You're going to LOVE my Healthy Frozen Berry Oat Slice Recipe. This is one of the very first recipes I posted to my site and it's been viewed over a million times, for good reason, it's the best.
You can tweak the recipe to be gluten-free with buckwheat and tapioca flour, dairy-free by using coconut oil and it's already egg-free, so no worries there.
Make a batch and pop it in the freezer for the babes lunchbox, my kids LOVVVVVE it!
Here's how to make a batch:
Melt the butter and mix it with all the dry ingredients in a bowl.
Press the mixture into a lined tin. Reserve 1/3 of it for the top layer.
Top with the berries and the remaining oat mixture and press it down firmly, so it holds together fab.
And this is her all cooked up. Pop her in the fridge or even freezer before cutting, that will help keep it perfectly together.
