Notes

Oats: I used 100g rolled oats and 25g of jumbo oats for extra bite and texture. It’s fine to use all rolled oats, don’t buy jumbo if you haven’t got them. You could use ALL jumbo but the cookies will be drier and more crumbly
Portioning: To make sure that your cookies are even sizing, you could  use an ice cream scoop. It’s my favourite cookie, cupcake and muffin baking trick and kids LOVE using a scoop too
Leave space: Leave plenty of space between your cookies on the baking tray. Use 2 baking trays if you need to
Line the tray: Use baking paper (not greaseproof paper) to line your baking tray
Storing: These will keep in an airtight container for up to about a week
Freezing: You can freeze the dough ahead of time and bake on the day you need them. The dough will keep for around a month in the freezer. You can also freeze the cookies in a freezer bag too. Defrost ahead of wanting to eat them
Variations of Oat Cookies:
  • Chocolate Chip Oatmeal Cookies – Replace the raisins with chocolate chips
  • Breakfast Oatmeal Cookies – Add a very ripe, peeled and mashed banana to the recipe with the egg
  • Peanut Butter Oatmeal Cookies – Omit the raisins and add 75g of chunky peanut butter
