A delicious healthy treat and ideal as a breakfast option too. The combination of homemade marmalade and blueberries is a real winner and keeps the bars wonderfully moist. It also adds a natural sweetness meaning you can keep added sugars down. You could freeze these bars or store them in the fridge for about a week.

Blueberry Marmalade Oat Bars


Makes 16 bars

Preparation time: 15 minutes

Cooking time: 25-30 minutes


What’s Good About It?

A variation on the traditional oat slice but with added protein to support more balanced blood sugars. The use of olive oil provides healthy anti-inflammatory monounsaturated fats


  1. Preheat the oven to 180C, gas mark 4. Grease and line a 20cm square baking tin.
  2. Make the base. Place all of the ingredients in a bowl and mix to form a slightly moist dough. Press this into the base of the tin firmly.
  3. Scatter over the blueberries then drizzle over the marmalade or dollop spoonfuls if your marmalade is thicker.
  4. Make the topping. Place the ingredients in a bowl and mix – you should have a more crumbly topping.
  5. Scatter this over the berries and press down lightly.
  6. Bake in the oven for 25-30 minutes until golden brown. Allow to cool in the tin completely. I find it better to then chill the mixture before cutting into slices.
  7. Store these in the fridge for 1 week or freeze for up to 3 months.

Did you Know?

To keep the sugar content down use a pure fruit spread instead of regular marmalade but you may need to warm it slightly to make it more runny.  You can buy low sugar syrups made from inulin and stevia – I like this one
