Luscious Lemon Cupcakes ≠ Food

Celebrate the sunshine with these cute lemon cupcake soaps. These soaps feature Lemon Cake Fragrance Oil, on sale for the month of March. It smells wonderful in cold process and melt & pour soap. It will discolor to dark brown in cold process and tan in melt and pour. This recipe uses Vanilla Color Stabilizer in this recipe to keep the cakes yellow (as opposed to brown), but be aware that the stabilizer does not work as reliably in cold process soap.

This tutorial also features the Foaming Bath Whip, which stiffens to mimic sugary sweet frosting. These cupcakes are a real treat!

What You’ll Need:

24 oz White Melt & Pour Soap Base 
1 oz Clear Melt & Pour Base
1 teaspoon Fizzy Lemonade Pigment
2.5 tablespoon Liquid Glycerin
1.5 cups pound Foaming Bath Whip
6 tablespoons Meringue Powder
0.7 oz Lemon Cake Fragrance Oil
0.7 oz Vanilla Color Stabilizer
Silicone Cupcake Mold
Citrus Wax Tart Mold
Frosting Bag
1 M Frosting Tip
Soap Injector Tool
Square Silicone Spoon

ONE: Cut up 1 oz. clear melt and pour and place in microwaveable bowl. Heat in 15 second bursts until melted.

TWO: In a small container, mix 1 tbsp. Liquid Glycerin with 1 tsp. Fizzy Lemonade. Put 10 drops of this color mixture into the melted, clear soap.

THREE: Using a soap injector tool, squirt enough soap to just cover the first shoulder in the citrus wax tart mold. Fill 6 cavities, and spritz with alcohol. Allow to harden. If you’re in a hurry, 15 minutes in the freezer will do the trick quickly.

FOUR: Cut 24 oz. white melt and pour and melt in microwave in 30 second bursts.

FIVE: Once melted, add 1 tsp. of the yellow colorant mixture and blend well. Add 0.7 oz Lemon Cake Fragrance Oil and 0.7 oz. Vanilla Color Stabilizer. Add to soap and mix well.

SIX: Pour soap into the cupcake mold. Set aside.

SEVEN: In a large bowl, combine 1.5 cups Foaming Bath Whip, 6 Tablespoons Meringue Powder and 1.5 tbsp Liquid Glycerin. Whip mixture with a hand mixer. Continue whipping until stiff peaks form.

EIGHT: Put frosting tip inside frosting bag. Carefully spoon whipped frosting into frosting bag.

NINE: Pipe frosting onto the set up cupcake bottoms.

TEN: Get the citrus mold. If the soap isn’t popping out easily, put the soap in the freezer for 15 minutes to help with the mold release. Place little citrus slices in soft frosting tops.

Set aside for 48 hours and unmold! These soaps are ready to use, give away or sell right away. The frosting top will harden upon standing so if you are packaging these, wait for a few weeks until the frosting top is table enough to withstand some pressure.

    Hi, is it possible to make the melt and pour cupcake so it can be shrilled in the cup – with the curl on top – no frosting needed – just decorate the top? I received one of these as a gift and wold love to make one. What do you think? Thanks you always have great projects and advice.

    I didn’t read the reviews before soaping with this. I received a free sample. I used it in a white base. It’s been a week since unmolding and no discoloration. It actually only made my soap yellow upon initial pour but once I added color it was fine.

      Hi Amy!

      We have found that because of the vanilla content, that the Lemon Cake Fragrance Oil does discolor eventually unless Vanilla Color Stabilizer is used with it. If you get photos of your project, we would love to see them on our Facebook page! :)

    Sorry, one more question. Is there a way to get the frosting to harden without meringue powder? I want to do this project with my kids but my daughter is allergic to eggs. We’re going to order Brambleberry MP soaps to make gifts for other kids. Thanks!

      Hi Annie!

      There isn’t a good meringue powder substitute that I know of, but there are recipes that don’t include it. You will trade off a bit in hardness (this recipe does not harden) and pipe-ability though. I hope this helps! :)

      Ingredients: 1 Cup Foaming Bath Whip and 6 ml Fragrance Oil

      Directions: Whip the ingredients together in the mixer until it’s light, fluffy and forms peaks. Frost your soapy cupcakes!

    Hello! wow these look great, I was wondering, does the bath whip frosting turn hard? I’ve never used it before so I don’t know if you will be able to gift wrap these.
    Thanks :)

      Hi Diana!

      While the bath whip frosting does not get rock hard, it does firm up enough to gently package them. They will always need to be handled with care :). I would recommend placing them in a cupcake box, with some crinkle paper on the bottom so they don’t move around and touch the sides of the box :)

    Hi there! What a yummy soap! How hard should the cupcake bottom be before piping on the whipped soap? I’ve never used foaming bath whip before — will they unmold to be completely hard? Thanks!

      Hi Annie!

      That’s one of the great things about melt and pour…it hardens fairly quickly! I would recommend letting them harden while you make the “frosting.” The top should have formed a skin at this point, and it’s safe to gently pipe the frosting. Of course if you’d like to be on the safe side, you could give them another 20-30 minutes…or wait until they are completely hard! Up to you :)

      The foaming bath whip mixture will never become rock hard. But it will become hard enough to package, but will always need to be handled with care :)
