To make the Gray Day Cake:
  1. Preheat oven to 350 degrees F. Grease 3 8-inch cake pans with baking spray, set aside.
  2. Whisk cake flour, baking powder, baking soda, and salt in a large bowl and set aside.
  3. Beat butter in a stand mixer with a paddle attachment on high for 1 minute. Add sugar and raise speed, beating for 2 minutes. Scrape the sides and bottom of the bowl down as needed.
  4. Add egg whites and beat for an additional 2 minutes, scraping the bowl when needed.
  5. Mix in sour cream and vanilla, followed by dry ingredients, beating until just combined. Add milk in a slow steady stream followed by the black food gel. Add in ground and quartered Oreos. Use a rubber spatula to thoroughly scrape the sides and mix the batter.
  6. Divide batter between pans and back for 25 to 35 minutes, rotating halfway. A toothpick inserted should come out clean or with a few moist crumbs. Allow cakes to cool in pans for 5 minutes, before inverting them onto a wire rack to cool completely.
To make the Feeling Blue Frosting:
  1. In the bowl of a stand mixer fitted with a paddle attachment, beat butter on medium-high speed until, fluffy and pale in color, about 3 minutes. Scrape the sides and bottom of the bowl. Add the powdered sugar, followed by the cream, vanilla, salt, and blue gel. Raise speed for high and beat for another 2 to 3 minutes. Beat in ground Oreos, mixing to combine. Don't over beat the Oreo crumbs. Refrigerate until ready to use.
To make the Cloudy Frosting:
  1. In the bowl of a stand mixer fitted with a paddle attachment, beat butter and shortening on medium-high speed until smooth, about 2 minutes. Add powdered sugar, cream, vanilla, salt, and black food gel. Raise speed to high and beat to combine. Scrape the bowl as needed. Beat in Oreo crumbs.
To assemble the Rainy Day Cake:
  1. Spoon a bit of frosting onto a cake board. Secure the first cake layer and apply some of the Feeling Blue Frosting, apply the second layer and repeat. Top with the final third layer. Do a crumb coat, chill for 10 minutes, and do a final thicker coat of Feeling Blue Frosting. Apply a thin layer of Cloudy Frosting onto top of cake. Use an ice cream scoop for apply frosting in a circular formation.
