Few treats are as comforting and delightfully simple as a traditional all butter flapjack. With its rich, buttery base and chewy oat texture, this classic British bake is perfect for afternoon tea, a snack on the go, or even a cozy dessert served warm.

It’s the kind of recipe that invites creativity, but even in its most basic form, it remains deeply satisfying.
What Is an All Butter Flapjack?
A Traditional British Oaty Treat
All butter flapjacks are baked traybakes made primarily of rolled oats, butter, and a sweet syrup. They have a chewy, golden texture and a slightly caramelized flavor that comes from the combination of butter and golden syrup. In their purest form, they contain no flour or eggs, making them naturally simple and often suitable for those with dietary restrictions.
This treat is a favorite in British households, lunchboxes, and cafes, appreciated for its ease of preparation and rich taste. The ‘all butter’ variation emphasizes the use of real butter instead of margarine or oil, giving the flapjacks a deep, indulgent flavor and a satisfyingly soft yet chewy texture.

Step-by-Step All Butter Flapjack Recipe
Preparing the Mixture
Begin by preheating your oven to 180°C (160°C fan) or 350°F. Grease and line a square baking tin (approximately 20cm x 20cm or 8×8 inches) with parchment paper.
In a large saucepan, melt the butter over low heat. Once fully melted, add the golden syrup and brown sugar. Stir gently until everything is completely dissolved and you have a smooth, glossy mixture. Remove from heat before it boils.
Add a pinch of salt and stir in the rolled oats. Mix thoroughly, ensuring every oat is coated with the buttery syrup mixture. If you’re adding extras like raisins or a splash of vanilla, now is the time to mix them in.
Baking the Flapjacks
Pour the oat mixture into the prepared baking tin. Use the back of a spoon or spatula to press the mixture down evenly, smoothing out the top for even baking.
Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and the center is just set. Be careful not to overbake, as the flapjacks will continue to firm up as they cool. If you like softer, chewier flapjacks, take them out closer to the 20-minute mark.
Cooling and Cutting
Once out of the oven, allow the flapjacks to cool in the tin for at least 15-20 minutes before attempting to cut. They will be fragile when hot but will firm up nicely as they cool. Cut into squares or rectangles while still slightly warm, then leave them to cool completely before removing from the tin.
Tips for the Best All Butter Flapjacks
Getting the Texture Right
- Use rolled oatsrather than instant or quick oats. Rolled oats give the best texture and hold their shape during baking.
- Don’t overbake. The flapjacks should still look soft in the middle when removed from the oven. They’ll set as they cool.
- Line the tinwith parchment paper for easy removal and clean edges.
- Press down firmlyon the oat mixture before baking to prevent crumbling later on.
Flavor Variations
Customizing Your Flapjacks
Once you master the base recipe, it’s easy to personalize your flapjacks with added flavors or mix-ins. Here are a few delicious variations:
- Chocolate chip flapjacks: Add dark or milk chocolate chips after the oat mixture has cooled slightly to avoid melting.
- Fruit and nut flapjacks: Add chopped dates, dried cranberries, raisins, or a handful of chopped almonds or walnuts.
- Spiced flapjacks: Mix in a teaspoon of cinnamon, nutmeg, or mixed spice for a warm, comforting flavor.
- Salted caramel flapjacks: Drizzle with homemade caramel sauce and a sprinkle of sea salt after baking.
These simple additions can turn a basic all butter flapjack into a standout dessert or gift-worthy treat.
