Overnight oatmeal cookies

Scorrere verso il basso

These butter-free overnight oatmeal cookies are some of the simplest cookies I’ve ever made. Just throw all the ingredients into the bowl, mix, place the bowl in the fridge for several hours and then with a spoon make portions for each cookie and bake. Easy peasy. They are perfect for those who are not experienced with homemade baked goods. They are also perfect for both breakfast and snack as they are rich in flavor but not too sweet. These are semi-soft cookies with crunchy edges. They are prepared with lots of rolled oats, almonds, chocolate chips, raisins, chia seeds (optional) and olive oil. You can customize them by adding different types of nuts, different types of chocolate or adding spices such as cinnamon.

Baking time

  • Line a baking sheet with baking paper. Using a spoon divide the batter in equal portions. From these ingredients I created 18 cookies using about 1 tablespoon of batter for each cookie. Remember that they spread a lot during baking.
  • Bake your cookies for 15 minutes in a static oven preheated to 180 ° C. Once taken out of the oven, wait a few minutes and then let them cool completely on a cookie rack.
