These chocolate brownies are rich and gooey, and so delicious. These brownies are mixed up in one bowl. You don't need to beat the butter or sift the flour. We used quality dark chocolate for this recipe as well as dark cocoa powder for intense chocolate flavour. This recipe is so easy to make, you just need few mixing bowls, whisk and spatula to get the batter together. If you intense chocolate sweets, try our recipes for mini chocolate tarts or double chocolate cookies made with spelt flour.

what you need to make fudgy hazelnut brownies

These brownies should be super chocolatey so you need to use quality dark chocolate with high percentage of cocoa solids - preferably higher than 55%. Use chocolate bars and chop in into big chunks so it melts easily and quickly.

In addition, we added a few tablespoons or rich dark cocoa powder which enchance this rich chocolate flavour and gives dark colour to the brownies.

This recipe features whole grain spelt flour, but white spelt flour as well as plain flour will works too. Toasted hazelnuts are always a great addition to any chocolate dessert, so these brownies are not exeption. We added toasted chopped hazelnuts to give extra touch and some crunchiness to these fudgy brownies.

how to make these dark chocolate brownies

For these brownies you will need a few bowls, wire whisk, silicon spatula and square baking pan. The recipe start with toasting hazelnuts in the oven until lightly brown and fragrant. Blitz them in the food processor until finely chopped. Now, continue with the whipping up batter for these rich chocolate brownies:

  1. First mix flour, cocoa powder and salt in one bowl

  2. Chop chocolate bar and together with butter melt over a saucepan of simmering water

  3. Whisk eggs and muscovado sugar using a wire whisk until combined and most of the sugar is dissolved

  4. Pour chocolate mixture into the egg/sugar mixture and whisk to combine

  5. Fold gently dry ingredients and toasted hazelnuts. Your batter is ready for baking.

baking the brownies

Pour the batter into square baking pan and bake for 20 minutes. This batter is enough for 20cm square baking pan and you get 9 large brownies. If you want to double the recipe, bake it in the larger baking pan and increase the baking time for about 5 minutes, maybe more. You can also bake this batter in round baking pan.

Extra baking tip

It is important to keep an eye on the brownies while baking. When the edges are set, the top is shiny and the center is a little jiggly, take them from the oven. The brownies will set while cooling in the pan and firm up.

  6. Pour chocolate mixture into the egg/sugar mixture and whisk until combined.
