I’m absolutely ADDICTED to my slow cooker. I use my slow cooker several times a week for everything from breakfast to dinner to dessert recipes. There is something that is just so comforting with being able to set it and forget it, if you know what I mean. I can put everything into the slow cooker, go about my day – either getting work done, running errands, doing chores around the house – and I come back to a delicious meal!

This slow cooker chocolate peanut butter banana oatmeal bake the epitome of breakfast goals! You can either use the low or high setting for this one – the oatmeal bake takes about 2 hours on the high setting or 4-6 hours on the low setting.

I’ve done both depending on what I’m doing. Sometimes I like to just wake up, put this in the slow cooker on high and two hours later I have a great breakfast that is all ready to go. Other times, when I have more time (or when I’m sleeping!) I use the low setting, which is also super convenient.

I use a 6 quart slow cooker, which I think is important to note, as when you use a different size the recipe time will be either shorter or longer. If you’re using a 2-3 quart slow cooker, I would recommend cutting this recipe in half for best results.

Honestly, one of the more IMPORTANT things about this recipe is spraying that slow cooker insert GOOD with cooking spray. I love using PAM Pump Spray for this – the great thing about it is you can control how much you want to spray and always use the perfect amount! I also love that PAM Pump Spray has no artificial colors, flavors or preservatives and is only 3 ingredients.

I purchased my PAM Pump Spray at my local Meijer store, which is where I purchased my Peter Pan peanut butter for this recipe too! Peanut butter is a great way to add some protein to this breakfast recipe.

You’re just going to love how easy this slow cooker chocolate peanut butter oatmeal bake recipe is! It only takes a few minutes of preparation before you toss it all in the slow cooker. It’s a great recipe to feed a crowd or as meal prep for the week! What more could you want in a gluten-free breakfast, right?

  1. You lost me at PAM. That stuff is literally poison.

  2. This sounds delicious but could you substitute the flax and water for 2 eggs?

    1. Yes! I think that would work just fine 🙂

  3. Same instructions for an instapot as for slow cooker?

    1. Sorry I have not tested this in an Instant Pot yet!

  4. 5 stars
    Can you reheat for morning???

    1. Yes definitely! I usually just microwave individual slices or pop it in the oven until warmed through.
