made in minutes and the perfect lunchboxes filler you will make these again and again

Oatie Goodness

Aisling Larkin oat flapjacks

These flapjacks are made with the purest and most natural ingredients. They are not sugar-free or anything else like that. They are not meant to be. They are made with local Irish old-fashioned rolled oats, Irish butter from our local grass-fed Irish cows, Irish sugar, Irish sea salt and vanilla ( not Irish but get the very best quality one you can ). They are not processed or ultra processed. They are natural and homemade, buttery, sweet and the most delicious ( kinda wholesome) treat. The fruit and seeds are a lovely extra but I make these plain more often than not. I make this bigger batch, cut them into squares and store them in the freezer. Ideal with a cuppa on a rainy day, perfect for a picnic basket and ideal for when you are desperately searching for that “something else” in the lunchbox. I know your family will love my modern take on an old fashioned classic. 

With fun and deliciousness,
