Take a 1 strawberry and cut off its stem. Put it into a round ice mold.
Pour mixture into the ice mold so that it is not overflowing (fill about half way).
Put the lid on top of your mold and let it chill for at least 15 minutes.
Carefully remove your cake from the mold. Pour syrup (I used maple) on your cake.
