An easy one bowl recipe that comes together with a just a few wholesome ingredients.

Mixed Berry Baked Oatmeal is made with ingredients you may just have on hand. You’ll appreciate that it takes just 15 minutes (or less) to prep and in the oven it goes. I personally prefer baked oatmeal over a bowl of oatmeal and that is because of the texture and how all of the delicious flavors come together. It’s sweetened ever so slightly with pure maple syrup and in combination with cinnamon, vanilla and mixed berries it’s truly something scrumptious. I like to serve it warm, right out of the oven, with a dollop of whipped topping or yogurt on top!  You’ll be mmm’ing at every bite.

Mixed Berry Baked Oatmeal is a dish to enjoy all year round.

This recipe calls for frozen berries, therefor it’s perfect to make all year one. I also want to note that it makes for a great meal prep recipe because it reheats nicely and you can even enjoy it cold if time is not on your favor and you need something quick. If you have another kind of frozen berries kickin’ around in your freezer, by all means, save yourself a trip to the grocery story and use what you have on hand.

Kalona Supernatural Organic Plain Kefir is being poured from a glass measuring cup into a bowl filled with rolled oats to make Mixed Berry Baked Oatmeal.

You may have thought that kefir was just for drinking but it’s also great for baking. Whole milk kefir adds richness to baked goods and can be used in place of buttermilk in pancakes, waffles, muffins, and more. I love the flavor and nutritional benefits kefir adds to this recipe and I highly recommend you make it as the recipe calls, however if needed feel free to substitute any milk of your choosing.

You can learn all about Kefir, what it is, and its benefits in our blog post, What Is Kefir?
