Recipe Information
Ingredients
- 250 grams Butter
- 300 grams Granulated sugar
- 5 large Eggs
- 300 grams All-purpose flour
- 2 teaspoons Baking powder
- 120 milliliters Milk
- 1 teaspoon Vanilla extract
- 300 grams White chocolate
- 200 grams Sweetened condensed milk
- 12 grams Gelatin powder
- 60 milliliters Water (for gelatin)
- 150 milliliters Water (for glaze)
- 150 grams Glucose syrup or light corn syrup
- 4 as needed Gel food coloring (blue, purple, black, white)
Instructions
Preheat your oven to 175°C (350°F). Grease two 8-inch round cake pans and line them with parchment paper.
In a large bowl, cream together the butter and granulated sugar until light and fluffy using a mixer.
Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In another bowl, combine the all-purpose flour and baking powder. Gradually add the dry ingredients to the wet mixture, alternating with milk, starting and ending with the dry ingredients. Mix until just combined.
Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely.
Once cool, level the top of the cakes using a serrated knife if necessary. Layer and assemble the cakes with your choice of filling (buttercream or ganache works well). Chill the assembled cake in the refrigerator for at least 2 hours.
For the mirror glaze, first bloom the gelatin: sprinkle gelatin powder over 60 milliliters of water and let it sit for 5-10 minutes.
In a small saucepan, heat 150 milliliters of water, glucose syrup, and granulated sugar over medium heat until the sugar dissolves and the mixture comes to a gentle boil (around 103°C or 217°F). Remove from heat.
Stir in the sweetened condensed milk. Add the bloomed gelatin and stir until it is fully dissolved.
Pour the hot mixture over chopped white chocolate in a heatproof bowl. Let sit for 1-2 minutes, then blend using an immersion blender until smooth and shiny. Avoid incorporating air bubbles.
Divide the glaze into separate bowls and color with gel food coloring to create galaxy colors (e.g., blue, purple, black, and white). Stir each color gently.
Place your chilled cake on an inverted bowl or stand over a large baking sheet to catch drips. Pour the colored glazes over the cake, alternating colors and swirling them with a spatula to create a galaxy effect. Work quickly, as the glaze will begin to set as it cools.
Allow excess glaze to drip off, and use a clean knife to remove drips from the bottom edge of the cake. Let the glaze set for 10-15 minutes before transferring the cake to a serving plate.
Decorate with edible stars or glitter for an extra galactic touch. Serve and impress your guests!
