You only need simple ingredients for this incredible chocolate peanut butter baked oatmeal. This is what you need:
Rolled oats - we love using large old fashioned rolled oats for this because it gives the best texture.
Cocoa powder - use whatever cocoa powder you can get hold of, even use cacao powder if you like, for a richer chocolate flavor.
Peanut butter - there are a gazillion types of peanut butter out there, but we like to use a natural creamy one. This is because you’ll find it difficult to incorporate the ones that are set with palm oil into the mixture.
Maple syrup - sweetness comes from the maple syrup and it adds a depth of flavor too. Feel free to substitute with another liquid sweetener like honey or agave syrup or even golden syrup if that’s what you have.
Chocolate chips - we use the big bag of chocolate chips from Costco, but use whatever ones you like. The recipe is for DOUBLE chocolate, so don’t skip these!
We know you love mixing things up so here are some suggestions for customizing our chocolate peanut butter baked oatmeal:
Dairy free - if you wish to make this baked oatmeal dairy free, simply use dairy free alternatives for the milk and the chocolate chips.
Single chocolate - don't fancy the double chocolate? Omit the cocoa powder and simply make a peanut butter baked oatmeal with chocolate chips instead.
Nut butter - change up the nut butter. We love the peanut butter in this baked oatmeal but you can sub with almond butter, cashew butter, hazelnut butter or whatever you like.
Nuts - switch out the chocolate chips with a handful of your favorite chopped nuts.
Muffins - pour the mixture into a greased muffin tin and make baked oatmeal cups. You will likely need to bake for less time than the full size one.

This baked oatmeal so simple to whip together and it’s a great one for the kids to get involved in too! Here’s how:

👩🍳 Expert tips
Follow these expert tips to ensure success every single time when making this chocolate peanut butter baked oatmeal:
Grease - prepare an 8 x 8 baking dish by greasing with butter or oil. This just helps it not stick so much.
PB - make sure you use creamy natural peanut butter otherwise you'll find it really hard to incorporate the PB into the wet ingredients unless you use a hand mixer. This increases the amount of air in the mixture though.
Step by step - make sure you whisk the egg and peanut butter together with the maple syrup before adding the milk gradually. It'll help create a uniform mixture with no lumps.
Make ahead - make this baked oatmeal ahead of time for ease and just reheat it in the morning.
Can I bake it ahead of time?
YES! Absolutely, then just heat it back up as you desire the next morning or for a few days after. Just reheat in a 180oC/350oF oven for 10-15 minutes until hot in the middle and the chocolate is all gooey. Or reheat portions in the microwave. You can bake the oatmeal 3-4 days ahead. Just follow the baking instructions first time round and then store in the fridge.
This is the perfect breakfast/brunch/dessert for any festive occasion or just as an unapologetically delicious weekend breakfast or brunch.
