Instructions
To make the Galaxy Bundt Cake:
  1. Preheat oven to 350 degrees F. Grease an 8-cup bundt pan with baking spray, set aside.
  2. Sift cake flour, baking powder, and salt together. Beat butter in a stand mixer fitted with a paddle attachment. Once smooth, add sugar and oil, beating on medium-high speed until pale and aerated, about 2 minutes, scrapping bowl and paddle as needed. Lower speed, add in vanilla, followed by eggs and egg yolks, adding one at a time. With mixer on low, add dry ingredients in 3 additions, followed by buttermilk in 2 additions, beginning and ending with the dry ingredients. Give batter a stir by hand to ensure proper incorporation and nothing sticks to the bottom.
  3. Divide batter into food separate bowls, tint to desired shade. Use a spoon to dollop batter into pan. See note about galaxy swirl. Marble batter by running a butter knife through the batter. Tap pan against counter to remove air bubbles. Bake for 60 to 70 minutes, rotating halfway. The cake should be pulling away from the pan and toothpick inserted should come out clean with a few moist, not wet, crumbs. Rest in pan for 15 minutes before inverting onto a wire rack to cool completely.
To make the Galaxy Swirl Cake Base:
  1. Preheat oven to 350 degrees F. Grease one 8-by-8 pan and one 9-by-9 pan with baking spray, set aside. Sift cake flour, baking powder, and salt together. Beat vegetable oil and granulated sugar in a stand mixer fitted with a paddle attachment. Once combined, add eggs one at a time beating well after each addition. Beat in vanilla. With mixer on low, add dry ingredients in 3 additions, followed by buttermilk in 2 additions, beginning and ending with the dry ingredients. Divide batter evenly into 5 different bowls. Tint to desired shade. Use a spoon to dollop batter into pan. See note about galaxy swirl. Marble batter by running a butter knife through the batter. Tap pan against counter to remove air bubbles. Bake for 45 to 50 minutes, rotating halfway. The cakes should be pulling away from the pans and toothpick inserted should come out clean with a few moist, not wet, crumbs. Rest in pans for 15 minutes before inverting onto a wire rack to cool completely.
To make the Oreo Frosting:
  1. In a stand mixer fitted with a paddle attachment, beat shortening and butter on medium-high speed until well blended, about 3 minutes. Add in vanilla. Gradually add powdered sugar on low speed, adding a bit of milk when mixture gets too thick. Scrape bowl and paddle as needed. Sprinkle in salt. Raise speed to medium-high beat for final 30 seconds. Beat in Oreo crumbs. Tint for black gel until desired gray color is reached. Repeat process a second time for the next batch. Refrigerate until assembly.
To assemble the Ancient Alien Cake:
  1. Use a large platter and secure the 9-by-9 cake on the bottom. Apply even layer of Oreo Frosting. Secure in wooden skewers. Top with 8-by-8 cake, apply frosting. Finally top with bundt cake. Apply another layer of Oreo Frosting, filling in the gaps. Refrigerate for 15 minutes. Apply a thicker layer. Refrigerate for 10 minutes, and smooth out surface.
Notes
Note about marbling: I used 4 colors for the bundt cake and 5 colors for the cake layers, this was intentional. Because of the shape of the bundt cake, using the extra color would've been an extra step without a lot of visual differentiation. On straight linear surfaces, like the 8-by-8 and 9-by-9 layers, the extra color is seen. When marbling, don't layer like colors on top of each other. Ie: don't put purple next to pink and green next to blue. Spooning the batter in layers ensures a natural but randomized look: ie dollop a layer of all black followed by a dolloped layer of blue, etc. A butter knife is the best tool for swirling the batter. After swirling, tap the batter against the counter, this will eliminate air bubbles.
