Ingredients

Instructions

  • Prepare a 9-inch square baking dish by lining the bottom and sides with parchment paper.
  • Preheat the oven to 350°F.
  • In a medium saucepan combine the butter, turbinado sugar, brown sugar, golden syrup, salt, and cinnamon.
  • Melt the mixture together over medium heat until the butter has melted and the brown sugar has mostly dissolved, the turbinado sugar will remain crystallized. Remove from the heat.
  • Add the oats to the saucepan and mix into the butter sugar mixture until the oats are fully coated.
  • Press the oat mixture into the prepared baking dish. Pat the mixture down with a spatula so that the top is a flat and even surface.
  • Place the bars into the oven and close the door, immediately reduce heat to 325°F. Bake for 25 minutes or until the edges are lightly golden brown.
  • Remove the bars from the oven. While they are still hot and in the pan, cut the flapjacks into 16 pieces. Leave the flapjacks in the pan to cool.
  • Once the oat bars are completely cooled, carefully lift them out of the baking dish and put them on a cutting board.
  • Use a sharp knife to re-cut the 16 pieces. Separate the pieces and either serve immediately or store in an airtight container.

Notes

Press them down firmly: This is one of the most important steps. I use a spatula to really compact the oat mixture in the pan before baking, which helps the finished bars hold together.
Use the right oats: Quick-cooking rolled oats give these bars their characteristic texture. Different oat types and even different brands can change how wet or dry the mixture seems.
Don't overbake: Take the bars out when the edges are lightly golden if you want that chewy middle. A few extra minutes will give you a firmer, crisper bar.
Cut them twice: Score the bars into 16 pieces while they're still hot, but leave them in the pan to cool completely. Once they're cool, go over the cuts again with a sharp knife.
Let them cool completely: This really matters. The bars firm up considerably as they cool, so don't judge their final texture while they're still warm.
