Ingredients & Supplies

Yields: 4–6 small bars depending on your mold size

• 1 lb goat milk melt and pour soap base (or shea butter base) 
• 1 tsp pumpkin pie spice (yes, the real baking blend!) 
• ½ tsp ground cinnamon (optional for visual specks) 
• 1 tsp vitamin E oil or sweet almond oil 
• 1–2 tsp brown mica or orange soap-safe colorant 
• 1 tsp vanilla extract (optional for scent depth—make sure it’s oil-based or use a fragrance oil blend) 
• Pumpkin pie fragrance oil (skin-safe, approx. 1–2 tsp per pound of soap base) 
• Rubbing alcohol in a spray bottle 
• Silicone soap mold (round, square, or pie-slice shaped) 
• Microwave-safe jug or double boiler 
• Stirring sticks or silicone spatula 

Step-by-Step Instructions

1. Chop and Melt the Soap Base

Cut your melt and pour soap base into small cubes and place in a microwave-safe jug. Microwave in 30-second bursts, stirring between each round until fully melted. (Do not let it boil!)

2. Add Scent and Spice

Once melted, stir in your fragrance oil, pumpkin pie spice, and optional vanilla extract. Add a pinch of cinnamon if you like the flecked look.

Tip: Spray your mold lightly with rubbing alcohol before pouring to prevent bubbles.

3. Colour and Pour

Add your mica powder or orange colorant, a little at a time, until you reach your ideal pumpkiny hue. Stir well, then carefully pour the mixture into your soap molds.

Immediately spritz the tops with rubbing alcohol to remove surface bubbles.

4. Let It Set

Leave the soap undisturbed at room temperature for 2–4 hours until fully hardened. Pop the bars out of the mold once they’re firm to the touch.

Optional: If you’re feeling fancy, melt a small amount of white soap base and pipe a “whipped cream” swirl on top using a piping bag and star tip.

Tips & Variations

• Make it two-tone: Pour half your batch in orange, then top with a creamy vanilla layer for a pie-slice look. 
• Add oatmeal: Toss in 1 tsp of ground oats for a gentle exfoliant and rustic charm. 
• Use pie molds: Silicone molds shaped like pie slices or tart pans give these a dessert-style finish. 
• Gift-ready idea: Wrap in wax paper, tie with twine, and add a “Pumpkin Pie Soap” tag for instant fall gifts. 

How to Store Homemade Soap

Keep your finished soaps in an airtight container or shrink wrap them if you’re gifting. Melt and pour soap can sweat in humid climates, so cool, dry storage is best.

This DIY pumpkin spice soap recipe is everything you want from a cozy fall project—easy, fragrant, and irresistibly cute. Whether you’re new to soap making or a seasoned maker prepping for a market table, these little bars will have everyone asking, “Where’s the whipped cream?”
