Ingredients & substitutions

  • Coconut oil: Coconut oil helps to bind the ingredients together and add moisture, and it also adds a nice subtle flavor. You can substitute with unsalted butter or plant-based butter.
  • Sugar: Cane sugar is less processed than white sugar so it is preferred in this recipe, but you can substitute with any granulated sugar.
  • Egg: To bind the dry ingredients together. You can make this recipe vegan by using a flax egg.
  • Flours: Use a mixture of oat and all purpose flour to make these strawberry bars. If you have a gluten intolerance, you can swap the all-purpose flour for a 1:1 gluten-free flour. If you don’t have oat flour to hand, it’s quick and easy to make your own.
  • Cinnamon and salt: To enhance the flavor of the bars.
  • Strawberries: We use fresh strawberries for these bars, dice them fairly small so that they break down easily when they are baked. It’s best to avoid frozen strawberries as these can contain a lot of water.
  • Lemon juice: To help balance out the sweetness. Use fresh lemon juice rather than bottled for the best flavor.
  • Oats: Rolled oats, or old fashioned oats are best for this recipe, they keep a nice chewy texture and get nice and crispy too. In a pinch you can use quick oats, but it’s best to avoid steel cut oats that will be tough to eat.

Tips for making the bars

  1. Use juicy ripe strawberries. This will help them break down more easily with the sugar and lemon juice to create a jammy consistency when baked
  2. Chop the strawberries evenly. This will help make the filling more smooth and consistent instead of chunky. It also breaks down with the sugar more easily.
  3. Divide the base into portions to make it easier to add to the pan. Put several large dollops of the mixture in different parts of the pan and push them together with your fingertips.
  4. Don’t skip chilling the base layer. This will help the oat bars cook more evenly as the coconut oil will solidify so that the sugar can gradually absorb any liquid.

Frequently asked questions

How long do they keep?

Once your strawberry oat bars are baked, let them cool before cutting them in bars. Store them in an airtight container in the fridge for up to 4 days. They will not be as crisp after a couple of days, but can be reheated in the oven to get them to crisp up again if you wish.

Can you freeze them?

Yes, these bars will keep frozen well for up to 2 to 3 months. Once cooled, you can freeze the bars in the pan by covering with foil and placing in a freezer bag. You can also freeze individual bars by separating them with parchment and placing in an airtight container. Thaw in the fridge or at room temperature.

Can you use other fruits?

If strawberries aren’t your thing, or you have some fresh fruits to use up, the strawberries can easily be swapped. Blueberries, raspberries, peaches and mango are all great choices!
