Chocolate Brownie Oat Breakfast Bars

Brownies for breakfast? Yes please! These Chocolate Brownie Oat Bars taste like a real treat but are packed with healthy oats, perfect for a delicious breakfast the whole family will love.

Chocolate Brownie Oat Breakfast Bars served with a dollop of yogurt and fresh yogurt.

I’ve been obsessed with Breakfast Oat Bars the past few months. Having something ready made and in fridge that I can just heat up and give the kids in the morning is so handy.

And these Chocolate Brownie Oat Breakfast Bars are possibly my best yet. Believe me when I say I’ve been eating them for three days straight!

Chocolate Brownie Oat Breakfast Bars dived in to portion size squares.

To start add a mashed banana, one egg, honey, vanilla extract and milk to a large bowl and whisk until combined.

wet ingredients bring added to a glass mixing bowl

Then add in oats (just regular porridge oats are fine) along with some cocoa powder and mix again.

Dry ingredients being added to the mixing bowl.

Pour the mixture into a lined brownie dish and top with chocolate chips.

Any tin that’s roughly 8×8 inches in absolutely fine.

Mixture poured into an oven proof dish ready to be put into the oven.

Bake in the oven for 30 minutes then leave to cool for about 10 minutes before cutting into 9 squares.

This will ensure the bars are completely firm and makes it much easier to cut them.

You can serve them straight away. I like to serve the with some greek yogurt and fruit.

Or pop into the fridge or freezer for another day. All instructions on storing and freezing are in the recipe card below.

Ingredient Substitutions

Banana – The banana flavour is very subtle but if you’d rather not use it then you can substitute it for 120g of apple sauce

Egg – To make these bar egg free then use an egg replacer

Honey – This can be substituted for maple syrup or any type of liquid sweetener.

Milk – Dairy free milk will work just fine in this recipe

    Made these as a snack for my toddler. They taste okay, but the texture is not great (chewy / rubbery). They didn’t come out looking anything like the picture. I might try again, but blend the ingredients together first to achieve a smoother texture.

      If you make them again after you’ve added the oats and cocoa powder,mix again really well until combined, hopefully the next batch will be toddler approved! thanks for your feedback.
