Blueberry Jam Cupcakes

Final Blueberry Pic

For the final blog of fruit month, we went big with soap cupcakes! That’s right- while these treats look good enough to eat, they are in fact soap. We used Blueberry Jam fragrance oil to scent these fruit-inspired cupcakes and make them smell as delicious as they look. Be careful to warn those in your life with sweet-tooths!

If you’ve never made Cold Process soap before, stop here! I highly recommend checking out Brambleberry’s FREE four part series on Cold Process Soapmaking, especially the episode on lye safety. And if you’d rather do some reading, Bramble Berry carries a wide range of books on the topic, including Anne-Marie’s newest book, Pure Soapmaking. You can also checkout the digital downloads for that instant gratification factor.

Melt & Pour Instructions:

Weigh out 45oz clear melt and pour. Melt in microwave on 60 second bursts.


Add 12mL Blueberry Jam fragrance oil.


Add 12 drops of liquid white and 12 drops of liquid blue.


Pour soap into the cupcake molds and spray with rubbing alcohol.


Pour soap into a small 9 ball silicone mold. Be careful, they fill up very quickly! Spray with rubbing alcohol. Allow to harden at room temperature or pop in the freezer to quicken the process.


Once the soap has hardened pop out of the mold.



In a small ramekin or dixie cup, measure out 1/2 tsp of titanium dioxide in 1 tbsp of any fixed oil. We chose sweet almond oil. Mix well with Bramble Berry’s mini mixer. Repeat with blue.

Weigh out .5 oz of Blueberry Jam fragrance oil. Set aside.


Make sure you have gloves, goggles and long sleeves on before beginning to process the lye. Measure the distilled water into one glass container, and the lye into another. Carefully add the lye to the water and gently stir with a stainless steel whisk until solution is clear. Allow the lye to cool to around 60 degrees Fahrenheit by either labeling and setting aside, or by placing into a designated freezer. We recommend using Brambleberry’s Infrared Thermometer. These are amazing because they are so easy to use and you don’t have to worry about getting your thermometer covered in lye water!

While the lye is cooling, weigh out all the fixed oils in a large glass Pyrex bowl and heat in the microwave just until the kokum butter has melted.

For this technique we want our lye and our oils significantly cooler than usual. We want our lye to be around 60 degrees Fahrenheit, and our lye around 70 degrees before combining.

Frosting Instructions:

Whip the oils into a soft consistency using a hand mixer. They should be opaque before combining with lye.


Slowly pour a small amount of the lye into the whipped oils, and use a spoon to incorporate. Be careful not to splash any of the lye water. This soapmaking process is a lot more laid back that normal cold process, so you have much more time to work with your soap. Take your time adding the lye!


Once the lye has been incorporated into the oils (this can take a few minutes), turn the hand mixer or stand mixer on low. Scrape any batter that has splattered on the side of the container and then turn the mixer to a medium setting. Continue to whip for several minutes.

Once the lye and oils are completely combined, add the Blueberry Jam fragrance oil. Incorporate the fragrance oil with a spoon or spatula first until mixed, then turn the mixer on low and whip the ingredients together until completely combined. pic13
Continue mixing until you have achieved a frosting-like consistency. A good test is to lift the mixer out of the soap and if it keeps a peak, it is ready. This process can take between 20 and 30 minutes. Sometimes the soap will actually increase in temperature because of the lye reaction, so testing the temperature regularly and popping the mixture into the freezer for a few minutes can help this process.

Once the soap has reached the frosting-like consistency, split the frosting in half and add the titanium dioxide to half and the ultramarine blue to the other. Mix the color in well with a spatula or whisk. You can also give it a quick mix with the hand mixer.


Cut off about a half inch from the tip of the frosting bag and push the tip through. Scoop two frosting colors into opposite sides of the bag until full. You will have some frosting left over, and will need to fill the bag again during the frosting process.


Squeeze of some of the frosting until both colors come out, and to burp any air pockets that may be in the bag. Squeeze a dollop of frosting onto the middle of the cupcake bottoms.

Pipe the frosting around the dollop of frosting in a circular motion until you have reached a peak.



Sprinkle with glitter and place a small ball on top.


This recipe yields anywhere from 10-13 cupcakes, depending on how tall you make your frosting. We were able to make 11.


Let soap cure for 4-6 weeks before use. Enjoy your soapy cupcake treats!
