Set up your equipment on a clean counter.
Cut the soap base into small cubes.
This helps it melt faster and evenly.
Prepare your mold by placing it nearby.
Put soap cubes in your microwave-safe bowl.
Heat for 30 seconds at a time.
Stir between each heating interval.
Continue until completely melted and smooth.
Stir in ground coffee, coffee extract, and coconut oil.
Mix well to distribute everything evenly.
Add fragrance oil if you're using it.
The mixture should smell wonderful now.
Carefully pour the mixture into your soap molds.
Work quickly before it starts hardening.
Tap the mold gently to remove air bubbles.
Allow soap to cool at room temperature.
This takes about 2-3 hours.
Don't rush by putting it in the fridge.
Pop out once completely hardened.
