I started making these No-Bake Vegan Chocolate Hazelnut Bars on busy weekends when I wanted something homemade without turning on the oven.
The rich chocolate flavor and smooth hazelnut filling make them feel like a special dessert, but they are simple enough to prepare with just a few pantry ingredients.
These bars have become one of the easiest treats to keep in the refrigerator because they hold up well and taste even better after chilling.
The soft texture, deep cocoa flavor, and nutty hazelnut layer make them popular for after-school snacks, quick desserts, and little sweet bites during busy afternoons at home.
Why You’ll Love This Recipe
These chocolate hazelnut bars are rich, creamy, and satisfying while still being surprisingly simple to make. Since they are completely no-bake, they work especially well during warmer months or on days when you want a homemade dessert without extra kitchen cleanup.
I also love how flexible the recipe can be depending on what ingredients you already have at home. You can adjust the sweetness, add extra crunch, or swap a few ingredients while still keeping the smooth chocolate and hazelnut flavor that makes these bars so comforting.
Another reason this recipe works so well for families is that the bars store beautifully in both the refrigerator and freezer. They can be sliced ahead for snacks, packed into lunch boxes, or served as an easy dessert after dinner without needing any last-minute preparation.
Serves: 12 people
This recipe makes about 12 medium bars, depending on how large you slice them. You can also cut them into smaller squares for snack trays, dessert platters, or meal prep during the week.
Ingredients You’ll Need
Base Layer
- 1 1/2 cups rolled oats
- 1 cup roasted hazelnuts
- 1/4 cup unsweetened cocoa powder
- 1/4 teaspoon sea salt
- 2 tablespoons maple syrup
- 3 tablespoons melted coconut oil
- 1 teaspoon vanilla extract
Chocolate Hazelnut Filling
- 1 cup roasted hazelnuts
- 1/3 cup dairy-free chocolate chips, melted
- 1/4 cup maple syrup
- 1/4 cup coconut cream
- 2 tablespoons cocoa powder
- 1 teaspoon vanilla extract
- Pinch of sea salt
Chocolate Topping
- 1 cup dairy-free chocolate chips
- 1 tablespoon coconut oil
Optional Toppings
- Chopped hazelnuts
- Flaky sea salt
- Shredded coconut
- Mini dairy-free chocolate chips
Pro Tips
- Roast the hazelnuts for a few extra minutes if you want a deeper nutty flavor throughout the bars. Warm toasted hazelnuts create a richer taste and blend more smoothly into the filling.
- Use parchment paper in the pan so the bars lift out easily after chilling. This small step makes slicing cleaner and prevents the chocolate topping from cracking too much.
- Blend the hazelnut filling until very smooth for the creamiest texture possible. Scraping down the sides of the food processor several times helps everything combine evenly.
- Chill the base layer before adding the filling so the layers stay more defined and easier to slice later. A cold base also helps prevent the filling from soaking into the crust.
- Let kids help sprinkle toppings over the bars before chilling because it is an easy kitchen task with very little mess. This recipe works especially well for family cooking since there is no baking involved.
- Store the bars chilled at all times because the coconut oil softens quickly at room temperature. Keeping them cold helps the texture stay firm and smooth for serving.

Substitutions and Variations
Make It Nut-Free
Use sunflower seeds instead of hazelnuts for a similar texture with a slightly different flavor. The bars will still stay creamy and rich while being more allergy-friendly for some families.
Boost the Chocolate Flavor
Add an extra tablespoon of cocoa powder or a little espresso powder to deepen the chocolate taste. These small changes make the bars feel even richer without adding much extra sweetness.
Change the Sweetener
Swap the maple syrup for agave syrup or date syrup if preferred. Each option creates a slightly different flavor while still helping the layers stay soft and smooth.
Add More Crunch
Mix chopped hazelnuts or cacao nibs into the filling before chilling the bars. This gives the bars extra texture and creates a little crunch in every bite.
Make Them Lighter
Use dark dairy-free chocolate with less sugar and reduce the maple syrup slightly for a less sweet version. The bars will still taste rich and creamy while feeling lighter for everyday snacking.
Make Ahead Tips
These No-Bake Vegan Chocolate Hazelnut Bars are perfect for making ahead because the texture becomes even better after a few hours in the refrigerator. I usually prepare them the night before serving so the layers have enough time to firm up properly and develop a richer chocolate flavor.
You can make the base and hazelnut filling a day in advance and keep the pan covered in the refrigerator before adding the final chocolate topping. Splitting the recipe into smaller steps can make preparation feel easier on busy weekdays or during holiday baking seasons.
The bars also freeze very well for longer storage. Slice them before freezing and place parchment paper between layers so they stay easy to separate later when you only want a few pieces at a time.
When ready to serve, let the bars sit at room temperature for about 10 minutes to soften slightly for the best creamy texture. Keeping a batch in the freezer makes it easy to have a quick homemade dessert or snack ready whenever needed.
Instructions
Step 1: Prepare the Pan
Line an 8×8-inch baking pan with parchment paper, leaving extra paper hanging over the edges for easy lifting later. This helps the bars release cleanly and makes slicing much simpler after chilling.
Step 2: Make the Base Layer
Add the rolled oats, roasted hazelnuts, cocoa powder, and sea salt to a food processor. Pulse several times until the mixture becomes crumbly and finely ground without turning into a paste.
Step 3: Add the Wet Ingredients
Pour the maple syrup, melted coconut oil, and vanilla extract into the food processor with the dry ingredients. Blend until the mixture begins to stick together slightly when pressed between your fingers.
Step 4: Press the Base into the Pan
Transfer the base mixture into the prepared pan and press it down firmly into an even layer using a spatula or the back of a spoon. Place the pan in the refrigerator while you prepare the filling so the crust can firm up slightly.
Step 5: Blend the Hazelnut Filling
Add the roasted hazelnuts, melted dairy-free chocolate chips, maple syrup, coconut cream, cocoa powder, vanilla extract, and sea salt to the food processor. Blend until the filling becomes smooth, creamy, and evenly mixed, stopping to scrape down the sides as needed.
Step 6: Add the Filling Layer
Spread the chocolate hazelnut filling evenly over the chilled base layer. Smooth the top carefully with a spatula so the bars look even and neat after slicing.
Step 7: Melt the Chocolate Topping
Place the dairy-free chocolate chips and coconut oil into a microwave-safe bowl or double boiler. Heat gently and stir until the chocolate becomes smooth and glossy without overheating.
Step 8: Finish and Chill the Bars
Pour the melted chocolate topping over the hazelnut filling and spread it evenly across the surface. Sprinkle on any optional toppings, then refrigerate the bars for at least 2 hours or until fully firm before slicing and serving.
Serving Suggestions
These chocolate hazelnut bars taste especially good served slightly chilled with coffee, hot tea, or oat milk. The creamy filling and rich chocolate topping pair nicely with simple drinks that balance the sweetness.
I also like cutting the bars into smaller squares for lunch boxes or snack trays during busy weeks. They hold together well once chilled and make an easy homemade treat for both kids and adults.
For dessert platters or gatherings, serve the bars with fresh strawberries, raspberries, or sliced pears. The fresh fruit adds brightness and helps balance the rich chocolate flavor beautifully.
You can also crumble a small piece over dairy-free yogurt or smoothie bowls for extra texture and sweetness. This turns a simple breakfast into something that feels a little more comforting and filling.
These bars work well for holiday dessert trays because they can be prepared ahead and sliced neatly before guests arrive. A light sprinkle of flaky sea salt on top can make them feel even more special for celebrations.
If you want a richer dessert, serve the bars with a drizzle of warm dairy-free chocolate or a spoonful of hazelnut butter on the side. The extra topping creates an even creamier texture while keeping the recipe simple and comforting.
Leftovers and Storage
Store the bars in an airtight container in the refrigerator to keep the layers firm and fresh. I like placing parchment paper between stacked layers because it prevents sticking and keeps the chocolate topping smooth when serving later.
These bars stay fresh in the refrigerator for up to one week, making them helpful for meal prep and quick homemade desserts during busy days. The flavor often becomes even richer after the first day as the chocolate and hazelnut layers settle together.
For longer storage, freeze the sliced bars in a freezer-safe container for up to three months. Freezing them in a single layer first helps keep the chocolate topping from cracking too much once stacked.
When ready to eat, let the bars thaw in the refrigerator or sit at room temperature for about 10 minutes before serving. This slight softening helps bring back the creamy texture while still keeping the layers firm enough to hold their shape.
Avoid leaving the bars out in warm kitchens for too long because the coconut oil softens quickly at room temperature. Keeping them chilled helps preserve the smooth texture and neat appearance.

Recipe FAQ
Can I use another type of nut instead of hazelnuts?
Yes, almonds, cashews, or walnuts can work well in this recipe if needed. The flavor will change slightly, but the bars will still stay creamy and rich. Roasted nuts usually create the best texture and deepest flavor.
Do I need a food processor?
A food processor is the easiest option because it blends the hazelnuts into a smooth filling. A high-powered blender can also work, but you may need to stop often and scrape down the sides. The smoother the filling, the creamier the bars will taste.
Can I freeze these bars?
Yes, these bars freeze very well for longer storage. Keep parchment paper between layers and store them in a sealed freezer-safe container. Let them soften slightly before serving for the best texture.
Why is my filling too thick?
The filling may become thick if the hazelnuts are not blended long enough or if too much cocoa powder is added. Adding a small spoonful of coconut cream can help smooth the mixture if needed. Warm ingredients also blend more easily than cold ones.
Can I make these bars less sweet?
Yes, you can reduce the maple syrup slightly or use darker dairy-free chocolate with less sugar. The bars will still taste rich because the hazelnuts and cocoa provide plenty of flavor on their own.
How do I slice the bars neatly?
Use a sharp knife and wipe it clean between cuts to keep the layers smooth and even. Chilling the bars completely before slicing also helps prevent cracking and messy edges. Small gentle cuts work best.
Are these bars good for meal prep?
Yes, these bars are excellent for meal prep because they stay fresh for several days and hold together well in the refrigerator. You can portion them ahead for snacks, desserts, or lunch boxes during busy weeks.
