Mash the avocado well, so it becomes a purée. You can do this with a fork, masher or handheld immersion blender.
Add the oats and raisins to the bowl.optionally, you can add in a few dark chocolate chips if you want slightly sweeter cookies too. Then just won't be quite as healthy!
Mix it all together well. Get the kids involved in the mixing!
Roll the healthy cookies into balls and place onto a lined cookie sheet, then flatten slightly.
Bake for 20 minutes or until the edges begin to turn golden. Cool slightly then transfer to a wire rack to cool completely.
Be sure to cool the cookies before giving them to kids, as raisins can get very hot.
Tips: be sure to mash the avocado really well. If it's ripe, this should be easy.
For smaller kids, use finer quick cook oats so the pieces of it are smaller.
You could shape the avocado cookies into "fingers" for easy snacking, so little ones can hold them easier.
Variations: you can swap the avocado for mashed banana in these healthy cookies for kids.
Try adding in some extra flavors with a pinch of cinnamon or pumpkin pie spice blend.
