Hazelnut Brownies

gluten-free vegan hazelnut brownie

Freshly inspired by these delicious Brookies I decided to make another brownie treat. I combined two of my favorite things: chocolate + hazelnut butter and ended up with the most delicious hazelnut brownies. Hazelnut butter does wonders in baked goods in terms of flavor and these brownies turned out moist, smooth, and velvety, deeply flavorful and “buttery”. With some almond milk or a cup of coffee — absolutely more-ish...

What these gluten-free vegan hazelnut brownies are not is photogenic! :D These are definitely a homemade messy kind of a treat, but those are also often the best kinds of treats anyhow, right? ;)

They’re hard to cut gracefully and so I highly recommend eating them with your hands and not with a fork. I’m usually a fork in hand for dessert kind of person, but biting into one of these brownies is dreamy so I didn’t mind… For easier cutting let them sit out a little on the counter after the frosting has set so that the frosting is softer.

A few quick tips for making these hazelnut brownies

  • I used hazelnut butter here because of the beautiful flavor and smoothness, but I’m fairly certain these will work great with other nut or seed butters (especially almond, pecan, or peanut butter), though of course keep in mind that with each one the flavor and sweetness levels will be quite different.
  • Also, feel free to improvise with toppings (or skip if you prefer). I used a mix of chopped hazelnuts, pistachios, and dried raspberries I had on hand and loved the flavors and light crunch and little bursts of color that they added to these brownies.
  • If you prefer to make your own chocolate for the frosting, feel free to use some of this vegan “magic shell” recipe instead of the melted dark chocolate.

Last but not least, if you’re looking for other ideas to use up some of the leftover hazelnut butter, here are a few of my favorite recipes:

Delicious moist and rich baked hazelnut brownies with a creamy chocolate hazelnut frosting. Gluten-free and vegan.


Brownies — Dry Ingredients

Brownies — Wet Ingredients

  • ½ cup unsweetened vanilla almond milk
  • ¼ cup natural creamy hazelnut butter**
  • 1 tsp pure vanilla extract

Chocolate Hazelnut Frosting

  • 7 tbsp hazelnut butter
  • 5 tbsp melted vegan dark chocolate


  • a small handful each: chopped pistachios, chopped hazelnuts, chopped dried raspberries


  1. Preheat oven to 350F. Line a baking dish that’s roughly 7″ x 4.5″ (or a dish of a similar size) with parchment paper along the base and edges and set aside.
  2. Stir all dry ingredients together in a medium-sized bowl. Add wet ingredients and mix thoroughly to combine everything with a wooden spoon. Transfer the brownie mixture into the prepared baking dish and flatten the top with the back of a spoon.
  3. Bake in pre-heated oven for approximately 16 minutes until the top feels springy when lightly touched. Remove from oven and cool completely on a wire rack (don’t remove the brownies from the tray at this stage).***
  4. Once fully cooled, prepare the chocolate hazelnut frosting by stirring together all frosting ingredients in a small bowl. Spread this mixture over the brownies in the tray (it’ll be quite runny at this stage). Sprinkle with toppings (if using) and place the tray in the fridge for about an hour (or longer) for the chocolate frosting to firm up. Once it seems like it solidified a little you can remove the brownies from the fridge, cut into squares, and enjoy! Store leftovers in the fridge.


*Or cocoa powder. I just used what I had on hand.

**The hazelnut butter should be very creamy and runny. For best results use a fresh jar of hazelnut butter and stir the contents really thoroughly for the oil and nut butter to become fully incorporated.

***It’s important that the brownies are fully cooled in order for the chocolate frosting (step 4) to firm up (as otherwise it’ll remain runny).
