Ingredients You’ll Need

The beauty of this recipe lies in its simple yet thoughtfully chosen ingredients. Each one plays a crucial role—from the chickpeas adding protein and moisture, to the oats contributing a lovely texture and fiber. Every element works in harmony to bring out that classic brownie richness while keeping it on the healthier side.

1 cup old fashioned rolled oats (or oat flour): Provides a hearty base and subtle nuttiness, essential for texture and fiber.
1 (15 oz) can of chickpeas (liquid included): A surprising yet brilliant substitute that adds protein and keeps the brownies moist.
1/2 cup milk of choice: Adds creaminess and helps blend the ingredients smoothly.
1/8 cup oil (canola recommended): Keeps the brownies tender and perfectly moist.
1 tsp apple cider vinegar: Reacts with the baking soda for a light, airy crumb.
1 tsp vanilla extract: Enhances the chocolate flavor with its warm, sweet aroma.
1/2 cup unsweetened cocoa powder: The star ingredient delivering deep chocolate richness without added sugar.
1/4 cup cornstarch: Helps bind and soften the texture, making these brownies wonderfully tender.
1/4 cup + 1 Tbsp granulated sweetener of choice: Adds gentle sweetness without overpowering the natural flavors.
3/4 tsp baking powder: Supports the rise, giving a perfect balance between fudgy and cakey.
3/4 tsp baking soda: Works with apple cider vinegar for a light texture.
1/4 tsp salt: Enhances all flavors and balances the sweetness.
1 cup hazelnuts (for frosting): Adds a rich, nutty flavor that pairs beautifully with chocolate.
1/4 cup agave or sticky sweetener of choice (for frosting): Sweetens the frosting naturally while keeping it smooth.
2 Tbsp oil (canola recommended for frosting): Contributes richness and creamy consistency to the frosting.
1 Tbsp granulated sweetener of choice (frosting): A little extra sweetness for the hazelnut topping.
1/4 tsp salt (frosting): Brings out the nutty and sweet notes in the frosting.
1/2 cup plain yogurt of choice (preferably Greek, for frosting): Adds tang and makes the frosting fluffy and luscious.

How to Make Healthy Chocolate Hazelnut Brownies Recipe

Step 1: Prepare Your Pan and Preheat the Oven

Start by preheating your oven to 325°F. Grease an 8 x 8-inch square pan or line it with parchment paper for easy removal later. Getting this step right ensures your brownies bake evenly and come out perfectly intact.

Step 2: Blend the Base Ingredients

Add the old fashioned rolled oats (or oat flour) and the entire can of chickpeas including the liquid into a food processor or blender. Blend until completely smooth—that’s the secret to a fudge-like consistency without any funky texture.

Step 3: Mix Wet Ingredients In

To the oatmeal-chickpea blend, add the milk, oil, apple cider vinegar, and vanilla extract. Blend again just until everything is incorporated. This keeps the mixture smooth and ensures your brownies will be moist and flavorful.

Step 4: Combine Dry Ingredients

In a large bowl, whisk together the cocoa powder, cornstarch, sweetener, baking powder, baking soda, salt, and oat flour if you’re not already using it. This dry blend sets the foundation for the perfect crumb and chocolaty depth.

Step 5: Bring It All Together

Pour the blended wet base into the bowl with your dry ingredients. Stir gently but thoroughly until everything is evenly combined. No lumps here means an even bake and consistent texture throughout your brownies.

Step 6: Bake the Brownies

Pour the batter into your prepared pan and spread it out evenly. Bake for about 28 to 29 minutes. You’re looking for a toothpick inserted in the center to come out with just a little bit of wet batter, but no crumbs – that’s the brownie sweet spot between fudgy and cakey.

Step 7: Create the Hazelnut Frosting

While the brownies are baking, blend together the hazelnuts, agave, oil, sweetener, and salt in your food processor until completely smooth. Scrape down the sides as needed—patience here pays off with a silky frosting!

Step 8: Whisk in the Yogurt

Transfer the hazelnut mixture to a large bowl and whisk in the yogurt by hand or with an electric mixer until the frosting becomes fluffy and light. Pop it in the refrigerator for at least an hour to thicken up and ensure it spreads beautifully.

Step 9: Frost and Enjoy

Once the brownies have cooled completely, spread your thickened hazelnut frosting generously over the top. For an extra-special touch, sprinkle chopped hazelnuts or a few chocolate bits on top before slicing and sharing. You’ll be amazed at how indulgent yet nourishing these brownies feel.

Garnishes

Adding a handful of chopped toasted hazelnuts or a light dusting of cocoa powder takes these brownies to the next level. It’s a lovely way to add crunch and a visual pop that makes everyone’s eyes light up.

Side Dishes

These brownies pair beautifully with a scoop of dairy-free vanilla ice cream or a dollop of whipped coconut cream for those extra cozy moments. A cup of your favorite coffee or tea complements the deep chocolate and nutty flavors perfectly.

Creative Ways to Present

Try serving these brownies as mini bites on a dessert platter alongside fresh berries for a colorful contrast. You can also cut them into elegant squares and wrap individually for gifting or party favors. They’re a wonderful conversation starter wherever you bring them!

Make Ahead and Storage

Storing Leftovers

Keep any uneaten brownies in an airtight container at room temperature for up to three days. This preserves the moist texture and keeps the frosting fresh. If your kitchen is warm, storing them in the fridge is a safe bet to keep everything intact.

Freezing

For longer storage, wrap brownies tightly in plastic wrap and place them in a freezer-safe container or bag. They can freeze well for up to two months without losing their deliciousness. Thaw in the refrigerator overnight before enjoying.

Reheating

To revive the fudgy texture, warm your brownies for about 15 seconds in the microwave or pop them briefly in a low oven. This warms up the chocolate and makes the frosting soft and inviting again.

FAQs
