Preheat oven to 170°C (340°F).

In a large bowl, combine rolled oats, cocoa powder, and salt.
Melt the wet ingredients:
In a saucepan over low heat, gently warm the peanut butter, melted coconut oil/butter, honey/maple syrup, and vanilla.
Stir until smooth.
Combine everything:
Pour the warm mixture over the oats and mix well until all oats are coated.
Add chocolate:
Fold in the chopped Whitakers dark chocolate.
For more melty pockets, leave some pieces larger.

Laura's Top Tips for This Recipe
I find it best if you use smooth nut butter straight from the jar at room temperature. It mixes so much more easily with the oats and cocoa and stops any lumps forming.
When I tried it this worked best for me: pressing the mixture really firmly into the lined tin using the back of a large spoon or spatula. It helps the flapjacks hold together perfectly once baked and cut.
I always melt the chocolate in short 20-second bursts in the microwave, stirring well each time. That gives the smoothest drizzle or topping without it seizing up.
One thing I learned the hard way is to let the flapjacks cool completely in the tin before slicing. It gives them that lovely chewy texture and they slice cleanly into neat squares every time.
A Brief History Flapjack in the UK
The term flapjack first showed up in England around the early 1500s, pointing to a flat tart or cake.
Shakespeare even mentioned flap-jacks in his play Pericles, Prince of Tyre, showing it as a common sweet at the time.
Over the years, it came to mean something like an apple flan.
By 1935, the name shifted to describe the oat-based bars we know today, baked with rolled oats, butter, and sweeteners such as golden syrup or honey.
These chewy treats grew popular in the UK as a simple, home-baked snack, often cut into squares and enjoyed with tea or packed for outings.
They remain a staple in British kitchens for their easy recipe and wholesome appeal.
