Irish Oat Flapjacks


Rolling oats are used in Irish Oat Flapjacks. Just plain rolled oats. When baked, they become much crunchier and maintain their texture. The recipe is very simple and straightforward. The first step is to combine the golden syrup, butter, and sugar. When finished, stir in the oats. Place this on a baking sheet and bake for 25-30 minutes, till golden brown.

Irish Oat Flapjack Varieties

Irish Oat Flapjacks

  • You can add your favorite seeds and nuts. Almonds, sultanas, hazelnuts, pistachios, cranberries, and raisins go well.
  • Pumpkin seeds, chia seeds, flax seeds, and sunflower seeds can also be added. Whole chocolate chips can be added if you like some cocoa powder.




Golden Syrup Substitute

I understand that not everyone has on-hand golden syrup. If you want to substitute it, use maple syrup or honey or maple syrup. Treacle or molasses can also be substituted, but they have a rich flavor.
