Why Homemade Flapjacks Are the Ultimate Hiking Snack (and Where the Name Comes From)

Whether you’re scaling peaks or strolling coastal paths, homemade flapjacks are a hiker’s best friend. These chewy oat bars are compact, calorie-dense, and packed with slow-release energy, thanks to their core ingredient of oats.

However, the addition of honey and syrups (like golden syrup or maple syrup) provide quick-release energy. These are simple sugars that are rapidly absorbed into the bloodstream, giving you an immediate energy boost. This is especially useful during a hike when you need a fast pick-me-up after exertion or to prevent fatigue. We’ve collected together 10 flapjack recipes for hikers, with different ingredients for a slight twist on the traditional hikers flapjack.

Add-ins like nuts, seeds, and dried fruit boost their nutritional profile with protein, fibre, and essential minerals, making them ideal for sustained energy on long walks. Unlike many packaged snacks, homemade flapjacks should be totally free from preservatives and can be tailored to suit dietary needs, from vegan to low-sugar.

Why are they called Flapjacks?

Flapjacks aren’t just practical, they’re steeped in British culinary history. The term “flapjack” dates back to the 1600s, originally referring to flat cakes or fruit tarts. “Flap” meant to flip or turn in a pan, and “jack” was a common term for an everyday man’s food. Over time, the name evolved, and by the 20th century, it came to describe the oat-based traybake we know today. In the UK, flapjacks are a beloved snack, often found in lunchboxes, cafés, and rucksacks, especially among walkers and climbers who swear by their energy-boosting powers.
