Key Ingredients for 18th Birthday Cake:
- For the Chocolate Layers:
- 330 g dark chocolate couverture
- 270 g butter
- 6 eggs (size M)
- 375 g sugar
- 3 tsp vanilla extract
- 280 g wheat flour (Type 405)
- 120 g starch
- 135 g baking cocoa
- 3 tsp baking powder (leveled)
- 1 tsp baking soda (leveled)
- 3 tsp apple cider vinegar
- 300 ml buttermilk
- For the Buttercream:
- 180 g sugar
- 50 ml water
- 3 egg whites (size M)
- 300 g soft butter
- For Decoration:
- 200 g dark chocolate couverture
- 50 g cream
- 30 g butter
- 200 g assorted cookies and sweets (like Amicelli, Lindor balls, Mikado sticks)
- 1 cake figure (18)
Step-by-Step Instructions:
- Preheat and Prepare:
Preheat your oven to 180°C (fan oven: 160°C). Grab three springform pans (Ø 20 cm), grease them with butter, and dust with a light sprinkle of flour to prevent sticking. - Melt the Chocolate:
Finely chop the dark chocolate and combine it with the butter in a metal bowl. Melt them together over a gentle simmering water bath, stirring occasionally until smooth. - Whisk Eggs and Sugar:
In a large mixing bowl, beat the eggs, sugar, and vanilla extract until the mixture is fluffy and creamy—this will ensure a light cake. - Combine Chocolate and Eggs:
Slowly pour the melted chocolate mixture into the egg mixture and mix thoroughly until well combined. - Sift Dry Ingredients:
In a separate bowl, mix together the flour, starch, cocoa, and baking powder. Sift this dry mixture into your chocolate-egg blend, gently folding it to keep the mixture airy. - Activate Baking Soda:
In a small bowl, combine the baking soda and apple cider vinegar until it bubbles—this will add lift to your cake. Gently incorporate this into the batter. - Add Buttermilk:
Stir in buttermilk which will add moisture to your cake’s crumb, ensuring a delightful texture. - Bake:
Divide the batter evenly among the three prepared springform pans. Bake in the preheated oven for about 35 minutes, or until a toothpick inserted into the center comes out clean. - Cool and Prepare Buttercream:
While the cakes cool, prepare the buttercream. In a saucepan, combine sugar and water, bringing it to a boil. Beat egg whites until soft peaks form, then gradually add the hot sugar syrup, beating until glossy. Lastly, add in the softened butter and mix until smooth. - Assembly:
Once the cakes are cooled, spread buttercream between the layers and cover the entire cake with more buttercream. - Decorate:
For the final touch, prepare a chocolate ganache by melting dark chocolate with cream and butter. Pour over the top and let it drip down the sides. Decorate with assorted cookies and sweets, and top with the cake figure!
What to Serve 18th Birthday Cake With
This 18th Birthday Cake pairs beautifully with a delightful scoop of vanilla ice cream or a dollop of whipped cream, providing a lovely contrast to the rich chocolate flavors. For drinks, consider serving sparkling lemonade or a festive punch to keep the celebration lively. Want to add more variety? Fresh berries or fruit salad make a refreshing side that complements the richness of the cake!
Top Tips for Perfecting 18th Birthday Cake
To ensure your cake turns out perfectly, keep these handy tips in mind:
- Don’t overmix your batter; this will keep it light and fluffy.
- If you want a less sweet cake, consider reducing the sugar slightly in the buttercream.
- Always let your layers cool completely before frosting to avoid melting the buttercream.
Storing and Reheating Tips
If you have leftover cake (though we doubt it!), store it in an airtight container at room temperature for up to 3 days. For longer storage, wrap it in plastic wrap and refrigerate for up to a week or freeze for up to a month. When ready to enjoy again, simply thaw it in the fridge overnight and serve at room temperature for the best taste!
There you have it, a recipe to create an unforgettable 18th Birthday Cake that will surprise and delight everyone at the party! Happy baking and celebrating!
