemons are Best for Lemon Bars?

Look for thin-skinned lemons that do not have green spots. You may think bigger lemons would yield more juice and flavor, but this is not always the case because larger lemons have thicker skins. Each lemon should yield about 1/4 cup or more of juice. To get the most juice possible out of your lemons, you can zap them in the microwave for about 10 to 15 seconds, then roll them firmly on the counter.

For the best lemon bars, you want a perfect ratio of crust to filling. I love these tips from Cooks Illustrated on the science of lemon bars!

Option #1: Vegan Lemon Custard

I’m providing two options for the lemon curd: The first option is a tofu lemon curd. This is what the tofu lemon bars look like.

As you can see, the simple vegan curd creates lemon bars that are much more translucent. Both bars taste amazing, but the simple vegan curd bars have a more traditional look.

  1. To prepare the tofu lemon curd, combine silken tofu, lemon zest, lemon juice, sugar, cornstarch, nutritional yeast flakes, and turmeric in a food processor. (I didn’t even bother cleaning out the food processor from step one).
  2. Pulse this until smooth.
  3. Spoon it over the unbaked crust.

I know it sounds odd adding nutritional yeast flakes and turmeric to lemon curd, but it’s only a little bit and it gives it a sunny yellow color.

Quick Fix Tip

If your sauce develops lumps, finish cooking it in the saucepan and then remove it from heat. Add the remaining ingredients and transfer it to a food processor or blender and pulse in short bursts until the lumps are gone.

Option #2: Simple Vegan Lemon Curd

I like the look of the traditional lemon bar with its more translucent lemon curd. Besides, sometimes you need vegan lemon bars without tofu if you’re serving people with soy allergies.

  1. Combine the lemon juice, sugar, milk, and cornstarch in a saucepan.
  2. Cook over medium heat, stirring constantly to dissolve the sugar.
  3. Bring it to a low boil, then reduce heat to simmer and cook 2–3 minutes, stirring constantly.
  4. Once the mixture thickens, remove from heat, add the lemon extract, coconut oil, and turmeric. Stir to combine.
  5. Pour this curd over the prepared crust. 

Why This Recipe is a Winner

  • Adding vegan butter to the shortbread crust produces a rich and buttery crust
  • Using fresh lemons makes the curd taste zesty and fresh
  • Two ways to make the lemon curd gives you options for a delicious and easy dessert recipe, regardless of the ingredients you have on hand!

Storage Tips

Cover and store bars in the fridge. They will keep up to 5 days. They can be cut into individual slices and frozen for up to 2 months.

What are Vegan Lemon Bars?

Lemon bars are sort of like a lemon tart, except baked in a square pan. The nice thing is you can cut the slices into squares which is much more convenient for packing in lunches, etc.

These vegan lemon bars are a sweet treat that is easy to make and a real crowd favorite.

Marly’s Tips

  • For a change of pace, try using a vegan graham cracker crust in place of the shortbread crust
  • Make gluten-free vegan lemon bars by using gluten-free baking flour
  • You can make the crust with coconut oil instead of butter
  • Line your pan with foil, then spray it with vegetable spray to help remove the bars from the pan after they’ve cooled
  • Tamp down the crust before adding the curd to prevent the crust from rising to the top while baking
  • If you want to prevent the bars from cracking, place a shallow pan below it in the oven and fill it with water. The steam from the water adds moisture to the oven
  • You can find silken tofu in the produce section of most grocery stores. If you can’t find silken tofu, use medium-firm tofu instead

Ingredients

Vegan Shortbread Crust

Tofu Lemon Custard (Option #1)

  • 12 oz package silken tofu
  • zest of 1 lemon
  • juice of 1 lemon
  • ½ cup granulated sugar
  • 1 tablespoon cornstarch
  • 1 teaspoon nutritional yeast flakes for color
  • pinch ground turmeric (for color)

Simple Vegan Lemon Curd (Option #2)

  • ¾ cup lemon juice
  • 1 cup granulated sugar
  • 1 ½ cups plant-based milk
  • 5 tablespoons cornstarch
  • 1 teaspoon lemon extract
  • 1 teaspoon coconut oil
  • teaspoon ground turmeric

For Serving

Instructions

  • Preheat oven to 350°F/180°C. Line a 9×9-inch square pan with foil. Give the foil a light coating of vegetable spray.
  • Combine flour, butter, and powdered sugar in a food processor and pulse for several seconds, until combined, but still crumbly. Press into the bottom of the prepared pan. Top with either the Tofu Lemon Curd OR the Simple Lemon Curd.

For the Tofu Lemon Curd (Option #1)

  • If you're making your lemon bars with the tofu lemon curd: In the same food processor bowl (no need to wash it out), add the tofu, lemon zest, lemon juice, sugar, cornstarch, nutritional yeast, and turmeric. Pulse until completely smooth. Pour the lemon filling over the crust and evenly distribute across the pan.
  • Bake for 25 to 30 minutes, until the sides are golden brown and the filling is firm (if it's still overly jiggly, you should cook it a few more minutes).
  • Remove from the oven and allow to cool. After it's cooled, transfer to the fridge and chill for 1 to 2 hours. Once chilled, grab both sides of the aluminum foil and remove it from the pan.

For the Simple Lemon Curd (Option #2)

  • If you're using the simple lemon curd, in a saucepan combine the lemon juice, sugar, milk, and cornstarch. Stir to combine the cornstarch. Cook over medium heat while stirring constantly to dissolve the sugar and to prevent lumps as the mixture thickens. Bring it to a low boil, then reduce heat to simmer and cook for 2 to 3 minutes, stirring constantly. The mixture should get fairly thick. If you get lumps, simply pulse the curd in a food processor or use an immersion blender.
  • Once the mixture thickens, remove from heat, add the lemon extract, coconut oil, and turmeric. Stir to combine. Spoon out the lemon curd over the prepared crust.
  • Bake for 30 minutes, until the sides are golden brown and the filling is slightly firm. It may be a little jiggly.
  • Remove from the oven and allow to cool. After it's cooled, transfer to the fridge and chill for 2 to 3 hours. Once chilled, grab both sides of the aluminum foil and remove the bars from the pan.

To Serve:

  • Sprinkle the tops of the bars with powdered sugar. Slice into bars and serve.
  • Store lemon bars in the fridge. They will keep up to 5 days.

Notes

Be sure to tamp the crust down in the pan. This can help prevent the crust from rising to the top while baking.

Tofu

Option #1 calls for “silken” tofu. You can find that in the produce sections of a lot of U.S. grocery stores and definitely at health food stores. It may or may not be refrigerated and most typically I find it in a small “box” type container rather than a plastic tub. If you can’t find silken tofu, then buy a soft or medium regular tofu. 
The nutritional estimates are provided for the tofu curd.
For Simple Curd (option #2), be sure to allow the curd to thicken in the saucepan before proceeding. Also, use the kind of coconut oil that is solid at room temperature.
You can sub coconut oil for the vegan butter in the crust.

    hi! do you like option 1 or 2 more? can you taste the tofu in option one?

    • Avatar thumbnail image for MarlyMarly

      I prefer option #2 because I like the translucent look of the lemon curd made with cornstarch. I did not notice a tofu taste with option #2, so it’s great, especially if you have some silken tofu on hand. Hope that’s helpful Rylyn!

    You’ve mentioned how you use silken tofu for dips, creamy soup, etc..Does the tofu melt??
    Reason I’m asking, I’m thinking queso..

    • Avatar thumbnail image for MarlyMarly

      Hi Amanda. I like the way you think! You can make something like that using silken tofu. Or you can use vegan cream cheese that is made from tofu as well. Here’s a link to my vegan queso recipe. Hope this is helpful!

    Hi Marly,
    Hope you are safe and staying at home. Your recipe is amazing and delicious too. Thank you so much for sharing this recipe. My mom is very picky in desserts but when I made this (curd version) she couldn’t help but to share with other people that my daughter made this
    Since I am trying my hand in kitchen in this quarantine mode, this recipe was an ultimate saviour.

      Hi Puja! Thanks so much for your feedback. I’m honored to get a review from your mom too! Please give her a hug for me (at least a virtual one). We are in the same boat – staying home – and there is no flour to be found anywhere! Well, I did find some gluten-free flour and it works too. So glad we could connect. Stay safe!

    Hey, can I use coconut oil instead of vegan butter for the crust?

    • Avatar thumbnail image for MarlyMarly

      Hi Lexie. Great question. Yes, absolutely you can use coconut oil. I’ll add this to the notes.

    I love this recipe. It takes a party appetizer to a whole new level and so darn easy!

    The coconut oil I used was indeed solid. I thought the curd thickened up in the pan but maybe it wasn’t enough? What consistency should I be looking for? And when I say “crust” on top I don’t mean the shortbread crust that makes up the bottom of the lemon bar. I meant that the curd was slightly solid on top but fully liquid underneath.

    I made these today using option #2 the simple lemon curd and not sure where I went wrong but they have not firmed up at all. I even left them in the oven for way longer. They are in the fridge now but they are basically soup with a slight crust on top. Any suggestions or ideas where I might have goofed?

    • Avatar thumbnail image for MarlyMarly

      Hi Jay! Did the curd get thick in the saucepan? Most of the thickening occurs in the saucepan for this recipe. Also, the coconut oil should be the kind that is solid at room temperature. To prevent the crust from ending up on top, be sure to tamp down the crust in the bottom of the pan. I’ll add a note to clarify this in the instructions.

    You left the lemon zest out of the recipe for Option 2? Did you write lemon extract by mistake, or do you need both zest and extract?

    • Avatar thumbnail image for MarlyMarly

      Hi Susan! Actually, I was trying to keep Option #2 for the vegan lemon curd super simple so I used lemon extract and it worked amazing! However, you can add a teaspoon of lemon zest too if you’d like. Hope you love these vegan lemon bars!
