Black Raspberry Vanilla Cream Swirl Cake

            This Black Raspberry Vanilla Cream is a one of our summer soaps that will make your mouth water. The light fragrance smells similar to the Raspberry Vanilla at Bath and Body Works, in my opinion, and the oil combination in this recipe are light and not too moisturizing so it leaves a light clean feeling on your skin. I usually like to move away from olive oils and Shea butter during the summer months and use oils that are sturdy and cleansing. This is, of course, completely subjective, but my preferred way to design soap recipes.

This recipe includes 4 lbs of oils and will make 12 bars of soap in the shape of a cake slice.

What you need for this recipe:

  • Distilled Bottled Water
  • Lye (NaOH)
  • Castor Oil
  • Coconut Oil
  • Lard
  • Rice Bran Oil
  • Mica: Soapberry Purple (morphing)
  • Mica: Raspberry Shimmer Pop (Not Stable in CP) Will turn a berry peach
  • Titanium Dioxide
  • Vanilla Stabilizer

ONE – The first section of this recipe is 3 lbs. of soap. The remaining 1lb will be reserved for the berries and icing. Prepare your area and wear your safety gear: glasses, gloves, and mask. Gently pour the lye crystals into the container of cold distilled water. Stir until completely dissolved. Set this aside to cool to room temperature.

TWO – Combine the four oil blend and mix thoroughly.Set this aside and prepare the colorants. The colorants we have chosen for this projects are not your typical cold process choices. In the demonstration I have used: Soapberry Purple, Raspberry Shimmer Pop, and Titanium Dioxide. Soapberry purple is a morphing mica, and Raspberry Shimmer Pop is unstable in CP soap and will fade to a berry peach.

THREE – When the lye water solution is within 20 degrees of the temperature of the oils, pour the lye into the oils and blend with a stick blender. When this is thoroughly emulsified pour in the Black Raspberry Vanilla fragrance oil and the Vanilla stabilizer. Next, separate the soap into 3 bowls: 2 parts, 1 part, and 1 part. In the two parts bowl add the Titanium Dioxide and color it cream/white. In the other two bowls add the other colorants.

FOUR – Pour the base of the cake first with the cream/white soap. Then pour the other two colors in a drop swirl, and give it a good mix with a skewer. Set this aside to firm up  while you prepare the next pound of soap for the berries and icing.

FIVE – Following the same instructions above make the same recipe with the oils reduced to one pound. Add the fragrance oil and vanilla stabilizer. Separate the colors in the same proportions as the first part. Fill each portion of soap into a piping bag. All three colors can use either a circle tip or a star tip. The white soap must use a larger tip than the other two colors.

SIX – The next portion will be piped on to the top of the cake. Wait until the soap firms to piping consistency. This is where it is soft enough to easily move through the bag and firm enough to hold its shape when left behind. Begin by building a perimeter of soap around the edge of the cake with the white color soap. Pipe either a dollop or a star and continue to build upward until you run out of white soap. Next, cover the frosting with smaller balls or stars with both of the other colors building berries all over the top of the white icing.

SEVEN – Dust this with a layer of glitter and set it aside for 24 hours before it is ready to cut. Once it has been cut into 12 pieces, allow this soap to sit alone for 4 – 6 weeks before use.
