Preheat oven to 350F. Add the almond flour, cocoa powder, baking powder and salt to a bowl and whisk to combine, then set aside.In a separate bowl, add in the eggs and Swerve. Beat using a hand mixer for 2 minutes.
Mix in the nutella, butter and vanilla. Add in the dry ingredients and chocolate chips and mix using a spatula.
Pour into a 9" x 9" baking dish lined with parchment paper and bake for 20-25 minutes, then allow to cool for at least 10 minutes before cutting into them.
I like to add a dusting of Swerve confectioners over the top for a little added sweetness, but you can omit if you'd like.
If you prefer them more on the fudgy side, bake them closer to 20 minutes. If you like a more cakey brownie, bake a little longer.
