1) Preheat your oven to 350ºF, and grease and line a 8×8 pan with butter and parchment paper.

2) Boil water on the stove in a pot. Once boiling place a heatproof bowl over top of the pot and add in the butter, chocolate, orange juice, and cocoa powder. This forms a double boiler.

3) Stir the mixture continuously, with the heat still on, until the butter and chocolate have fully melted and the mixture is smooth. Remove from heat and let cool until warm (no longer hot).

4) Add in sugars and mix vigorously with a whisk (it will be grainy). Then, add in the egg and vanilla and mix until combined.

5) Finally add in flour, salt, and zest and stir until no dry patches remain. Pour the batter into the prepared pan and smooth out with an offset spatula or spoon.

6) Slice oranges into 5 thin discs and then 10 halves (you will have one extra). Toss the now 9 crescent slices in sugar and place on top of the brownies.

7) Bake the brownies for 50-60 minutes until crackly on the top and only small amounts of batter remain on a toothpick when inserted.

8) Let fully cool at room temperature for 30 minutes and then in the fridge for another 30. Slice, serve, and enjoy!
