In a large mixing bowl or a large glass container stir all your oatmeal base ingredients together well. Refrigerate your oats (covered so they don't dry out) for at least 6 hours to overnight.
Once they're ready, stir your oatmeal really well, this will make it creamier.
Using a fork, slightly mash the fresh raspberries.
Divide equally between 4 jars layering the oatmeal with mashed raspberries as shown in the photos.
Top with extra raspberries and serve!
Or keep refrigerated for up to 4 days.
Enjoy!
