Equipment

  • 2 cake pans
  • 1 piping bag
  • 1 size 10 round piping tip

Ingredients
  

Cake

  • 3 cups oat flour
  • 1 cup coconut sugar
  • cup cocoa powder
  • 1 ½ tsp baking soda
  • 2 tsp baking powder
  • cup black coffee or 1 tbsp espresso powder dissolved in 3 tbsp hot water
  • 1 ½ cup applesauce
  • 1 cup plant milk

Frosting

  • 12 oz cream cheese
  • 16 tbsp butter
  • 3 cups powdered sugar

Natural Coloring

  • 5 tbsp cherry juice see notes
  • 2.5 tbsp matcha powder

Instructions
 

Cake

  • Preheat the oven to 350℉ and lightly grease two round cake pans.
  • Combine oat flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl.
  • Make a well in the center of the dry ingredients, then pour in the applesauce, plant milk, and brewed coffee.
  • Fold gently to fully combine.
  • Divide the batter between the two cake pans and bake for 25-30 minutes or until a toothpick comes out clean when inserted into the center of the cake.

Frosting

  • Add vegan butter and cream cheese to a large bowl and beat on high with a hand mixer until fully combined.
  • Add powdered sugar in three batches to avoid making a huge mess!
  • Separate about ⅛ of the batch - this will be used for the green frosting.
  • Add 5 tbsp cooked cherry juice or sub another pink dye (see ideas above) to the larger batch of frosting and incorporate with hand beater on low.
  • Add matcha powder to the smaller sized batch of frosting and stir thoroughly to combine.

Assembly

  • Wait for the cakes to cool completely before frosting!
  • Add the first cake the your final serving platter. Place the platter on a lazy susan, if available.
  • Add about ¼ the batch of pink frosting on top of th efirst cake and spread into one even layer.
  • Carefully place the second cake on top.
  • Use the rest of the pink forsting to cover the top and sides of the layered cake. Be sure to create a smooth surface on top for piping letters.
  • Add the green frosting to a piping bag fit with a size 10 round tip.
  • Pipe "Happee Birthdae Harry" in three separate lines on top of the cake.
  • Cut a curved line into the cake to fully replicate the visual we get in the film scene! The line should curve between the P and E in "Happee," the H and D in "Birthdae," and the H and A in "Harry." :)

Notes

For the pink frosting
There are a couple of options for this one, but I used roasted cherry juice. Frozen cherries release their juices as they thaw, and the juices thicken as the cherries continue to cook at higher temperatures. 2 cups of cherries release about 5 tablespoons of juice, which is enough for this recipe!
 
You could also use freeze dried strawberries or freeze dried raspberries as a natural dye, I’ve had great results with both in the past! If you go this route, you’ll need to blend up the strawberries or raspberries - I LOVE using my coffee grinder (linked here) for small-batch blending like this.
