Slow cooker brownies are super easy to make. First melt the chocolate, sugar, and butter. With the melted chocolate mixture, eggs, flour, cocoa, and baking powder you make a batter. Pour this into the slow cooker and let it cook on low for 3 hours and 30 minutes.
- Melting chocolate - You melt chocolate au bain-Marie. As a result, it does not burn (which is really not nice ;-)). How do you do that? Take a heatproof bowl and put the chocolate, butter and sugar in it. Bring a pan with a layer of water to the boil and hang the bowl over the water (it should not touch the water). The chocolate and butter will melt because of the warmth released by the steam.
- Sifting - You sieve the flour, baking powder and cocoa, so you don't get lumps. The advantage is that you can make this recipe without a mixer!
- Baking - Turn the slow cooker on the lowest setting for 3 hours 30 minutes for delicious fudgy brownies, with a lid on the crockpot. The heat and steam that are created will make your brownies perfect! You can't make brownies on the highest setting!

Notes
3. Dark brown sugar - The molasses added to this sugar gives it a light caramel flavor. You can replace this with the same amount of regular sugar or light brown sugar, but you won't have that caramel hint.
4. Baking powder - Baking powder provides the airiness in this recipe. You can substitute it with 1 teaspoon of tartaric baking powder. This cannot be replaced by baking soda or self-rising flour (the latter has too little baking powder in the mixture).
5. Store Brownies -
- Room Temperature - Store the brownies in an airtight container (or wrap them in plastic wrap). You can keep them at room temperature for up to 3 days.
- Frozen - If you want to keep them longer, freeze them! Wrap the brownie cubes individually in plastic wrap and put that into a freezer box. You can keep them in the freezer for up to 2 months.
With this batter you make 16 square brownies. The nutritional values are shown per piece of brownie.
