Makes 2 cakes
2/3 cup spring water
1 pinch of vanilla sugar
~1/8 teaspoon agar powder (you may need to experiment a bit to attain desired texture)
1. Measure out the water in a microwaveable measuring cup and add the sugar. Microwave for 30 seconds and stir until sugar is dissolved.
2. While stirring, sprinkle on the agar powder. Microwave again for 30 seconds and stir for a minute. Continue microwave and stirring as needed until the agar is all dissolved, although you’ll probably still see clear bits floating around in the water.
3. Carefully pour into your desired molds; pop any bubbles that may appear. Transfer the molds to the refrigerator and allow to set for several hours or overnight.
4. Carefully unmold the cakes and serve immediately with your desired toppings.
