INGREDIENTS AND SUBSTITUTES
ingredient quantities please refer to the recipes card (Click here!)!
- Milk Chocolate – you could substitute dark chocolate you prefer. For this recipes I am using milk chocolate (to lower the cocoa to suit my little one), so if you using dark chocolate you may increase the amount of sugar by 10 – 20%.
- Vanilla Paste – you could skip this or substitute with an equal amount of vanilla extract.
- Unsalted Butter – I always purchase unsalted butter so that I can control the amount of salt for my baby and any other recipes. But if you only have salted butter, then you can omit the salt in this recipe.
- Sugar – Regular white castor sugar will do. If you prefer, you could substitute with brown sugar.
RECIPE TIPS
- Act QUICK. This recipes contains higher fats percentages, so it tends to “deflate” easily, so every steps have to act quicker than usual. Pre-weigh all the ingredients that you need. Move to next step once the Thermomix® is calling.
- Preheating the oven. Must have the oven ready. Once the cake batter is ready, pour into the cake mound and put it into the oven immediately.
- DO NOT open the oven during baking. Do not open the oven during the baking, it will cause the cake to deflate instantly. The cake will take at least 25 minutes cook, if you would like to check the doneness of the cake, check the cake browning through the oven window or simply smell it.
STORAGE
The cake can be kept in a dry place at a room temperature for up to 3 days. Or place the cake in the refrigerator for up to 7 days; wrap it well so it doesn’t absorb moist or other odours. The cake will also keep in the freezer for up to a month. Just thaw before using.
If you are baking ahead for a decorative cake, you will want to keep the naked cake cool until it can be decorated. Let cake cool completely; if you wrap it while it’s still warm, it will get moist inside the cake, which isn’t good for freshness and the texture. Once the cake is at room temperature, wrap it tightly with plastic wrap or a resealable bag. Make sure the cake is sealed on all sides.
