Peanut butter flapjack updates the classic oat bar with peanut butter and jelly flavours. Oaty. Syrupy, nutty and fruity – all in one bite.
Try a slice with a peanut butter & jelly milkshake alongside it!
Having spent some extended time in Florida in my student days, I’m rather partial to America, Americans and some of the classic American goodies on offer. These days, although I’m English, many of my readers are American. So, my American friends, past and present, peanut butter flapjack recipe is for you. And…. these bars come laden with a secret layer of jam.
I know that really I should be calling jam ‘jelly’ to be truly in keeping with the American slant I’ve given this recipe. However I am English and I’m here, in England, writing this post. I feel obliged to write as I talk: British-English not American-English. Two very different languages, it seems.
And while I’m on the subject, let’s clear up the term flapjack. Flapjack is the British-English term for what American-English labels oat bars. The word flapjack does exist in American-English but often refers to what we Brits call pancakes. So, to be crystal clear (and slightly anal), these so-called ‘peanut butter flapjacks’ are actually peanut butter oat bars. They are definitely not pancakes, but, haha, I think you’ve probably already worked that one out from the photographs.
Anyway, back to those peanut butter flapjacks.
Imagine a hearty wedge of flapjack packed full of oaty and syrupy flavours.
Then imagine a bunch of friendly peanuts waltzing onto the scene. These peanut butter flapjacks are exactly that thought. Dense, buttery, syrupy, nutty – all those ingredients working together in harmony to make each bite perfectly balanced and delicious.
But this is more than peanut butter flapjack. This is peanut butter flapjack with a sneaky, ever-so subtle, layer of deliciously fruity jam peeking out of the middle. Essentially, it’s a peanut butter and jam sandwich transported into the world of flapjack. And that is a pleasant world to visit.
For more tasty flapjack recipes try my Biscoff flapjack and cocoa flapjack. They are both deliciously different. But steering in a slightly different direction, take your oats alongside a helping of cornflakes in my popular date bars.
How to Make Peanut Butter Oat Bars
Oat bars are one of the easiest treats to bake and my peanut butter with jam flapjacks are no different.
- begin by melting the butter, syrup and peanut butter together in a large pan
- Stir until well mixed and then add the oats and vanilla extract
- Spoon approximately half of the oaty mixture into a prepared tin and push down firmly to completely cover the base
- Spread a thin layer of jam over the oats and then top with the remaining flapjack mixture, levelling off as before
- Bake until golden then slice and let cool in the tin
Easy. Absolutely no fancy skills or equipment are needed to make these peanut butter oat bars.
The great thing about food is that it doesn’t matter what language you speak. Jelly or jam. Flapjack or oat bar. The result here is the same.
Flapjack + Peanut Butter + Jam = happy times
This peanut butter flapjack is hearty, comforting and guaranteed to make you feel warm and fuzzy just at the right moment.

📖 Recipe
Peanut Butter Flapjack
Ingredients
- 275 g/ 3 ¼ cups Rolled oats
- 175 g/ ¾ cup Unsalted butter
- 75 g/ 5 tablespoon Golden syrup
- 75 g/ ⅓ cup Light soft brown sugar
- 1 teaspoon Vanilla extract
- 3 tablespoon Peanut butter (I used crunchy)
- 3 tablespoon Grape jelly (or seedless raspberry jam)
Instructions
- Grease an 8 inch round baking tin with butter then line the base with baking parchment
- Preheat the oven to 170°C/ 325°F/ GM 3
- Put the butter, sugar, syrup and peanut butter into a large, heavy pan. Heat gently, stirring frequently until everything has melted & combined to form a deep golden liquid
- Take off the heat. Stir in the vanilla extract and the oats until thoroughly combined
- Spoon approximately half of the oaty mixture into the tin and push down firmly to completely cover the base
- Spread the jam (jelly) over the oats
- Carefully top the jam with the remaining oat mixture – use a spoon to put small dollops across the jam and spread out using the back of the spoon. Ensure that all of the jam is covered to prevent it from bubbling up and that the oats are firmly pressed down
- Bake for 25-30 minutes until golden
- Remove from the oven and allow to cool for 15 minutes. Using a sharp knife, mark out portions on the flapjack. Run the knife around the edge of the flapjack to loosen it from the sides of the baking tin
- When completely cold, remove from the tin and cut out the marked portions
- Store for up to 3 days in an airtight tin
