Expert Tips for Perfect No Bake Cookies

  • Stick with quick oats, they give the cookies the best texture. Old-fashioned oats can make them fall apart.
  • Be careful not to overboil the mixture! If it cooks too long, the cookies can turn out dry and crumbly.
  • Let them cool completely before moving or stacking, or they might lose their shape.
  • Want bite-sized treats? Use a spoon or small cookie scoop to drop teaspoonfuls of the cookie dough. It makes portioning super easy and perfect for snacking!
  • In a hurry? Pop them in the fridge for 10–15 minutes to help them set faster.

Frequently asked questions – FAQ

Storage Tips For Your No-Bake Cookies

  • Room temp: Keep them in an airtight container and they’ll stay fresh for up to 5 days at room temperature.
  • Fridge: They’ll last about a week in the fridge when stored in an airtight container, just let them sit out for a bit before serving so they’re not too firm.
  • Freezer: Want to stash some for later? Layer them with parchment paper in an airtight container and freeze for up to 3 months.

Can I use old-fashioned oats instead of quick oats?

They can work in a pinch, but the texture will be rougher and they may not hold together as well.

Why didn’t my cookies set?

You may not have boiled the mixture long enough. Make sure to let it reach a full rolling boil and time 1 full minute.
