Top tips for making this granola bar recipe

Looking for substitutions for porridge oats or golden syrup? We have some helpful tips below for how to make this granola bar recipe without those ingredients. 

What can I use instead of porridge oats?

Swap the porridge oats for your favourite muesli if you like. Try to buy unsweetened cereal otherwise you may find the finished granola bars taste too sweet. If you buy something with fruit and nuts already mixed in you might choose to increase the weight of cereal used in the recipe and omit the added fruit and nuts. 

Can you replace golden syrup with honey in flapjacks?

Yes you can use honey instead of golden syrup. However, it will change the flavour of the finished bake. Also keep in mind that golden syrup is suitable for vegans for many vegans do not eat honey. 

Is granola healthy or fattening?

Many granolas, whether homemade or shop bought, contain lots of nuts and fruits which means they are nutritious and filling. Some granolas will have lots of added sugar or may have been baked with lots of butter which can increase the fat content. 

Granolas that are rich in nuts will also have a higher fat count but this doesn’t make them unhealthy. Granola is a popular breakfast choice and can keep you feeling fuller for longer. The syrup and sugar in this granola bar recipe means that they should be consumed as a treat as part of a balanced diet. 

We bake these granola bars in an 18cm square tin. You can use a bigger or larger tin but you may need to adjust the cook time. If you’d like to buy a new tin, this one from MasterClass is a great option.

The non-stick coating and loose bottom of this tin will make removing your flapjacks from the tin a simple and easy task. It’s a nice shaped tin for making other bakes including brownies, focaccia, or even Christmas cake. 

Oatmeal bars or this healthy flapjack recipe are great options for those searching for lower calorie treats. Alternatively if you’d prefer more indulgent, our chocolate chip granola bar hits the brief.
