What could be more refreshing than key lime bars on a hot day? These no-bake key lime bars offer all the bright, tangy flavor of a classic key lime dessert with a light, plant-based twist—and they require no oven. Made from wholesome ingredients like cashews, dates, almonds, and coconut, this vegan and gluten-free version is easy to prepare and ideal for summer gatherings, potlucks, or a simple family dessert.
These bars have a naturally sweet, chewy base made from almonds, shredded coconut, and pitted dates, while the filling is a creamy cashew-based lime custard made smooth with canned coconut milk, melted coconut oil, and a touch of vanilla and sweetener. The result is a bright, tangy slice that holds together well after chilling and slices cleanly for an attractive presentation. Garnish with thin lime slices, a little lime zest, edible flowers, or fresh berries to make them extra festive.
Ingredients for No-Bake Key Lime Bars
Base
- ½ cup packed pitted dates
- 1 cup almonds
- ½ cup shredded coconut
Filling
- 4 tbsp fresh lime juice
- 1 cup canned coconut milk (use mainly the solids)
- 2 tsp liquid stevia, or sweetener of choice (adjust to taste)
- 2 tsp vanilla extract
- 3 tbsp melted coconut oil
- 2 cups raw cashews, soaked for 8 hours or softened by 30 minutes in boiling water
How to Make No-Bake Key Lime Bars
1. Make the base. Add the almonds to a blender or food processor and pulse until coarsely ground. Add the packed pitted dates and shredded coconut, then pulse again until the mixture is sticky and holds together when pressed. If your dates are dry, soak them in warm water for about 20 minutes, drain, and then use; moist dates yield the best texture.
2. Press the base. Line an 8-inch square pan with parchment paper. Transfer the base mixture into the pan and press it down firmly and evenly to form a compact crust. A flat-bottomed cup or measuring cup works well to press the mixture.
3. Prepare the filling. Drain the soaked cashews and add them to a high-speed blender or food processor with the lime juice, canned coconut milk (mainly the thick solids), liquid stevia (or other sweetener), vanilla extract, and melted coconut oil. Blend until completely smooth and creamy. A high-powered blender will produce the silkiest texture; a regular food processor can work but may require more blending time and occasional scraping.
4. Assemble and chill. Pour the lime filling over the pressed base and spread it evenly. Cover and refrigerate for at least 3 hours, or until fully set. For faster results, freeze for one hour and then transfer to the refrigerator to finish setting. Once set, slice into squares.
5. Serve. Garnish slices with thin lime rounds, a little lime zest, edible flowers, or fresh berries such as raspberries or blueberries. These touches brighten the presentation and add complementary flavors.
Recipe Tips and Storage
- Freezer friendly: Store the bars in an airtight container in the freezer. Thaw in the refrigerator a few hours before serving for the best texture.
- Sweetener options: Replace liquid stevia with another liquid or powdered sweetener of your choice—maple syrup, agave, or a granulated sugar substitute all work; adjust the amount to taste.
- Nut substitutions: If you prefer, swap the almonds in the crust for pecans or walnuts for a different flavor profile.
- Texture notes: For the creamiest filling, ensure cashews are fully softened by soaking and use the thick portion of canned coconut milk where possible.
Equipment
- Blender or food processor (a high-speed blender gives the smoothest filling)
