If you’re looking for a wonderful alternative to your standard cookie, then these funfetti cookies are incredible to make. They’re beautifully flavoured with rich vanilla bean paste and crammed with the most magical sprinkles for a colourful finish. Simply pop one of Epic Snax’s Giant Toastin’ Marshmallows on the underside of one cookie, toast in the oven until gooey and melted, and then squish another cookie on top. Notice how the marshmallow oozes out the sides, which in my opinion is totally irresistible. These cookies would be ideal for a celebration or party – they’re colourful and utterly delicious!

What do you need for these Funfetti Cookies?

  • Sugar. While you can use caster sugar for these cookies, I personally prefer granulated for a more gritty texture.
  • Eggs. Use large free-range eggs for this recipe. You can buy egg yolks in cartons for less food waste.
  • Butter. Always use unsalted butter so you can control the amount of salt that goes into your bake. A high-carotene butter will be creamier and more buttery – perfect for that ultimate flavour.
  • Vanilla. Since these cookies are plain and simple, using a high quality vanilla bean paste is a great way to add superb flavour. You can substitute vanilla essence or extract for the paste if that’s all you have.
  • Sprinkles. While you can easily find 100s and 1000s, or general sprinkles in the supermarket, I really love Sweetapolita’s range of interesting and unusual sprinkles.
  • Leaveners. You’ll need some bicarbonate of soda and cream of tartar for this recipe.
  • Epic Snax Giant Toastin’ Marshmallows. Bigger and better than any other marshmallows around, Epic Snax are perfect for that super gooey, pillowy mouthfeel.

Tips for making these Funfetti Cookies:

These funfetti cookies are seriously great and here’s exactly why I love them:

  1. Use a cookie scoop. Use a 50g cookie scoop for bigger cookies, or a 25g cookie scoop for smaller cookies, which will yield more. Using a scoop makes portioning them super easy.
  2. Choose your sprinkles wisely. Bigger sprinkles will show more obviously in your cookie dough. I like Sweetapolita’s for their range of beautiful sprinkle mixtures.
  3. Use good quality vanilla. Vanilla bean paste is best, simply for the richness of flavour.
  4. Rest your dough. This allows the fats to soak up the flour and produce a richer, more beautiful flavoured bake.
  5. Toast your marshmallows in the oven. I like using a blowtorch for toasting Epic Snax’s marshmallows, but baking them for 10 minutes on top of your cookies will allow them to puff up and get really gooey inside for the perfect smoosh.

  • 1 tbsp vanilla bean paste

  • Sift in the flour mixture and beat on a low speed until it begins to come together. Then add the sprinkles and beat until just combined and it starts to resemble a dough.
