Preheat oven to 400 degrees F.

Spray an 8x8 inch baking dish with cooking spray and set aside.

In a large bowl or stand mixer fitted with a whisk attachment, beat together all cake ingredients on medium speed for about 4 minutes, scraping down the sides as needed. Pour into prepared baking dish.

While batter whips, add chocolate chips and coffee granules to a microwave-safe bowl and heat for 30 seconds in the microwave. Remove and stir, if chocolate chips haven't completely melted, continue to microwave on 10-second intervals until fully melted.

Drop small spoonfuls of melted chocolate on top of the cake batter and use a rubber spatula or knife to run through them and create a marbled swirl effect.

In another small bowl, combine the topping ingredients, stir until evenly mixed, then sprinkle over the cake.

Bake for 20 to 25 minutes until a toothpick inserted into the center comes clean. Try to insert where there isn't any chocolate because the chocolate will be gooey even once the cake is cooked. Remove from oven and slice and serve.
