Looking for a nutritious way to start (or end) your day? This Gluten-free Oatmeal Cake is a super easy recipe that’s loaded with whole grains and lots of flavor and can be easily made vegan too.
It’s a healthy treat that your whole family is sure to love!
Breakfast is a tough meal of the day for families on the go who are trying to be healthy. It’s easy to lean on convenience foods so that everyone can grab something fast when they’re headed out the door, and that can mean some not so good decisions, you know?
Breakfast When I Was Growing Up
When I was little, we had a lot of those “not so good for you” type breakfasts.
Now granted, convenience foods were all the rage. Not many people were talking about whole grains or organic, or gluten-free or non GMO for that matter.
And as far as I remember, no one was talking about these “foods” being bad for you.
Some of the breakfast “foods” that I remember us having were:
Thomas’® English Muffins
Thomas’ Corn Toast-R-Cakes®
Homemade Cinnamon Toast (made with margarine and white bread and granulated white sugar–yikes!)
Ka-Boom® Cereal (my sister’s favorite)
Cinnamon Toast Crunch
Cream of Wheat
Get the idea :)?
I have distinct memories of riding to school in the car eating my cinnamon toast, munching on the sweet crunchy moistness that it was. Yum.
Now that I’ve woken up to how important it is to have real food, things have changed. Oh how they have changed.
The Move to Healthier Breakfasts
Since we’ve become more whole foods focused as a family, we’ve changed what we’ve had on our breakfast table.
Now, I never did serve PopTarts, or the above-mentioned “Toast-R-Cakes®” to my family, but regardless, we have had to make some changes.
When I was first married, we would eat pre-sweetened yogurt, and sometimes “healthier” boxed cereals, but as time went on, even those went by the wayside.
We ditched processed cereals and the yogurts that have a lot more sugar than you think. Really–check the label if you don’t believe me.
Now, over the years we have moved to eating lower carbs, we still do enjoy grains now and then, but when we do, they are always whole grain and gluten-free.
This Whole-grain, Gluten-free Oatmeal Cake fits the bill and has been a favorite in our home for a long time.
A Healthier Breakfast Option
Now, truth is, we are a little unconventional around here and have been known to have some unusual breakfasts. Like this Chocolate Chia Pudding, this Bean Fudge, or Homemade Protein Bars or Almond Joy® Bars for breakfast. Actually those Almond Joy Bars are amazing for breakfast–tons of healthy fats to get you going and keep you satisfied.
The way I see it – if it’s healthy, you can have it for breakfast, right? Even if it’s fudge.
Why not last dinner’s leftovers, in fact?
This Oatmeal Cake Recipe is, of course, a little more of a conventional breakfast food.
The Origin of this Cake
Our Baked Oatmeal Cake obsession all started when our dear friend, Beckie, shared some baked oatmeal with us at her home one night after a homeschooling family gathering. I’d heard of baked oatmeal, but had never made it nor tried it.
Well, my kids gobbled it up and….when gobbling like that happens, I go on a mission. This time on a quest for the best Baked Oatmeal recipe that I could find.
I came home with Becky’s recipe in hand and poked around on the internet a bit. I found a few recipes that intrigued me, but I ended up making a combination of my friend’s recipe and this one from Baked Bree.
The resulting success story is what you see pictured above.
A Kitchen Mistake Gone Right
The funny thing about this recipe is it basically was a mistake. Remember I mentioned that Becky’s recipe for for baked oatmeal?
Well, this recipe became a “cake” by mistake.
I knew it was important to soak grains (especially oats) and so when I set out to try out my version of the cake, I set the oats out to soak overnight.
The next day ended up being a flurry of too many things to do and so I didn’t get around to baking the cake until about 24 hours later. The result? A delicious not-too-sweet-at-all cake that is so light, you won’t believe that it is made from whole rolled oats.
In fact, when I took the 24-hour-soaked version over to Becky’s house for her to try, she said, “You added flour to this, didn’t you?”
Nope–the oats just turned out that way. Amazing. See how much soaking your grains can change the grains themselves?
Side note–for another “mistake turned family favorite, see my post on Chaat Masala.)
You could definitely make this dish the Baked Oatmeal Way, but I will most likely work on that to perfect it into another recipe.
But if you like experimenting, for a more Baked Oatmeal-ish recipe, simply soak the oats overnight only. Or you could simply not soak them at all. The top will be more like a cake, but the bottom of the dish will be more dense and like thick oatmeal on the bottom.
Either way–oatmeal yumminess.
The photos in this post are of the “soaked for 24 hour” option.
Don’t know about soaking grains? I never had heard of this until a few years ago and I didn’t really understand. The basic reason is that grains (and especially oats) contain phytic acid and other anti-nutrients that make digestion difficult. You can read more about this in my post on how and why to soak grains.
We like this recipe both ways, but I personally think the cake version is a bit nicer.
If you try it both ways, I would love to hear what you think!
Either way, this cake tastes special–especially topped with whipped cream or yogurt–and lots of fruit.
- Topping Options: I make this regularly with walnuts and dried apples from our dehydrator. So many combinations are possible. Bananas and walnuts, fresh apples and pecans. For the cake in these photos we used berries and walnuts. We even once just blended shredded coconut (about 1/3 cup) into the batter and sprinkled both cinnamon sugar and extra coconut on top. Mmmmmm……
- Milk Options: Use any type of milk you prefer. I recommend healthy raw milk if you use dairy. Otherwise, any non-dairy alternative will work great like Almond Milk, Coconut Milk, or Rice Milk, etc. Here is a great organic store-bought coconut milk.
- Bake In Bulk: As with any tried and true recipe, I recommend Baking in Bulk to save time and money. I’ve made the mistake of baking new recipes in bulk before (and then I end up with way too much of something we may not like). But now I’m getting better at “new recipe restraint” and so now I just bulk bake with the recipes that we love. I typically mix up and soak 4 batches of this cake at time. Make a bunch and freeze for on-the-go breakfasts or snacks anytime you need them.
- Gluten-free Oats: If necessary, use gluten-free oats. Here is a great brand. I’ve heard that the GF Harvest Company’s oats are very reliably gluten-free and they test for glyphosate too!
- Oil / Fat Options: You can use any other healthy fat for the coconut oil, or use applesauce for a fat-free / Trim Healthy Mama (THM:E) menu option.
- Sweetener Options: Although xylitol is a good candida-friendly sweetener, organic erythritol is as well. Or sub a liquid sweetener using my guidelines in Substituting Sweeteners. You can use an additional 1/3 cup of a healthy granulated sweetener instead of stevia. If using stevia, here is a great brand of stevia scoops. Also, see How to Use Stevia for some tips on stevia.
- Egg Alternatives: This is the egg substitute we used for years. See my Powdered Egg Substitute for a homemade option. This cake turns out great with either option.
- Baking Powder Option: If you would like to make your own baking powder, or need a corn-free or grain-free option, see this Grain-free Baking Powder.
- Cinnamon Sugar Substitute: See this Healthier Cinnamon Sugar for a homemade cinnamon sugar alternative.
- Soaking Notes – as you can see in my post on soaking grains, typically an acidic medium is recommended, but there are mixed thoughts on this. You could add a splash of apple cider vinegar to the oats before soaking.
