It’s back-to-school day for the Lee’s! Oh goodness… I’m so not ready for the hustle and bustle. However, it is nice to get the kids on a stable routine. I’m probably a little too relaxed in the summertime with meal planning and sometimes our healthy eating goals go out the window. But that’s OKAY. In my opinion, it’s all about balance and enjoying life.

The Importance Of Grassfed Milk

Today we are partnering with our friends at Horizon Organic for one of my favorite make-ahead breakfast options. Not only is Horizon® Organic Grassfed Reduced Fat Milk refreshingly creamy and wonderfully tasty, Horizon Grassfed Milk is made from cows who spend 150 days per year per organic standards on lush pastures where they graze freely with access to shade, shelter, fresh air and clean drinking water.

I strive to do as much as possible to better the environment and that’s why it’s super important to me to buy Horizon Organic Grassfed Milk. It’s a great feeling to know that Horizon Organic does not use toxic and persistent pesticides, antibiotics, or added hormones on its cows – and its products are non-GMO. Plus, not all grassfed products are certified. Horizon Organic Grassfed Milk partners with the American Grassfed Association to provide your family with Certified Grassfed Organic Milk.

What You Need For Baked Oatmeal Cups 

Before we jump into the actual recipe, let’s talk about what you need for these baked oatmeal cups. Now, we’ve got lots of baked oatmeal recipes at Kim’s Cravings, but we LOVE oatmeal cups because they triple as a breakfast, snack, and dessert! Here’s what you need…

  • Old Fashioned Rolled Oats
  • Bananas
  • Eggs
  • Maple Syrup (or honey)
  • Milk
  • Pure Vanilla Extract
  • Ground Cinnamon
  • Baking Powder
  • Salt
  • Your Favorite Fun Add-Ins

How To Make Customizable Oatmeal Muffins

This oatmeal cup recipe is SO easy, even the kiddos can get in on the action!

STEP 1: PREP

First, preheat oven to 350ºF and spray a muffin tin with non-stick cooking spray. Then, set aside. Grab all of the ingredients and don’t forget some fun toppings to make these oatmeal cups your own. It will make baking these muffins easier to go ahead and measure all of the ingredients now. This is also the time when you’ll want to grind 1 1/2 cups of the rolled oats into oat flour. Use a blender or food processor to grind the oats until they have reached a flour-like consistency; set aside. Alternatively, you can purchase already ground oat flour.

STEP 2: MIX WET INGREDIENTS

Place a ripe banana in a large mixing bowl and mash. If you don’t have a super ripe banana, you’ll just need to mash it a little bit more with a fork to get the consistency you’re looking for. You can even use your blender or food processor for this step. After your banana is fully mashed, whisk in Horizon Organic Grassfed Milk, vanilla extract, maple syrup (or honey) and eggs until fully combined.

STEP 3: COMBINE INGREDIENTS

Then, add the dry ingredients (rolled oats, oat flour, baking powder, cinnamon and salt) to the wet ingredients. Stir until all ingredients are completely combined. Allow the banana/oat mixture to sit for about 10 minutes to allow the oats to soak up the liquid.

STEP 4: FILL THOSE MUFFIN TINS

Transfer the batter into your muffin tin, making sure to fill each muffin cup to the top. Next, have some fun and top the oat batter with all different toppings! I made four different versions and used fresh plums, chocolate chips, dried cranberries with shredded coconut and almond butter with chopped pecans. Lightly, press the toppings down into the batter.

STEP 5: BAKE

Bake at 350ºF for about 20-23 minutes. While your oatmeal cups are baking, start to consider what you’re going to store them in! These beauts will store for up to one week in an air tight container or zip-top baggie in the fridge, making it easy peasy for you to grab one and go every morning throughout the week. If you’re looking to keep these for a little longer, feel free to store them for up to 3 months in an air tight container or freezer safe zip-top baggie in the freezer.

Recipe Notes

*Alternatively applesauce or puréed pumpkin could be used in place of the banana.
**My topping choices for the muffins, pictured, are chopped fresh plums, chocolate chips, dried cranberries with shredded coconut and almond butter with chopped pecans. Alternatively, if you aren't concerned with making custom muffins, fold into combined batter approximately 1 cup fruit, raisins, nuts or other add-in of your choice.
