I bought a new Silikomart mold from Amazon in March and made a mousse log for hubby’s birthday. The base unit of this mold is of hard plastic and two silicon mat inserts, one smooth and one textured, are included. The 3D effect of the stars was absolutely stunning and I really loved it. Honestly speaking, these molds aren’t quite affordable (at least for me) and I have been waiting for so long for a price reduction in order to buy one. I wish the company would consider selling other mats separately so I could make more styles..
This cake consists of chocolate mousse, strawberry mousse and two layers almond sponge cake. The almond sponge cake is a slight adaptation from my Opera Cake and oil is used instead of butter for more moisture. Another ingredient that goes well with chocolate mousse is raspberry. Check out my other recipe, Raspberry and Dark Chocolate Mousse Cake, for more details. Sometimes I’m too lazy to make more than one mousse favor, if that’s the case then the cake could be assembled with only one single step without freezing the cake before filling with another layer. One thing to pay attention is that in order to successfully unmold the cake, the cake must be completely frozen. And it takes at least 6 hours for the frozen cake to defrost in the fridge so make sure to plan ahead.
以下是三月中做給老公的生日蛋糕，內裏有朱古力慕絲、士多啤梨慕絲和兩片杏仁海綿蛋糕。 杏仁海綿蛋糕配方修改自歌劇院蛋糕，EC用了液體油取代無鹽牛油增加蛋糕濕潤度。 除了士多啤梨之外，紅桑子跟朱古力慕絲的味道也很夾，詳細食譜可參考紅桑子黑朱古力慕絲蛋糕。 有時EC也很懶不想花時間做兩種不同口味的慕絲。若只做一款口味的話便可一次過組合蛋糕，省卻了在中途把蛋糕放進冰箱內冷凍後才做第二層的步驟。 值得注意的是，蛋糕必須完全冷凍至冰硬後才可完美脫模，之後存放在雪櫃中至少六小時才能完全退冰。因此，製作這類蛋糕時必須預先計算好食用時間。

Pour mixture into a parchment paper lined 11” square cake pan then smooth top. Bake in a 350°F/175°C preheated oven for 15 to 18 minutes or until the cake springs back to the touch. Remove from the oven and transfer the cake to a wire rack to cool completely. Trim cake into rectangles according to the size of the mold. Keep frozen until ready to use.
