Ingredients You'll Need
Main Ingredients
**For the Crust:**
**All-purpose flour (or gluten-free blend)**
This forms the base of your shortbread-style crust. All-purpose works beautifully, but a good gluten-free flour blend can be substituted for a gluten-free version.
**Coconut oil or vegan butter**
This creates the rich, buttery flavor and crumbly texture. Coconut oil adds a subtle tropical note, while vegan butter tastes more traditional.
**Powdered sugar**
Sweetens the crust while keeping it tender. Powdered sugar dissolves more easily than granulated, creating a smoother texture.
**Vanilla extract**
Just a touch enhances the overall flavor and balances the lemon's tartness.
**Salt**
A small pinch brings out all the other flavors and prevents the crust from tasting flat.
**For the Lemon Filling:**
**Fresh lemon juice**
The star of the show. Fresh is essential here—bottled lemon juice simply won't deliver the same bright, vibrant flavor.
**Lemon zest**
Adds intense lemon flavor and beautiful flecks of color throughout the filling.
**Full-fat coconut milk or coconut cream**
Creates the creamy, luxurious texture in the filling. Full-fat is important for richness.
**Granulated sugar**
Sweetens and balances the tartness of the lemons. You can adjust to taste.
**Cornstarch or arrowroot powder**
Acts as the thickening agent, replacing the role eggs play in traditional lemon bars.
**Turmeric (optional)**
Just a tiny pinch gives the filling a more golden, traditional lemon bar color without affecting the flavor.
Optional Add-Ins
- Extra lemon zest for garnish
- Fresh berries for serving
- Coconut whipped cream for topping
- A dusting of powdered sugar for presentation
Step-by-Step Instructions
Step 1: Prepare Your Pan and Preheat
Line an 8x8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal later. Preheat your oven to 350°F (175°C).
**Tip:** Don't skip the parchment paper—it makes removing and cutting the bars so much easier and prevents sticking.
Step 2: Make the Crust
In a medium bowl, combine 1 and 1/2 cups all-purpose flour, 1/3 cup powdered sugar, and 1/4 teaspoon salt. Add 1/2 cup melted coconut oil (or softened vegan butter) and 1/2 teaspoon vanilla extract. Mix until the mixture resembles wet sand and holds together when pressed.
Press the mixture firmly and evenly into the bottom of your prepared pan, making sure to get into the corners.
Step 3: Bake the Crust
Bake the crust for 18-20 minutes, until the edges are lightly golden. You want it fully cooked but not deeply browned. Remove from the oven and let it cool slightly while you prepare the filling.
**Tip:** A properly baked crust is essential—it should feel firm to the touch and not look wet or doughy in the center.
Step 4: Prepare the Lemon Filling
While the crust bakes, whisk together 2/3 cup fresh lemon juice (about 3-4 lemons), 1 tablespoon lemon zest, 3/4 cup full-fat coconut milk, 3/4 cup granulated sugar, and 1/3 cup cornstarch in a medium saucepan. Add a tiny pinch of turmeric if you want a more golden color.
Place the saucepan over medium heat and whisk constantly. The mixture will start thin, but after 5-7 minutes, it will suddenly thicken into a smooth, pudding-like consistency. Keep whisking to prevent lumps.
Step 5: Combine and Bake
Pour the thickened lemon filling over the warm crust, spreading it evenly to the edges. Return the pan to the oven and bake for another 10-12 minutes. The filling should look set around the edges but still have a slight jiggle in the center—it will firm up as it cools.
Step 6: Cool Completely
Remove the pan from the oven and let it cool at room temperature for about 30 minutes, then transfer to the refrigerator. Chill for at least 2-3 hours, or until the filling is completely set and firm to the touch. This patience is key to clean, beautiful cuts.
Step 7: Slice and Serve
Using the parchment paper overhang, lift the entire slab out of the pan. Place it on a cutting board and use a sharp knife to cut into squares. For the cleanest cuts, wipe your knife clean between each slice.
Dust generously with powdered sugar just before serving for that classic lemon bar look.
Serving Ideas
You can enjoy Vegan Lemon Bars on their own, or serve them with:
- A dollop of coconut whipped cream for extra indulgence
- Fresh raspberries or blueberries on the side for color and complementary flavor
- A sprig of fresh mint for an elegant garnish
- A light dusting of additional lemon zest for visual appeal
For a more polished look, serve on a white plate or cake stand to make the golden color pop.
Tips for the Best Results
- Use fresh lemon juice only—bottled juice lacks the bright, vibrant flavor that makes these bars special
- Don't skip chilling the bars completely—this is essential for clean slicing and proper texture
- Press the crust firmly into the pan to prevent it from being crumbly when you cut the bars
- Whisk the filling constantly while heating to avoid lumps in your smooth, creamy topping
- Let the bars come to room temperature for 10-15 minutes before serving for the best flavor and texture
Storage Instructions
Store leftover Vegan Lemon Bars in an airtight container in the refrigerator for up to 5 days. The bars actually taste better after the first day as the flavors meld together.
To prevent the topping from becoming soggy, place a piece of parchment paper between layers if stacking. Keep the powdered sugar garnish off until just before serving, as it will dissolve in the fridge.
This recipe is not recommended for freezing due to the texture changes that occur in the coconut-based filling when thawed.
Are Vegan Lemon Bars Healthy?
While these are still a dessert meant to be enjoyed in moderation, Vegan Lemon Bars are made with plant-based, simple ingredients that many people find easier to digest than traditional versions.
They contain:
- No cholesterol (since they're completely plant-based)

Compared to traditional lemon bars, this recipe eliminates eggs and dairy, making it lighter on the digestive system and suitable for those with common food sensitivities. The use of whole ingredients without artificial flavors or colors is an added benefit.
That said, they still contain sugar and should be enjoyed as an occasional treat rather than an everyday food. The good news is that because they're so rich and satisfying, a small square is usually enough to satisfy your sweet tooth.
