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

This is delicious! I made it tonight using the extra dark chocolate cocoa. It reminds me of no bake chocolate peanut butter oatmeal cookies, but BETTER! And HEALTHY. Everything in this is good for you. I used raw honey for my sweetner in the icing, plus all natural crunchy peanut butter. I cooked mine in a muffin pan. It made 4. Thanks for this great recipe.
I made this tonight, I used PB2 and a scoop of vanilla protein powder, left out the extra stevia since my protein powder is already sweetened with it. Yum! I had just a bite and I will be eating it for breakfast tomorrow.
I made a double batch last night! Oh my gosh it was one of the best things I have ever had. It is going to be my go to “dessert” when I want the taste of a brownie, Bravo.
So I have to say I quadrupled this recipe from the get go. I quickly learned that it is two bananas and it makes a perfect 12 regular size muffins or 6 large muffins. I can’t get enough of these or the other stuff you have created, Katie. I’m on a special diet for my little one and nearly all of your recipes work! My husband even loves them, too!
This was SOOOO good! Thank you for the recipe! I have the Cinnamon Roll Baked Oatmeal in the oven now. I’m sure it will be just as good 🙂
My new favorite breakfast! So delicious! LOVE LOVE LOVE it!
Made this for breakfast this morning; I must say it is so yummy! Thank you for sharing all of your healthy recipes. It makes me feel so much better knowing I’m eating something this good and knowing it is better for you as well! The taste to me is almost like a chocolate banana bread! Thanks Again, can’t wait to try the others!
Hi Katie!!
i might be a little late with this comment but can you try this with the voluminous oatmeal trick? or would letting it sit and baking it cancel the voluminous effect out? i really wanna try this soon!! 🙂
I adapted this for a microwave here. Thanks for a lovely recipe!
Mine looked more chocolate-y (not a bad thing..) than your photo, but holy wow batman, tastes amazing. Giving this the BLD (Breakfast/Lunch/Dinner) Treatment!
