I love making shaped sugar cubes. They are super easy to make and add such a nice detail to a party or just make daily tea drinking extra special! These homemade shaped sugar cubes would also make a nice homemade gift.
Mix 1/2 cup sugar with 1 teaspoon water and tiny (pin drop) bit of paste food coloring. Mix well. It will feel like damp sand.
Carefully flip mold over and remove the hearts. It is a bit tricky during the flip but, I found it easiest to fill mold and immediately remove so I could keep making the sugar cubes. Wipe mold between fillings.
