Vegan Gluten-Free Lemon Bars Recipe

Introduction

If you love desserts that are bright, refreshing, and perfectly balanced between sweet and tart, these Vegan Gluten-Free Lemon Bars are a must-try. Featuring a nutty almond-oat crust and a creamy coconut lemon filling, these bars deliver vibrant citrus flavor while staying completely dairy-free and gluten-free.

Traditional lemon bars rely on eggs and butter to achieve their smooth texture and rich flavor. This recipe uses coconut milk and cornstarch instead, creating a silky lemon custard that sets beautifully once chilled. The result is a dessert that’s just as creamy and satisfying as the classic version—without any animal products.

These lemon bars are perfect for spring gatherings, brunch tables, or anytime you’re craving a bright citrus dessert that feels light yet indulgent.

Why I Love This Recipe

There are many reasons why these vegan lemon bars have become a favorite.

First, the crust is made from almond flour and oat flour, creating a delicious nutty base that’s naturally gluten-free and full of flavor.

Second, the lemon filling is incredibly creamy, thanks to rich coconut milk and fresh lemon juice. It has the perfect balance of sweet and tart.

Another reason I love this recipe is that it’s naturally sweetened with maple syrup, which adds subtle depth while keeping the dessert refined sugar-friendly.

If you enjoy wholesome homemade treats, these lemon bars pair nicely with baked favorites like Moist 1-Bowl Banana Bread – The Easy Recipe That Never Fails.
