Rolled Oat Bars with Brown Sugar and Golden Syrup

Introduction

Light brown sugar, butter, and a spoonful of golden syrup give these oat bars a dense, chewy middle and crisp edges after 40 minutes in the oven. You only need one saucepan and a 7½-inch square tin, so they work well for batch baking, lunchboxes, or a make-ahead snack.

Ingredients

110 g (½ cup or 4 oz) light brown sugar

175 g (1½ cups or 6 oz) butter

1 dessert spoon golden syrup

175 g (1½ cups or 6 oz) rolled oats

Instructions

Preheat the oven to 150°C (300°F or Gas Mark 2).

Place the sugar, butter, and golden syrup together in a medium saucepan and heat until the butter has melted.

Remove the saucepan from the heat and stir in the oats.

Press the mixture out over the base of a lightly-greased 7½-inch (19 cm) square baking tin.

Bake in the centre of the oven for 40 minutes.

When baked, allow to cool in the tin for 10-15 minutes before cutting into oblong bars.

Leave until cold before removing the flapjacks from the tin, then store in an airtight container.

Variations

• Replace the light brown sugar with dark brown sugar for a deeper caramel note and a slightly darker finish.
• Swap 25 to 50 g of the rolled oats for chopped nuts or seeds if you want more texture and a less uniform chew.
• Add ½ teaspoon ground cinnamon when you stir in the oats for a warmer, spiced flavor.
• Bake for 35 minutes instead of 40 if you want a softer, chewier centre, or add 5 extra minutes for a firmer bar with more crispness at the edges.

Tips for Success

• Heat the sugar, butter, and golden syrup only until the butter has melted; you do not need to boil it.
• Stir in the rolled oats thoroughly so there are no dry patches before you press the mixture into the tin.
• Press the mixture firmly and evenly into the corners of the 7½-inch tin so the bars hold together after cutting.
• Cut the bars after the 10 to 15 minute rest in the tin; if you wait until they are fully cold, the edges can break more easily.
• Leave the bars completely cold before removing them from the tin, or they may bend and crumble.

Storage and Reheating

Store the bars in an airtight container at room temperature for up to 5 days, or in the fridge for up to 1 week. If you want longer storage, freeze them in a sealed freezer container with baking paper between layers for up to 2 months.

They do not need reheating, but you can warm a bar in the microwave for 10 to 15 seconds if you want it softer. From frozen, thaw at room temperature first, or warm in a low oven at 150°C for about 5 minutes.

FAQ

Can you use quick oats instead of rolled oats?

Yes, but the bars will be softer and a bit less chewy. Rolled oats give better texture and hold their shape more reliably.

Why did the bars turn out crumbly?

They usually crumble if the mixture was not pressed firmly enough into the tin or if you tried to remove them before they were fully cold. Cutting them after the short cooling period also helps them set into clean bars.

Can you make these dairy-free?

Yes. Replace the butter with a block-style plant butter, and expect a slightly softer set.

Can you double the recipe?

Yes, as long as you use a larger tin and keep the mixture at roughly the same thickness. Start checking near the 40-minute mark, then add a few extra minutes if the centre still looks too pale or soft.
