Instructions

1. Preheat the oven to 300ºF. Grease a 9 1/2″ x 11″ pan.
2. In a mixer fitted with a whisk attachment, beat the eggs at medium speed until fluffy and light yellow. Add both sugars. Add remaining ingredients, and mix to combine.
3. Pour the batter into the prepared pan and bake for 45 minutes. Check for doneness with the tried-and-true toothpick method: a toothpick inserted into the center of the pan should come out clean. When it’s done, remove to a rack to cool. Resist the temptation to cut into it until it’s mostly cool.
4. While the brownies are cooking, prepare the frosting. In a medium bowl, use a spatula to combine all ingredients for the frosting together. Once roughly combined, use an electric mixer on medium speed to beat the frosting until smooth, about 2 minutes. Set aside.
5. Once the brownies are cool, remove them from their pan and place on a cutting board, face up. Cut the width into sixths and the length into thirds. Keep brownies together so it is easy to spread frosting. Spoon the frosting out onto the brownies and spread evenly, coating out to the edges.
6. Sprinkle crushed oreos over the frosting, again coating evenly. Then, dust more instant coffee powder over the top. Finally, sprinkle a good amount of sea salt over the entire thing. Carefully pull apart and enjoy!
