Step-by-Step Instructions
Preheat and Prepare the Pan
First, preheat your oven to 350°F (175°C). This step warms the oven for even baking. Next, grab an 8x8 inch (20x20 cm) baking pan. Line it with parchment paper. Leave some paper hanging over the edges. This makes it easy to lift out the fudge bars later.
Combine Chocolate and Coconut Oil
In a large bowl, add 1 cup of dark chocolate chips and 1/2 cup of melted coconut oil. Stir them together until smooth. This mix should be glossy and well combined. The coconut oil helps create a rich fudge texture.
Mix in Sugar, Eggs, and Vanilla
Next, add 3/4 cup of granulated sugar. Mix it in until fully blended. Now, crack in 2 large eggs, one at a time. After each egg, stir well. Finally, add 1 teaspoon of vanilla extract. This adds a nice, sweet aroma to your fudge bars.
Combine Dry Ingredients
In a separate bowl, whisk together 1/2 cup of all-purpose flour, 1/4 cup of cocoa powder, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. This mix adds structure to your bars. Gradually fold these dry ingredients into the chocolate mixture. Do this until just combined to keep it fudgy.
Fold in Hazelnuts and Chocolate Chunks
Now, gently fold in 1 cup of chopped hazelnuts and 1/2 cup of chocolate chunks. Make sure they are evenly mixed. These add a lovely crunch and extra gooeyness to every bite.
Bake and Cool
Pour the batter into your prepared baking pan. Use a spatula to spread it evenly. Bake for 25-30 minutes. Check with a toothpick; it should have a few moist crumbs when done. Avoid overbaking to keep that fudgy texture. Let the bars cool in the pan for about 10 minutes. Then lift them out using the parchment paper. Transfer to a cutting board to cool completely before slicing into squares.
Tips & Tricks
Ensuring Fudgy Texture
To get that perfect fudgy texture, avoid overbaking your bars. Bake them until a toothpick comes out with a few moist crumbs. This means your bars will stay soft and chewy, not dry. Also, let them cool in the pan for about 10 minutes. This helps them firm up without losing that rich, fudgy feel.
Perfecting Hazelnut Flavor
To boost the hazelnut flavor, toast the chopped hazelnuts before adding them to the batter. Spread them on a baking sheet and toast for about 8-10 minutes at 350°F (175°C). This brings out their nutty aroma and gives a nice crunch. You can also add a splash of hazelnut extract for an extra kick of flavor.
Storing Leftovers Properly
Store any leftover fudge bars in an airtight container. They stay fresh for about a week at room temperature. If you want them to last longer, place them in the fridge. Just remember to bring them back to room temp before enjoying. This keeps the texture nice and fudgy.
Pro Tips
- Use Quality Chocolate: The flavor of your fudge bars largely depends on the quality of the chocolate you use. Opt for high-quality dark chocolate chips for the best taste.
- Don’t Overmix: When combining the dry ingredients with the wet, mix just until combined. Overmixing can lead to a denser texture than desired.
- Storage Tips: Store leftover fudge bars in an airtight container at room temperature for up to a week, or refrigerate for longer freshness.
- Custom Add-Ins: Feel free to customize your fudge bars by adding ingredients like dried fruits, different nuts, or even a swirl of peanut butter for a unique twist.
Variations
Adding Other Nuts
You can switch up the nuts in your fudge bars. Walnuts and pecans add great flavor. They give a nice crunch too. Just use the same amount as hazelnuts. Mix them in the batter just like hazelnuts. This small change can make your bars taste new and exciting.
Vegan Version
You can make a vegan version of these fudge bars. For eggs, use flaxseed meal. Mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit for five minutes to thicken. Use plant-based chocolate chips instead of dark chocolate chips. Coconut oil works well for fat. This way, you keep the rich taste without using any animal products.
Gluten-Free Option
If you need a gluten-free option, swap the all-purpose flour. Use almond flour or a gluten-free flour blend. Make sure to check the labels to confirm they are gluten-free. This will keep the texture soft and fudgy, just like the original recipe. You won’t miss the gluten in these tasty bars!

Freezing Instructions
If you want to save some for later, freezing works great. First, let the fudge bars cool completely. Then, wrap each bar in plastic wrap. After that, place them in a freezer-safe bag or container. They can stay in the freezer for up to three months. When you're ready to enjoy, thaw them in the fridge overnight.
Shelf Life
