I made these blackberry crumble bars as I had some leftover homemade chia jam and didn’t want it to go to waste. The bars give a nod to the classic crumble but make an ideal breakfast or snack on the go due to them being refined sugar free and made with ‘healthier’ ingredients.
I use blackberry jam in these bars but you could use any flavour berry jam you want. I have not made these bars using shop bought jam as there is a risk that the jam will spread during the baking process and the line of jam running through the middle of the bars will be compromised. For this recipe you will need to use butter from a hard block rather than a spread.
Ensure that you allow these bars to cool fully before removing them from the tray or slicing into them otherwise you risk them falling apart. I use a lined 8″ x 8″ brownie tray for these and it results in the perfect thin bake that I then cut into nine individual squares.
If you enjoy these bars you may also enjoy my Apple & Cinnamon Crumble Bars. These are best eaten within two days, however, will last up to a week in an airtight container.
