Put 225 g of Frozen blueberries, 1 tbsp of Water, 1 tbsp of Lemon juice, 1 tsp of Lemon zest, 1.5 tbsp of Chia seeds and 1 tbsp of Maple syrup into a saucepan.
Bring to the boil then simmer for 5 minutes, mashing down the blueberries.Continue stirring while heating.
Once cooked, allow to cool to thicken.
For the Oat Bars
In a large mixing bowl, add 80 g of Oats (whole), 110 g of Oats (flour), 1 tbsp of Ground flaxseeds, 1 tbsp of Sunflower seeds, 0.5 tsp of Ground cinnamon, 2 tbsp of Coconut oil (melted), 1 tsp of Vanilla extract and 130 g of Peanut butter.
Mix everything together until well combined.
Tightly press ⅔ of the oat mixture into a lined tin.
We used a 19x13cm (7.5x5 inch) tin. A smaller tin will result in thicker bars, a larger tin will result in thinner bars.
Spread the cooled jam over the oat mixture.
Crumble the remaining oat mixture over the jam layer.
Carefully spread the crumbled oats mixture over the jam.
Refrigerate for 5 hours. Once chilled, cut into bars.
