Step-by-Step Guide to Making Mary Berry Flapjacks

Step 1: Preheat the oven and prepare the tin

Preheat the oven to 180°C (160°C fan) / 350°F. Line a 9-inch square tin with parchment paper, leaving a slight overhang for easy removal.

Step 2: Melt the butter mixture

Add butter, sugar, and golden syrup to a saucepan. Stir over low heat until melted and combined. Do not let it boil—just warm enough to dissolve the sugar.

Step 3: Add the oats

Remove the pan from heat and stir in the rolled oats until they’re well coated with the syrup mixture. The oats should look glossy and sticky.

Step 4: Press into the tin

Spoon the mixture into the prepared tin and press it down evenly using the back of a spoon or spatula to compact it slightly.

Step 5: Bake until golden

Bake for 20–25 minutes, or until the edges turn golden brown. The center will still look soft but will firm up as it cools.

Step 6: Cool and slice

Allow to cool in the tin for about 10 minutes, then mark out squares or rectangles. Leave to cool completely before lifting out and cutting fully.

What I Got Wrong (And How I Fixed It)

• Overbaked the flapjacks – Made them too hard; next time, I removed them once the edges browned.
• Didn’t press the oats firmly enough – Caused crumbling; pressing down helps hold shape.
• Used quick oats – Resulted in a mushy texture; rolled oats give the right chew.
• Cut while warm – Broke apart; letting them cool made slicing easier.

• Swap half the butter for coconut oil or nut butter.
• Replace golden syrup with honey or maple syrup.

FAQs

Why did my Mary Berry flapjacks fall apart after baking?

Flapjacks often crumble when the mixture isn’t pressed firmly into the tin or is cut while still hot. Always compact the oats well before baking and allow the flapjacks to cool completely before slicing to help them hold together.

How do I make Mary Berry flapjacks chewy instead of hard?

To achieve chewy flapjacks, bake them until they’re just golden at the edges but still soft in the middle. Overbaking causes them to turn hard once cooled, so remove them from the oven a few minutes early for a softer texture.

Can I replace golden syrup in Mary Berry flapjacks with honey or maple syrup?

Yes, golden syrup can be swapped for honey or maple syrup in equal quantities. However, honey gives a softer texture and slightly different flavor, while maple syrup adds a subtle caramel note. Golden syrup remains the best choice for traditional chewy results.

How do I stop flapjacks from sticking to the baking tin?

Line your tin fully with parchment paper and lightly grease it with butter or oil before adding the mixture. Let the flapjacks cool for 10 minutes in the tin before lifting them out to prevent sticking or breaking.
