Jamie Oliver Flapjacks Ingredients List

• 200 g unsalted butter
• 200 g golden syrup
• 100 g light brown sugar
• 400 g rolled oats
• Pinch of salt

How to Prepare Jamie Oliver Flapjacks – Simple Steps

Step 1: Prepare the baking tin

Preheat the oven to 180°C (160°C fan). Line a square baking tin with baking paper, making sure the paper comes up the sides. This makes lifting and slicing the flapjacks much easier once baked.

Step 2: Melt the butter mixture

Place the butter, golden syrup, brown sugar, and salt into a saucepan. Heat gently over low heat, stirring often, until everything melts into a smooth, glossy mixture. Avoid boiling, as high heat can affect the final texture.

Step 3: Combine with oats

Remove the saucepan from the heat and add the rolled oats. Stir thoroughly until all the oats are evenly coated. This step is important for ensuring the flapjacks hold together and bake evenly.

Step 4: Press into the tin

Transfer the oat mixture into the prepared tin. Use the back of a spoon or spatula to press it down firmly and evenly. Pressing well helps the flapjacks set properly and prevents crumbling later.

Step 5: Bake until just set

Bake in the preheated oven for 15–20 minutes, until the top is lightly golden. A shorter bake gives softer, chewier flapjacks, while a slightly longer bake creates firmer edges.

Step 6: Cool and slice

Remove from the oven and leave to cool in the tin for about 15 minutes. While still warm, lift out and slice into squares or bars. Cutting at this stage gives cleaner edges and prevents cracking.

FAQs

Why Do My Flapjacks Fall Apart After Baking?

Flapjacks usually fall apart when the mixture isn’t pressed firmly enough into the tin or when they are cut after cooling completely. Pressing the oats tightly and slicing while still warm helps them hold together.

How Do I Make Flapjacks Chewier Instead of Crunchy?

For chewier flapjacks, bake them for a shorter time and remove them when the centre is still soft. Overbaking dries them out and makes them hard once cooled.

Can I Use Honey Instead of Golden Syrup in Flapjacks?

Yes, honey can replace golden syrup in equal amounts. The flavour will be slightly different, but the flapjacks will still bind well and have a pleasant sweetness.

How Long Do Homemade Flapjacks Last?

When stored in an airtight container at room temperature, flapjacks stay fresh for up to 5 days. Keeping them sealed properly helps maintain their chewy texture.
