These are my cookies go-to when I need something fun, bright and colourful! These slice n' bake rainbow cookies are not only so pretty, but easy to make too. With pride month coming to an end I thought I had to contribute at least one bright and colourful rainbow dessert to show my support are raise awareness!
Customising your rainbow pattern
The thing with these cookies is that they will be unique to anyone that makes them! There is no right or wrong when it comes to putting together the rainbow pattern, and the fun comes from just going with the flow.
To create the pattern I did with these cookies, I simply rolled each colour out into a long log, pressed them together and shaped it into an even log.
To create a more patchy colourful effect you can tear the colours into small chunks and place them randomly on a sheet of cling wrap. Then roll the sheet of cling wrap up into a log, ready to be sliced and baked.
If you are feeling adventurous and would like to recreate a rainbow, roll each colour out into a long strip except for purple. Roll purple into a long, thin log. Then wrap each colour around the purple log in the reverse order of the rainbow. Freeze the log, then cut in half lengthwise before cutting into small rainbow semicircles.
Make these cookies an expression of you!


Tips on creating the perfect slice n' bake cookie
Slice n' bake cookies are one of the easiest kind of cookie to make because you don't need to shape each cookie individually. Just roll the dough into a log and bake! Here are a couple of tips to help the easy process go even smoother!
- Roll the dough into an even log
Making sure that the log is an even diameter the whole way through will ensure that you don't get different sized cookies after they have been sliced.
- Give your log a second roll after it has been chilled in the fridge
Because the dough will be soft after the initial roll, when it rests in the fridge it won't maintain its perfectly round shape. Instead it will have a flat edge. Make sure to roll this out after it has been refrigerated to even it out!
- Slice quickly
The longer the dough sits out, the more the dough will soften up. The more the dough softens up, the harder it will be to slice nice even cookies without the dough getting squished beneath your knife. Work fast and precise!
- (OPTIONAL) If you want perfectly round cookies
I have a bit of cookie perfectionism going on. I hate it when my cookies are even the tiniest bit lopsided. If you are like me and want that perfect shape; the moment the cookies come out of the oven get a cookie cutter that is just smaller than the diameter of your cookies and cut them out. You have to do this while they are hot otherwise the cookies will crumble and break!
If you don't mind your cookies having a little character then feel free to skip this step!
