Bumble Berry Oat Crumble Bars


During summer months, I love to hit up the local farmer's market. Unfortunately I often go there when I haven't eaten and my eyes quickly become much bigger than my stomach. The summer of 2015 was no exception, That's when the "Oat Crumble Bar" was born and quickly changed mine and Eric's life for the better. 

So what's my favourite market find? BERRIES! Berries of all kinds, shapes and colours. I always buy too many, and can't eat them fast enough. Originally, this recipe developed as a way for me to use up all those extra berries, but now I buy frozen berries just so I can make this all year round. It's one of Eric's real favourites, and we hope you enjoy it too! 

Here you will find a desert packed with fibre (from oats), vitamin C, and antioxidant rich phytonutrient "flavonoids" (from the berries). 

Enjoy these bars warm and gooey from the oven, or cool and partially frozen from the freezer, either way it's a win!
