If you've just made a big batch of flapjacks and are wondering if you can freeze them, you've come to the right place! Whether you're prepping lunchbox snacks for the week or just want these sweet treats to last longer, knowing how to store flapjacks properly makes a big difference in texture and flavour.
For all my top flapjack advice, from baking time to the perfect ingredient ratios, check out my Flapjack Tips Guide.
Can You Freeze Flapjacks?
Yes, flapjacks freeze very well. It's one of the best and easiest ways to keep them tasting fresh for longer! As long as they've fully cooled and are stored appropriately, flapjacks will keep in the freezer for up to about 3 months without any difference in taste or texture.
This applies to plain, classic flapjacks and most flavour variations like peanut butter flapjacks, chocolate flapjacks and raisin flapjacks, but those made with fresh fruit may become slightly soggy after defrosting.
How to Freeze Flapjacks
- Cool them first: They need to be completely cold when you put them in the freezer; otherwise, the heat will trap moisture and make them soggy.
- Cut them before freezing: I recommend cutting the flapjack into squares or bars before you freeze it. This way, you'll be able to take one or two out as and when you fancy, rather than having to defrost the entire slab.
- Wrap them well: You can freeze flapjacks in an airtight container, in freezer bags, or wrap them tightly in cling film or foil. If you're stacking slices, put small pieces of baking paper between them to prevent them from sticking together as they freeze. Alternatively, freeze them on a baking tray for an hour or two until they're solid, then pop them into the container, bag, clingfilm or foil.
- Label them: Add the date on your packaging so you can see how long they've been frozen for.
How to Defrost Flapjacks
Defrosting flapjacks is super easy. You can let them thaw on a plate at room temperature for an hour or so, or pop them in the fridge overnight to defrost more slowly. If you're desperate to eat your flapjack right away, pop it on a microwavable plate and microwave for about 20-30 seconds until soft.
Once they've been defrosted, you can enjoy them as you normally would, but they should not be refrozen.
Fridge & Cupboard Storage
If you're not freezing them, you can keep your flapjacks in an airtight container or wrapped tightly in clingfilm or foil. Keep them in a cool, dry place (like your kitchen cupboard) and they'll last for around 5 days.
If you want to make them last for up to a week, pop them in the fridge in an airtight container or wrapped tightly as above.
Freezing is your best bet if you want to keep them for a long time without sacrificing the texture or taste.
In summary, you can definitely freeze flapjacks, and it's one of the best ways to prolong their deliciousness and avoid food waste. Perfect for meal prep or keeping a stash ready for lunches and snacks!
