Crisp and golden on the outside, soft and fudgey on the inside… these blondies make a totally delicious and filling snack! They have all the texture of a brownie, yet the ingredients are guilt-free and they make the perfect snack for before or after a workout. 


Naturally sweetened with banana and totally grain and gluten-free, their density and rich flavour comes from the peanut butter. But any type of nut or seed butter will work just as well!

I love to keep them simple and flavoured with a pinch of cinnamon, but you could add in your favourite dried fruit, berries or coconut flakes for some added texture… or even some chocolate chips for an even more indulgent taste 😉
