So apparently I’m on an oatmeal kick? I shared Strawberry Oatmeal Bars last week and Blueberry Oatmeal Muffins before that and now Oatmeal Coffee Cake! I love me some oatmeal.

Before we got our Vitamix blender, I would eat oatmeal every morning for breakfast. Maybe when I’m sick of green smoothies, I’ll head back to oatmeal every morning again.

My boys are cereal lovers. I honestly can’t believe how many boxes I go through with four boys. My older two can put down a box in two mornings. My two little guys love cereal too.

I’m sort of bad about making a huge breakfast on school days, so cereal is the best option for me. But on the weekends, I love cooking up something fun and my boys look forward to it.

This coffee cake was an afterthought and I was super excited when it came together and tasted amazing! I had some leftover oatmeal and decided to make something with it instead of throwing it out.

I’ve mentioned before that I LOVE coffee cake. My mom used to make it all the time while I was growing up. It’s like eating dessert for breakfast! Nothing better than a slice of fresh-from-the-oven coffee cake with a glass of cold milk. It gives cookies a run for their money!

The best part about this coffee cake is how moist it is. The oatmeal really makes this cake soft and flavorful. Plus it has this delicious little nut topping that gives it a nice crunch. You can taste the oatmeal throughout the cake, too. I used Truvia instead of sugar and used half white whole wheat flour to give it more nutritional value.  If you like oatmeal and coffee cake, this is the perfect blend for you!Oatmeal Coffee Cake | delicious breakfast cake made using oatmeal for the moistest cake you'll ever eat!

    This cake looks and sounds really great, especially with the spices and pecans. I’ve started cooking more with coconut oil but have yet to make a baked good with it, so I’m looking forward to trying this. Pinned!

    Jen, Is the coconut oil an absolute must? I have someone with an alergy to coconut. Can I substitute vegetable oil instead? I love the look of this cake, and want to try it. Thanks.

      Absolutely! Go ahead and substitute vegetable or canola oil for the 1/3 cup and then you can use either a Tbsp. of butter or a Tbsp. of vegetable oil for the brown sugar topping. Let me know how it turns out! Thanks!

      Hi Angela – I think you could get away with not using the pecans. Just putting the brown sugar/coconut oil topping might taste delicious on its own. Let me know if you give it a try and how you like it! Thanks for stopping by!

    Hi there, the recipe looks great….but one question: when you say cooked oatmeal, what do you mean? and what do you cook it with? milk or water? do you add anything?
    Can you just add the oatmeal raw?

      Hi Margie! I just got your email but thought I would answer on here just in case others had the same question. You can either buy a box of instant packets or a container of oatmeal. Cook up one serving per directions on packet or container. I usually use water but you can use milk if you’d like too. The directions on my quick oats box says to cook 1 cup water with 1/2 cup dry oats and cook in the microwave for 1 minute 30 seconds. That gives you a little more than one cup. Just measure out one cup of that cooked oatmeal and use it in your recipe. Does that make sense? Please let me know if you have any other questions. Thanks!!

    Absolutely delicious! I replaced the batter coconut oil with Greek yogurt. Also, I baked 1/2 recipe for 20 minutes in a loaf pan. Perfect! My 8yo daughter had two slices already!

      Hi Patricia, coffee cake is merely a breakfast cake that goes with your coffee in the morning! It’s the perfect pairing for that morning cup! So, nope, no coffee in this cake. I hope you’ll give the recipe a try!

    I love oatmeal too and figure out ways to include some oats in just about every baked treat I make although I never thought to add in already cooked oatmeal, this I’ve got to try! Thanks so much for the great idea, this recipe looks so delicious.

    Hi Jen, I am kind of working on a budget and live very far out of town. I have everything to make this except coconut oil, and I really want to try this. I have had my eyes on a banana coffee cake lately but when I saw your recipe I thought it was definitely the healthier choice. So anyways, my question is…..do you think I could replace the coconut oil with mashed banana? Or at least partially and use a little vegetable oil or something. It always makes brownies very moist.

      Hi April! YES! You can definitely use canola or vegetable oil in place of the coconut oil! I really think you’ll love this coffee cake. I’m so excited you’re trying it!
