Here’s another project that uses the Cada Twinkies mold! I can’t stress enough how easy this mold is to use. If you missed the pumpkin Twinkies, be sure to check them out here.

This is probably my favorite Halloween project that we knocked out for the blog this year. They are just so dang cute! I LOVE them!

For this project, Robyn and I used Robyn’s Humid Weather Bath Bomb Recipe. We were together making soap in Florida and it behaved perfectly with the high humidity here.

We made the eyes using the Sprinkle Recipe and the mummy wrapping using Wonder Bar.

This tutorial is all about the design! You can use any bath bomb recipe that you prefer. Let’s jump into it!

For the mold, we used a Cada Twinkies bath bomb mold. It couldn’t have been any easier to use. You simply overfill the mold with mix, pressing well, slice off any overfill, place onto a tray and bang with a spoon to release. So. Easy.

We filled the Twinkies with a fun Quick Glembed Powder Mix! It is a simply an embed powder. An embed powder is waaaaay quicker and waaaaay easier than making embeds. (Be sure to make it ahead of time so it’s ready to go!)

This Glembed Powder Mix is super sparkly because we used synthetic mica (fluorphlogopite mica). Synthetic mica is generally used when you want the pearlescent look to your bath water. Just note…you use a lot! We could have even used more fluorphlogopite in this recipe…so test test test! Here’s how we made our Glembed Mix.

Quick Glembed Powder Mix for Bath Bombs

  • Baking Soda – 50 grams
  • Citric Acid – 50 grams
  • Fluorphlogopite Mica – We used 1 tablespoon of Super Sparkles and 1 tablespoon of Imperial Purple from Nurture Soap
  • Water – 5 sprays from fine mist sprayer

Step 1: Add baking soda, citric acid and fluorphlogopite mica together in a bowl.

Step 2: Mix well and spray with water as a binder just so it firms up when molded into your bath bomb.

Set aside and get your bath bomb mix ready for your bath bombs.

We used Robyn’s Humid Weather Bath Bomb Recipe!

Step 1: Mix up your bath bomb mixture! We left it white since we’re making mummies!

Step 2: Add binder until your mixture is the perfect consistency for molding your bath bombs.

TIP: Water as a binder: We LOVE water as a binder. It activates the mixture a tiny bit and creates a bath bomb that dries really quickly! You don’t need much! Be sure to mix it well to avoid warting.

Step 3: Mold your bath bombs! Start by filling the Twinkie mold about 1/2 full of white bath bomb mix. Press it down and make a divot down the middle, pressing the mixture up the sides of the mold.

Step 4: Fill the divot with Glembed mix. Make sure you have white mixture all the way up the sides of the mold and that the embed mix is just down the middle of the mold. You don’t want it showing through when your bath bomb is unmolded.

Step 5: Cover with more white mix and press hard.

Step 6: Overfill, pressing hard. Slice off the overfill using a knife.

Step 7: Place your mold on a flat surface; we used a tray.

Step 8: Tap the mold with a spoon or something similar. Lift the mold up off of your bath bomb. If your bath bomb is still stuck a bit, tap with spoon while lifting to help release.

Step 9: Dry your bath bombs before decorating. Depending on how humid it is where you live, you might need to dry them 1-4 days. I dry in a room with a dehumidifer running and mine only need about 24 hours to dry (even in humid Florida!).

TIP: Drying your bath bombs: The best way to quickly dry your bath bombs is to place them in a room with a dehumidifier running. If you have no humidity where you live, then you probably don’t have to do this. But if you have any humidity, I highly recommend investing in a dehumidifier. Even if you don’t have high humidity, it can help your bath bombs dry quickly so you can decorate and package even faster! I like this dehumidifier from Homelabs on Amazon.

Once dry, you can decorate!

These adorable eyes are made using the Sprinkles recipe! We made them ahead of time.

You’ll also need some Wonder Bar to pipe onto the mummy bombs! You don’t have to make a whole batch, because then you’d have to much left over. You can simply grab some from a masterbatch. Check out this blog post where we talk about how to masterbatch Wonder Bar.

Step 1: Pipe a dab of Wonder Bar onto your mummy and place your eyeballs.

TIP: When piping onto bath bombs, be sure to spray with 91% alcohol first. It helps the piping stick!

Step 2: Pipe bandages onto your mummies using a small basket weave piping tip. We didn’t really have a solid technique for this! LOL! Just try a few things and see what looks good. You can look up mummy cupcakes and cookies for some piping technique tips.

Step 3: Allow your mummies to dry!

Happy Making!

Making bath bombs in wet, rainy weather can be so frustrating! If you live in an area with constant high humidity, then you’ll need a recipe that can hang day in and day out without failing, warting, cracking or crumbling. Check out Robyn’s Humid Weather Bath Bomb Recipe!
