I have a 2 shaped cookie cutter that I have never used before... And I want to make some cookies for Sunday... my sons Birthday party

What cookie recipes would you recommend, considering they will be shaped not chunky and round? Should I use a recipe like the one for christmas cookies? Just a basic one?
I was thinking of covering them in sprinkles anyway.....

Any recipe ideas or advice? I've NEVER made biscuits before

thanks ladies
