On a lightly floured surface, pour out the dough. Roll it out to about 1/4” thick. Cut out your cookies using cookie cutters. Move the cut cookie to a baking sheet on parchment paper. Once the tray is full, put it into the fridge to chill.
Roll out the rest of the dough until you are finished.
Preheat the oven to 350F.
Place the cold trays into the oven and bake for 10-12 minutes.
Remove them from the oven and allow them to cool on the tray for a couple of minutes before moving to a wire rack.
Once they are fully cooled, make the royal icing.
In a stand mixer bowl with a whisk, add in the meringue powder and warm water. Mix until foamy.

Next add in the icing sugar. Whip until fluffy.

If you have one batch of the same colour, I would dye it now. If not, separate it into bowls and dye each of them. If it is too thick, add a drop of water at a time. If it is too thin, add a little bit of icing sugar.

Put the royal icing into piping bags with the tips of your choice and begin decorating. Enjoy!
