Instructions
Preheat the oven to 325 degrees.
In a small microwave safe bowl, melt the dark chocolate, unsweetened chocolate and butter together by heating on high and stirring every 30 seconds. Set aside to cool.
With an electric mixer, beat the egg, espresso and vanilla in mixing bowl. Add sugar and beat for about two minutes or until mixture thickens slightly and becomes a little paler. Stir in the cooled melted chocolate mixture.
Mix together the oat flour, baking powder and salt and stir until smooth. Stir into the chocolate mixture.
At this point the mixture should be cool. If it is still at all warm, wait before folding in the chocolate chips. Also, mixture will thicken slightly as it stands and cools, so if you feel it's too thin to scoop cover it and let it sit at room temperature for about 10 more minutes.
Using a large cookie scoop or a little less than a ¼ cup measure, scoop out 6 mounds of dough onto the parchment lined baking sheet.
Bake at 325 for 10-12 minutes. Do not overbake. Allow the cookies to cool on the baking sheet for about 5 minutes, then transfer to a wire rack.
Notes
Cocoa Butter Version: I've only made this one twice, and I'm not sure it's worth buying extra cocoa butter for, but the cookies are good. 80 grams Navitas cocoa butter, 28 grams of unsalted butter, 5 grams cacao powder (About 2 teaspoons), 1 large egg, ½ tablespoon instant espresso powder, ½ teaspoon vanilla, 75 grams sugar, ⅓ cup oat flour, ½ teaspoon cornstarch, ½ teaspoon baking powder, ¼ teaspoon salt, ½ cup bittersweet chocolate chips. Technique is same as above, but you melt together cocoa butter and butter and stir in cacao to make the chocolate mixture. From there you beat the eggs etc.
