1-Bowl Chocolate Hazelnut Cake (Vegan + GF)

Allow me to introduce my absolute new favorite cake.

Chocolaty
Hazelnutty
Vegan
Gluten-Free
1 Bowl

The obsession is real.

This recipe was inspired by my Best Vegan Gluten-Free Chocolate Cupcakes, and my love for Nutella. I mean who doesn’t love Nutella? Even Rhonda loves Nutella. Get on board people.

While there isn’t any Nutella actually in the cake, it has all of the essential components: Creaminess, chocolaty-ness, and loads of roasted hazelnuts!

And to keep things simple, it all comes together in 1 BOWL. Anyone can make this cake. No special mixers, methods, or equipment necessary.

This cake gets extra height from a solid layer of roasted hazelnuts + more on top! They also provide a healthy crunch to the cake, which I happen to adore.

I think you guys are going to LOVE this cake! It’s:

Super moist
Rich
Mega chocolaty
Loaded with hazelnuts
Seriously decadent
Not too sweet
& Simple to make

I think this is a great “everyday” cake with its simple preparation and universally loved flavor profile. However, I could also see it making an excellent cake for birthdays, anniversaries and any upcoming spring celebrations (like Easter!). In other words, make this cake and instantly make a million friends.

Ingredients

US Customary – Metric

CAKE

• 4 Tbsp flaxseed meal (to make flax eggs)
• 10 Tbsp water (to make flax eggs)
• 1 cup unsweetened plain almond milk
• 1 1/2 tsp apple cider vinegar
• 3 tsp baking soda
• 2/3 scant cup maple syrup or agave nectar (sub honey if not vegan)
• 2/3 cup cane or granulated sugar
• 1/2 cup melted coconut oil or vegan butter (such as Earth Balance)
• 1 tsp pure vanilla extract
• 2 cups unsweetened applesauce (or other hearty fruit puree, such as beets)
• 1/2 tsp sea salt
• 1 cup unsweetened cocoa powder (if clumpy, sift)
• 1 cup almond meal (finely ground from raw almonds)
• 1/2 cup gluten-free oat flour (finely ground from raw oats)
• 1 1/2 cups gluten-free flour blend*

FROSTING / TOPPINGS

• 1/2 cup unsweetened plain almond milk
• 1 1/4 cups dairy-free dark or semi-sweet chocolate (chopped)
• 1/4 cup melted coconut oil or softened vegan butter (cut into slices // such as Earth Balance)
• 1 1/4 – 2 cups powdered sugar (ensure vegan-friendliness)
• 1 1/2 cups roasted unsalted hazelnuts

Instructions

• Preheat oven to 350 degrees F (176 C) and butter two 8″ round cake pans (or line 24 muffin tins with paper liners // as original recipe is written // adjust number/size of pans if altering batch size). Dust with gluten free flour and shake out excess.
• Measure out almond milk and add vinegar. Stir and let curdle while moving onto the next step.
• Prepare flax eggs in a large mixing bowl by mixing flaxseed meal and water and let rest for 5 minutes.
• Add baking soda to the almond milk vinegar mixture and stir.
• Add the sugar, maple syrup and almond milk mixture to the flax egg and beat/whisk to combine. Then add applesauce, vanilla, melted coconut oil, salt and mix.
• Add cocoa powder, almond meal, oat flour and gluten free flour and beat/whisk to combine. If the batter appears too thick, add a touch more almond milk, but it should be perfect. It should resemble a semi-thick batter that’s pourable.
• Divide batter evenly between cake pans (if using muffin tins, it should be enough for roughly 24 filling generously 3/4 full // amount as original recipe is written).
• Bake cake for 35-45 minutes or more (cupcakes for about 29-35 minutes) or until a toothpick inserted into the center comes out clean and the top appears dry. Time will vary if you sub ingredients, as well as depending on the size of your pan.
• Let rest in the tin for 15-20 minutes, then carefully run a butter knife along the edges and invert onto cooling racks. Let cool completely.
• FOR FROSTING: Add almond milk to your rinsed out mixing bowl from earlier and microwave for 1 minute. (Alternatively, heat in a saucepan until just simmering and then transfer back to mixing bowl.)
• Immediately add chocolate to warm milk but don’t touch for 3 minutes so it can melt.
• Stir with a wooden spoon to incorporate, then add coconut oil or softened butter and cover. Let rest untouched for another 10 minutes.
• Use your mixer (or a whisk) to beat the mixture together. Then add 1 cup powdered sugar, mix again, and place in fridge to set for 20 minutes. You’ll know it’s ready when you tip it and it’s slow to move.
• Remove from fridge and beat again. If it’s still too thin, add another 1/4 – 1/2 cup powdered sugar (amount as original recipe is written // adjust if altering batch size) and beat until light and fluffy. I found that adding 1 3/4 cups total powdered sugar (amount as original recipe is written // adjust if altering batch size) was perfect. Set aside.
• Transfer the bottom layer of the cooled cake to a serving plate/dish. Spread a semi-generous layer of frosting on the top of the bottom layer and top generously with hazelnuts. Press down with hands to settle them into the frosting (see photo).
• Carefully top with second layer and frost the top generously, then the sides. Using a butter knife yields a smooth surface. It should be the perfect amount of frosting – not too thick, not too thin.
• Add hazelnuts around the perimeter of the top of the cake. Slice and serve.
• Will keep well-covered at room temperature for several days, though best when fresh. Refrigeration not necessary.

Notes

*For this cake, I used the Bob’s Red Mill 1:1 gluten-free flour blend. However, my DIY gluten-free flour blend works well, too!
