The Simple Ingredients That Make Magic
What I adore about this baked oats cake is how ordinary ingredients transform into something extraordinary. Here’s exactly what you’ll need (and why each one matters):
- 1 cup rolled oats (blended into flour): The star! Old-fashioned oats give the best texture—quick oats can get gummy.
- 1 ripe banana (the spottier, the better!): Nature’s perfect sweetener and binder. No mushy banana? Swap 1/4 cup applesauce.
- 1 egg (room temp): Gives structure. For vegan, use a flax egg (1 tbsp ground flax + 3 tbsp water).
- 1/2 cup milk (any kind): I use almond, but dairy or oat milk work great too.
- 1 tbsp honey or maple syrup: Just enough sweetness. Skip if your banana is super ripe!
- 1 tsp vanilla extract: That cozy bakery aroma? This is the secret.
- 1 tsp baking powder: Lifts our cake to fluffy perfection.
- 1/4 tsp cinnamon + pinch salt: Balances flavors like a dream.
See? Nothing weird—just simple, wholesome ingredients that probably live in your kitchen right now.

How to Make Baked Oats Blended Oatmeal Cake
Alright, let’s get baking! This baked oats cake comes together so easily—just three simple steps between you and breakfast bliss. Promise it’s foolproof (even if you’re usually more of a microwave breakfast person). Here’s exactly how I make it, with all my little tricks for perfect results every time:
Step 1: Prepare the Oat Flour
First, grab your blender or food processor—I use my trusty old Nutribullet. Dump in the rolled oats and pulse until they’re as fine as regular flour (about 30 seconds). You’ll know it’s ready when it looks like powdery snow! Pro tip: blend a big batch of oat flour ahead to save time later.
Step 2: Blend the Batter
Now the fun part—keep that blender going and add everything else! Banana first (peeled, obviously—learned that the hard way!), then egg, milk, honey, vanilla, baking powder, cinnamon and salt. Blend until smooth like pancake batter, scraping down sides if needed. Oh, that smell? Pure breakfast magic already.
Step 3: Bake to Perfection
Pour your batter into a greased 8×8 dish—it should spread itself evenly. Bake at 350°F for 20-25 minutes. Start checking at 20 minutes—a toothpick should come out clean, but the top should still feel springy. Let it cool 5 minutes (tough, I know!) before slicing. That’s it—cake for breakfast achieved!

Tips for the Best Baked Oats Blended Oatmeal Cake
After making this baked oats cake more times than I can count (okay, maybe 20 times last month), I’ve picked up some game-changing tricks:
- Texture tweak: Love it extra fluffy? Add an extra 1/4 tsp baking powder. Prefer dense? Use less milk.
- No blender? Mash banana super fine and whisk by hand—just soak oats in milk for 10 minutes first.
- Golden top hack: Broil for 1-2 minutes at the end (watch closely!) for bakery-worthy crispiness.
- Overbaking alert: Pull it out when edges just brown—center keeps cooking as it cools!
- Flavor boost: Stir in lemon zest or almond extract for a fun twist.
Trust me, once you nail these little details, you’ll never look at oatmeal the same way again!
Variations of Baked Oats Blended Oatmeal Cake
The best part about this baked oats cake? It’s basically a blank canvas waiting for your personal touch! Here are my favorite ways to jazz it up—because who says breakfast can’t be fun?
- Berry bliss: Fold in 1/2 cup fresh blueberries or raspberries before baking (frozen work too—just don’t thaw!).
- Chocolate fix: Stir in 2 tbsp cocoa powder + 1/4 cup chocolate chips for dessert-for-breakfast vibes.
- Nutty crunch: Top with chopped walnuts or pecans before baking—that toasty crunch is EVERYTHING.
- Tropical twist: Swap banana for 1/2 cup mashed mango, then add shredded coconut on top.
- PB&J style: Swirl in 2 tbsp peanut butter and dollop strawberry jam before baking.
See? One recipe, endless possibilities. Your mornings just got way more exciting!

Serving and Storing Baked Oats Blended Oatmeal Cake
Okay, let’s talk about the best part—eating this glorious baked oats cake! I love slicing it warm right out of the oven (that cinnamon smell—wow!) and piling on toppings. A dollop of Greek yogurt with honey drizzle? Perfection. My husband goes nuts for peanut butter and banana slices on top. Kids adore it with a sprinkle of mini chocolate chips that melt into gooey pockets.
For storing, just let it cool completely, then tuck it into an airtight container. It stays fresh at room temp for 2 days, or pop it in the fridge for up to 5 days. Pro tip: freeze individual slices wrapped in parchment—30 seconds in the microwave brings them back to life for rushed mornings. Honestly? I’ve caught myself eating it cold straight from the fridge at midnight… no judgement here!

Frequently Asked Questions
Can I make this baked oats cake vegan?
Absolutely! Just swap the egg for a flax egg (1 tbsp ground flax + 3 tbsp water, let sit 5 minutes) and use plant-based milk. I’ve made it this way for my vegan sister-in-law—she couldn’t tell the difference!
My cake turned out gummy—what went wrong?
Oh no! Usually this means either the oats weren’t blended fine enough (they should look like flour) or the batter was overmixed. Next time, pulse the oats extra well and stop blending as soon as everything’s combined.
Can I use steel-cut oats instead?
I wouldn’t recommend it—steel-cut oats are too tough for blending into flour. Stick with old-fashioned rolled oats for that perfect cakey texture. Quick oats work in a pinch, but the texture will be slightly denser.
How do I know when it’s done baking?
The edges should pull away slightly from the pan, and a toothpick inserted in the center should come out clean (maybe with a crumb or two). If it jiggles like pudding, give it 2 more minutes!
Can I double this recipe?
Yes! Just use a 9×13 pan instead and add 5-10 minutes to the bake time. My family loves when I make a big batch—the leftovers disappear fast!
