Starbucks Oat Bars

By: Bella Bucchiotti
Starbucks oat bars have been a favourite treat of mine for a long time. They are known as British flapjacks and you are going to love this copycat recipe as much as I do. These copycat Starbucks bars are perfect for a quick and easy breakfast, a midday pick-me-up.
Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes
Servings: 16


  • 10 Tablespoons salted butter
  • Cup turbinado sugar
  • Cup brown sugar
  • Cup golden syrup
  • ¼ Teaspoon salt
  • ¼ Teaspoon cinnamon
  • 2 ¾ Cups quick cooking rolled oats, quick cooking rolled oats


  • Prepare a 9x9 baking dish by lining the bottom and sides with parchment paper.
  • Preheat the oven to 350 degrees 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 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 9x9 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 degrees F. Bake at 325 degrees F 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 9x9 baking dish and place onto 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.
