If you’ve been reading my blog for a while, you might have noticed that many of the recipes will call for “milk of choice” as one of the ingredients.
People often ask me what this means, or what milk I personally use. My favorite, and possibly the most-used ingredient in my entire kitchen, is Blue Diamond Almond Breeze. It’s creamy, dairy-free and plant-based, and its unsweetened varieties (original, vanilla & chocolate) have less than 40 calories per cup. I go through so many cartons of almond milk that I usually buy them five or six at a time!
(And yes, in case you were wondering, this is SUPER FUN to carry home from the grocery store.)
Most often my go-to will be the Almond Cashew Unsweetened Original, which—thanks to having zero grams of sugar—is especially good for using in savory recipes like these Cheesy Ramen Noodle Bowls or my Ultimate Vegan Cheese Sauce.
I also make sure to always have a couple shelf-stable Almond Breeze (good for up to a full year) tucked into my pantry, because you never know when you might run out of refrigerated almondmilk halfway through making a recipe.
This is exactly what happened to me yesterday morning when I was making the peanut butter oatmeal, and having that shelf-stable Almond Breeze on hand saved the day. Or, it saved my breakfast plans at least!

Peanut Butter Cup Baked Oatmeal
Ingredients
- 1/3 cup peanut butter or allergy-friendly sub
- 2 2/3 cup overripe mashed banana (banana-free version here)
- 1 cup milk of choice – I like Almond Breeze Almondmilk
- 1/4 cup pure maple syrup OR additional milk of choice if you are used to the lower sweetness level of clean-eating recipes
- 2 1/2 tsp pure vanilla extract
- 3 cups rolled oats
- 1/2 cup cocoa powder
- 1 tsp salt
- optional chocolate chips and/or melted peanut butter for garnish
Instructions
- Be sure to use bananas that are partially or mostly brown before peeling, which means they're ripe. Preheat the oven to 350 F and either line a 9x13 baking pan with parchment or grease the bottom and sides very well. In a large bowl, stir together the first 5 ingredients until evenly combined, then stir in remaining ingredients. Smooth into the pan, top with chocolate chips if desired. Bake on the center rack 30 minutes, then do not open the oven door even a little, but turn the oven off and let the pan sit in the turned-off oven for an additional 20 minutes. Garnish with additional peanut butter or maple syrup if desired, and serve hot or cold. This tastes even better if you loosely cover and refrigerate overnight, so I highly recommend serving it the day after it's made. Leftovers can also be sliced and frozen for up to two months.View Nutrition Facts

I am so making this tomorrow after I go grocery shopping. Somehow I let myself run out of chocolate and pb. Oh the travesty of that!! Thanks for all the great recipes Katie!
Wow! This looks amazing! I might stir a little protein powder in mine.
Maybe chocolate protein powder in place of the cocoa powder? I’ll report back 🙂
I can’t see why that wouldn’t work. I use chocolate protein powder in my oatmeal all the time! However I add cocoa powder on top of that because I like it reallllyyyy chocolatey. 🙂
There really is no end to the chocolate madness! And I don’t think that’s a bad thing, either. What better way to make yourself feel more “at home” after a vacation then a delicious, chocolatey, healthy breakfast. Yum! Thanks for sharing 🙂
I’m all about chocolate for breakfast! Every once in awhile I’ll add some cocoa powder to my oatmeal or top it with a few chocolate chips! Yum!
I have made a baked oatmeal like this and I LOVE it!!! Your pictures are gorgeous!!! Yum!! I want htis for breakfast now!
I used to eat chocolate at breakfast, but always made my other meals bland in comparison 🙂
Have you ever made breakfast bakes like these with quinoa flakes? I can’t eat oatmeal because of my wheat allergies (even g-free cause me discomfort!). I’d really like to try this though, except without peanut butter (another stupid allergy).
If you figure out how to make this with quinoa flakes please let me know! And I totally agree about the other meals being bland after a chocolaty breakfast… Chocolate oatmeal sets the bar pretty high for the rest of the day. Haha.
Making this for lunch – I have pb2 and quick oats in the cupboard, so I’ll let you know how it turns out! So excited! 🙂
Those substitutions worked well – Other than that, I didn’t change a thing.
After a quick taste test, I decided to top it with some of your frosting (mine turned out more like a choc pb glaze, probably because I used pb2 again, but glaze was fine!) and some fat free french vanilla creamer – I like things to be on the sweet side, so the creamer and glaze were perfect additions!
SOOOOOOO YUMMY! Will definitely be making this again! Maybe even for dessert tonight since I’m having a friend over for dinner?!
Rave reviews from my friend and my parents – I whipped up 2 batches and poured the batter into a 6 muffin pan (which fits perfectly in my toaster oven so I didn’t need to heat the house!) – everyone loved it with and without toppings!
Toppings (individually and combinations thereof) we used were:
Frosting
Creamer
Whipped Cream
Crushed raspberry/strawberry combo with a sprinkle of stevia
Fantastic! Thanks for another great recipe!
Oh my goodness all your ideas sound SOOO good!! I think I’m going to make some right NOW to eat for breakfast tomorrow morning. Hopefully it will be as good if I refrigerate it….if I can wait that long. Hope I don’t end up eating it for dessert tonight. Anyhow…thanks for the ideas!!! Going to use quick oats myself!
OMG – I must make this over the weekend. I’m almost out of pumpkin boatmeal and this sounds fantastic!
I sometimes have chocolate at breakfast, but usually only in small amounts (chips in oatmeal or granola bars). It feels like I’m getting away with something by having chocolate so early, hehe. And hooray for research on sweet breakfasts! 😀
what a delicious way to start the day! yum!
this looks great! the title had me lol
looks great! I love all your recipes 🙂 I know you don’t focus on calorie counting since you’re not watching your weight, but I thought you might want to know that some of them are quite a bit off. In this one, 1/2 c of oats + 2 T of PB would be at 350 without any of the other add ins.
I know a lot of your recipes include variations (which is amazing, and so much work, I’m sure!), but it is a little misleading. And as someone who IS trying to monitor that, it was frustrating to realize I was drastically underestimating my intake unless I calculate them myself. I don’t mind, but I just wanted other people to be aware.
Love your blog… and impatiently waiting for tomorrow AM to try this 🙂
Hi Michelle,
In this one you would use 1 tbsp pb for the calculations, because whenever there’s a varied amount you should always go with the lower amount for accurate results. Hope that helps!
Michele, I am too counting calories, but I always calculate them first and if the recipes end up being too high in points for my intake I divide it into several servings so that I am not tempted to eat all the calories at once. For example the Baked Cookie Dough oatmeal I usually make it in a mini-muffin tin that makes 12 mini muffins (and I will probably do the same with this recipe), that way each muffin only has one WW point instead of 12. It has really helped me enjoy all of the CCK recipes and keep losing weight, hope this helps!
Have been meaning to try baked oatmeal to see what it’s like – this looks like a good one to start with! Just a quick question though – is this meant to serve as a full breakfast for one person? Had a look at the nutrition info and the whole thing is only 280 calories, which to me is more like a snack than a proper breakfast, especially for anyone who’s even remotely active! I’m a runner so there’s no way this would be enough for me to refuel on. Is there anything other than chocolate frosting you could recommend having with it to make it more of a substantial meal? I guess this question is for anyone who eats baked oatmeal for breakfast really – what do you usually have with it (if anything)? I guess I could just double the recipe, but it’d be great with some ideas for yummy accompaniments!
Yes, definitely. Use the higher amount of pb (the 2 tbsp) and you’re already up 100 calories. Then add the frosting or whatever topping you wish. And a smoothie or fresh fruit is a great side. All in all, it can become a 600+ calorie breakfast quite easily :).
I never understand why people post comments on here like this regarding the calorie content. In no way anywhere does this blog state that it is a meal plan blog. Also, so you are telling us, that whatever recipe you read off a blog or cookbook, you only make just that? So if you wanted to make lets say chicken for dinner (sorry, I know this is a Vegan blog but its what comes to mind) you look up a recipe and only make that because it doesn’t mention sides? You can’t think that for yourself? I don’t mean to come off sounding like a jerk but I am not understanding what makes this blog any different than any other recipe in that context.
When I make something like this I either add protein powder or hard-boiled egg whites (sorry, I am not Vegan so if you are you will have to research your protein options) or even fruit on the side, more nut butters, etc. In fact, I add protein powder to every one of Katie’s milkshakes and she still lets me read her blog even though I make minor changes here and there;)
Yummy! I LOVE your boatmeal for one recipes. My fiance and I can each pick what flavor we want 🙂 My favorite is banana bread, his is cinnamon roll.
This looks delicious. I prefer to incorporate more protein in my meals, but I bet adding a scoop of chocolate protein powder to this mix wouldn’t change the flavor profile too much and while boosting the protein.
Can’t wait to try this! I love peanut butter and oatmeal together. I have my very first baked oatmeal in the oven as we speak 🙂
This looks fantastic! I think I even have all the ingredients to make this (not sure what kind of oats I have though – rolled vs. quick). I may frost it with Nutella instead of making my own or eating it plain. YUM!
