Preheat oven to 180°C. Line base and two sides of a 20x20 cm tin with a single piece of baking paper.
Add oil and sugar to a large saucepan. Place pan over medium heat for 30 seconds, just until you see tiny bubbles in the oil.
Remove pan from heat, add chocolate and stir until melted. Add Moccona, cocoa, vanilla, and salt. Stir well.
Add eggs and quickly stir to incorporate (don’t worry if the batter looks split at this stage). Add almond meal and baking powder and vigorously stir once more, until mixture is smooth and shiny.
Scrape batter into prepared tin and sprinkle with almonds.
Bake 12 - 15 mins until brownie is firm on top and a skewer inserted into the centre comes out clean. Leave to cool in pan for 5 mins. Transfer to a rack and cool completely before cutting.
