1. Prepare ingredients, chocolate.

2. Steam over water to melt the chocolate.

3. Put it into a piping bag and cut a small opening.

4. Squeeze it on the mold. What I made is two-color chocolate Happy Birthday. First, squeeze the dark chocolate liquid into the font.

5. There will be excess chocolate during the squeezing process. Wipe it clean with a napkin to make the font clearer.

6. Then freeze in the refrigerator for 2 hours. The above are the steps to make a birthday number card.
