Good to know

Chef's tip

For an even more indulgent version, you can add chocolate chips or dried fruit before baking. Let the flapjacks cool completely before cutting them so they don't crumble.

Freezing : Can you freeze this recipe?

Yes

Very well. Up to 3 months in individual portions tightly wrapped in a freezer bag.

Storage : How long does it keep?

Keeps 5 to 7 days max at room temperature in an airtight container.

Making ahead : Can you make it the day before?

Yes

Ideal for making the day before. Lets the flavors develop and the texture set.

Reheating : How do you reheat it?

Not necessary, eaten at room temperature. To restore softness, 10 seconds in the microwave or 5 minutes in the oven at 100°C.

Variations

  • Cut into bars or squares once cooled.
  • Press the mixture down firmly with the back of a spoon.
  • Serve as an afternoon snack or an energy bar.

Mistakes to avoid

  • Boiling the butter-sugar-honey mixture: heat over low heat.
  • Removing from the pan before it has cooled completely: it firms up as it cools.
  • Not pressing the mixture down well: the bar would crumble.

Frequently asked questions

How do you make the flapjack mixture?

Melt the butter with the brown sugar and honey over low heat, stirring, without letting it boil, remove from the heat, then add the oats and salt, mixing until well coated.

Why press the mixture down?

Press down firmly with the back of a spoon or a spatula to get a compact, even surface: this is what helps the bars hold together once cooled and cut.

How long do you bake the flapjack?

Bake for 20 to 25 minutes at 170 °C, until the top is lightly golden and the edges are crisp. The center may still look soft, which is normal: it firms up as it cools.

When should you cut the bars?

Let it cool completely in the pan without touching it, while the flapjack firms up, then remove it from the pan and cut it into bars or squares for snacking.
