This recipe uses jelly crystals, or jello, as a colouring and flavouring so pick any flavour you'd like! (Omitting the crystals still works though it isn't as tasty)
Just to clarify, for Americans this is Jello crystals not jam/jelly :) (packet should be around 75g)
I decided on blue heaven because BLUE COOKIES!! Need I say more ;)
Soften your butter or just chop it up small
Measure out powdered sugar
Cream the softened butter
Add egg yolks, one after another while beating
Combine until well mixed
Noooww we add the jelly crystals and watch it turn colour
:D I feel like a little kid
If it's not exactly the colour you'd like it to be, a little bit of food colour won't hurt
After your dough is done, slap the lot onto some grease proof paper and push into a round log shape, pushing the dough to eliminate any air bubbles. Tightly roll up the paper.
Cut a cardboard roll in half to ensure your log stay round! (I used both halves; one near each end)
Fold over the ends so the dough doesn't dry out :) then place into the fridge at least for 30 min until firm before baking (can store in the freezer too; do not thaw before baking)
When ready to bake, slice chilled dough into slices; you can make them as thin or as thick as you'd like! (Just not toooooo thick yknow)
Lay on baking paper
Bake in a preheated oven for about 12 min, but it depends on your cookie thickness
Don't let them brown too much or you won't be able to see the bright colours of the jelly!
Cool, then store in an airtight container for up to 2 weeks (you can freeze baked cookies too)
You could also roll the log in sprinkles for real pretty cookies!
What a beauty!
Icecream sandwich, anyone? (Making slightly thicker cookies and baking for a bit longer is advisable) (triple toffee ice cream is heavenly with these just sayin')
