Easy-To-Follow Steps
- Add Your Decorations:
- Right before you dig in, press cotton candy along the side and top then scatter sprinkles. Add the cotton candy at the end so it doesn't dissolve.
- Put It All Together and Frost:
- Stack the first layer on your plate, spread on some frosting, and repeat for the rest. Get the sides and top covered for a smooth, even look.
- Mix Up the Frosting:
- Beat butter until it’s nice and soft, then slowly work in sifted powdered sugar. Alternate with a bit of cream or milk. Once it’s fluffy, mix in those extracts and coloring if you want more pop.
- Let the Cakes Chill:
- Let your cakes rest in the pans for ten minutes, then flip them out to finish cooling on a rack. Make sure they’re all the way cool before you frost so nothing melts.
- Pop Them In the Oven:
- Spoon the colored batters into your pans, smooth the tops, and bake about twenty-five to thirty minutes until a toothpick comes out clean. Level pans mean even layers!
- Tint the Batter Fun Colors:
- Split your batter into bowls—however many colors you like. Add in food coloring and gently mix so you get bold, even colors without overmixing.
- Alternate Wet and Dry:
- Work in your flour blend and milk, a bit at a time, starting and ending with the flour. Stir easy so the batter stays light.
- Blend in Eggs and Flavors:
- Add eggs one at a time, mixing in each so it’s nice and smooth. Then add both extracts so the taste spreads evenly.
- Make the Butter and Sugar Fluffy:
- With a mixer, beat softened butter and sugar in a big bowl for 2–3 minutes until it’s airy and very pale. That makes for a soft, delicate cake
- Dry Mix Next:
- Whisk together your flour, baking powder, and salt in a medium bowl so the cake rises even and clumpy spots are gone.
- Set Up Your Pans First:
- Start by getting your oven up to 175 Celsius. Grease three 20cm round pans and line each with parchment circles. This makes sure the cakes slide out cleanly without fuss.

The best bit? Mixing swirls of color in the batter with my niece and peeking into the oven to see our swirl art bake up. Plus, sneaky spoonfuls of frosting turned decorating into an extra sweet moment for us both.
How to Store
Stash leftovers in an airtight tub at room temp for a couple of days to keep them soft. Only add the cotton candy topping when you’re about to serve so it stays fluffy. For longer storage, chill it in the fridge but always let slices warm up first so every bite is still moist and soft.
Ingredient Swaps
If you can’t get cotton candy extract, almond or raspberry extract works for a fun twist. Gel food colors bring the brightest shades without making the batter watery, but regular food color will do in a pinch. Swap in non dairy milk for whole milk if needed—just expect the cake to turn out a tad less rich.
How to Serve
Bring this out for birthdays, spring showers, tea parties, or any day you want a wow moment. For full fairground magic, perch a tuft of fresh cotton candy on each slice. Pair it with berry punch or a fizzy lemonade for a cheerful treat tray.
