Preheat the oven to 350 degrees.
Next, line an 8x8 baking pan with parchment paper, allowing some paper to hang over the sides.
Then, spray with non-stick cooking spray. (it won't lay down completely until you pour in the batter)
In a small sauce pan, heat the coconut oil, cocoa, chocolate and coffee over low heat. Stir it until melted and smooth. Then set aside and allow to cool.
In a separate bowl, using a hand mixer, beat the eggs, sugar and vanilla for 2 minutes, or until smooth and light in color. Add the melted chocolate to the egg mixture and mix until smooth. Add the cornstarch and mix again until completely smooth and thickened.
Pour the batter in the prepared pan and spread it as evenly as possible.
Bake for 25-30 minutes or until the center is just set. Do not over bake. Cool for at least an hour before cutting into squares. Makes approximately 12 brownies.
