    Made this with peaches and blueberries, and it was amazing! Love the idea for using it as a breakfast meal prep too.

    I love oatmeal for breakfast, so I tried this today. It was easy, quick and would be great for a warm guest breakfast in the winter. I made two changes Almond Flour instead of Oat Flour, and I mixed unsweetened shredded coconut with 3 Tbsp of Demerara sugar. I thought it was awesome! Next time, I will use no sugar maple syrup and less sugar for topping. One question, will this freeze well?

    1. Hi Robert! We’ve not tried freezing this and think it might make the consistency less than desirable. Def let us know if you try it though!
