INSTRUCTIONS:
In a small saucepan, melt chocolate chips, EVOo, and espresso powder over low heat. Stir occasionally until chips are melted and smooth.
In a stand mixer or medium bowl, using a hand-mixer, whisk the eggs and sugar together until light and fluffy. This should take about 4-5 minutes. Whisk in the vanilla.
In a small bowl, sift together the cocoa powder, flour, baking powder, and salt.
Add the melted chocolate mixture to the egg mixture and gently fold in. Add the dry ingredients and mix just until combined.
Allow the batter to sit for 30 minutes.
Preheat oven to 350F degrees. Line two baking sheets with parchment paper or a non-stick baking mat. Scoop cookies by the heaping (or 2) tablespoon. Roll and then gently press down.
Bake for 10 minutes or. Until the cookies look a bit crackly all over and the center is set. Remove from oven and let the cookies cool for 2-3 minutes on the baking sheet before removing to a cooling rack to cool completely. Sprinkle with salt if desired. Serve warm or room temperature.
