Rainbow Ice Cream Sandwich

If you’re reading this blog post you probably know that I’m obsessed with Rainbows. If you didn’t know that I’m obsessed with rainbows, then I should probably introduce myself! Hi! I’m Elise and I’m obsessed with rainbows! Now that we’re all friends here, I’m so excited to share with you my Rainbow Ice Cream Sandwich recipe. These are perfect for warm summer days and rainbow fanatics everywhere. If you’re obsessed with Rainbows check out my Rainbow Layer Cupcakes and my Unicorn Pinata Cookies.

For this recipe, you’re going to be working with my delicious cookie dough coloured in all the colours of the rainbow. You can find that recipe here. I strongly recommend using high quality ice cream for this recipe. While I’m usually all about a bargain, but you really need high quality ice cream. Low quality ice cream just doesn’t refreeze well. It gets super icey, and we don’t want icey ice cream! Trust me, get the high quality. You won’t regret it.


  1. Spoon vanilla ice cream into a shallow baking tray (without parchment paper). Use a spatula to smooth out the top so that it’s as flat as possible.
  2. Transfer to the freezer for 6-12 hours.
  3. Roll out your cookie dough so that it’s skinnier at one end, and wider at the other. This should be like an elephant trunk.
  4. Cut the dough off into even pieces.
  5. Place a few drops of different food colour paste onto each piece of cookie dough. Massage the colour through. The smallest color should be purple, the next larger should be blue, then green, then yellow, then orange, and the largest should be red.


  6. Shape each cookie dough into a flat rectangles. Then, wrap them each individually in plastic wrap (except for the purple!). Transfer cookie dough wrap pieces into the fridge.
  7. Roll your purple cookie dough piece so that it’s the shape of a long cylinder. Cut the edges so that they’re nice and clean.
  8. Transfer to the freezer for 20 minutes.
  9. Once your purple piece is frozen, take it out of the fridge. Then, sprinkle flour onto your bench and roll out your blue cookie dough so that it’s 3-4mm thin. Take your purple cookie dough and place it right on top. Trim the sides of the blue if needed. Then, roll the blue douh entirely around the purple. Place back on the tray and freeze for 15-20 minutes.
  10. Repeat the previous 2 steps with green, then yellow, then orange, and finally red.


  11. Freeze for 2 hours.
  12. Once set, remove from freezer. Then, preheat a moderate oven (175C/350F)
  13. Cut of the uneven edges and discard. Then, cut your log so that they’re 3mm thick. Place each cookie piece on a baking sheet lined with parchment paper, and bake for 8-10 minutes.


  14. Remove from oven and allow cookies to completely cool.
  15. Remove ice cream from the freezer. Then, use a cookie cutter that’s the same size as the rainbow cookie you’re working with. Press the cookie cutter down into the ice cream, then twist, and pull it out. Then, press the ice cream down onto one rainbow cookie. Place another rainbow cookie on top.


  16. Do this with the rest of your cookies!

What You’ll Need:

  • Plain flour
  • Good quality vanilla ice cream – the higher quality, the better your softened ice cream tray will re-freeze
  • 1 batch of vanilla sugar cookie dough
  • Rainbow colours – I used americolour paste colours
