Today's post is featuring one of my favorite characters from one of my favorite shows.
Everyone say 안녕하세요 to today's recipe!
This is a roll cake that is Lady Rainicorn themed. This cake is a little more ambitious than the Pokéball cupcakes from last week, but it is totally worth the work.
Hope you can give it a try!
Tl;dr? There's a video tutorial at the bottom!
Inventory
For the Decorating Paste:
- 1/2 cup plus 1.5 tbsp flour
- 1 stick butter
- 1/2 cup powdered sugar
- 2 egg whites
For the Cake:
- 4 eggs, separated
- 1 tsp cream of tartar
- 1/2 cup sugar
- 3 tbsp plus 1 tsp butter
- 3/4 cup flour
For the Filling:
- 1 cup heavy whipping cream
- 1-2 tbsp powdered sugar
- 1 tsp vanilla
- fruits of your choice (I used strawberries, blueberries, and pineapple)
You'll also need an image to trace: I drew out a more simplified version of Lady Rainicorn. I'll try to link up the picture here.
But feel free to draw your own or print something else!
Directions
1. For the decorating paste: Cream the 1/2 cup powdered sugar and stick of butter in a bowl with a hand mixer (or stand mixer, or whatever you have!)
2. Slowly add the egg whites and mix. Then add the flour.
3. Once mixed well, divide the dough into 5 small bowls. Dye each bowl of dough a different color. I used black as an outline, then a pinkish-purple, blue, green, and yellow. You can use gel, liquid, or powder food coloring.
4. Add the different colors into piping bags or sandwich bags. Place your image underneath a sheet of parchment paper on the baking pan. Snip a small amount from the corner of the bag with black dough, and carefully trace out the outline.
5. Put the pan in the freezer for a few minutes to firm up. After the outline is firm, trace in the pink color. Repeat the freezing and tracing steps for each color, and then leave the pan in the freezer until you're ready to bake the cake.
6. Preheat the oven to 390°F.
7. For the sponge cake: Separate the 4 eggs. Add 1 tsp cream of tartar and 1/4 cup sugar to the bowl of egg whites.
8. Mix until the egg white form firm peaks. This will take a few minutes. Set aside.
9. In the bowl with the yolks, add 1/4 cup sugar and mix until the color is light (you can use the same beater from the egg white mixture, you don't need to wash it off first).
10. Gently fold the egg white mixture into the yolk one. Do this in a few batches and be gentle not to deflate the egg whites too much.
11. Fold in 3/4 cup flour and 3 tbsp + 1 tsp melted butter to the batter in 2 batches. Make sure the melted butter isn't too hot.
12. Take the pan out of the freezer, and pour the batter into the pan, being careful to fill in all the spots around the image. Drop the pan onto the counter a few times to get rid of any air bubbles.
13. Bake at 390°F for 7 minutes. This cake cooks fast, so keep an eye on it. You don't want to overcook it, or else it will become dry and can crack when you try to roll it!
14. After taking the cake from the oven, cut around the edges to make sure the cake isn't stuck to the pan anywhere. Flip the cake upside-down onto another parchment paper lined pan.
15. Gently peel away the other piece of parchment paper to expose your cool design! Then, add another sheet of parchment paper on top, and flip it over again.
16. Carefully roll up the cake towards the design to make sure the picture is visible. Leave it to cool this way.
17. For the filling: Mix 1 cup heavy whipping cream on high until firm peaks are about to form. Add 1-2 tbsp powdered sugar (or even more depending on how sweet you like it!) and 1 tsp vanilla extract, and mix until firm peaks form.
- Trainer Tip: Feel free to get any type of filling you want for this cake! If you'd prefer a cream cheese frosting, buttercream, something with chocolate, or anything else, I'm sure those would taste great too!
18. Prepare your fruit by cutting into small pieces if necessary.
19. Unroll the cooled cake and remove all parchment paper.
20. Spread whipped cream into cake, add fresh fruit, then roll up the cake.
Done!
