Preheat oven to 350 degrees. Line an 8-inch square baking pan with parchment paper and spray with non-stick baking spray if desired.

Melt the butter and chocolate together in a medium pan over very low heat. Stir together and remove from heat. Let cool for a minute or two. Add the Blood Orange Olive Oil, sugar and vanilla, mix well. Add eggs, one at a time, beating into the mixture rapidly to avoid cooking the eggs. Stir in the salt, cocoa and flour.

Spread the brownie mixture into your prepared baking pan and bake until set, for about 35 to 40 minutes. Cool before cutting with a sharp knife and drizzle with Blood Orange Citrus Syrup before serving if desired.
