How to Make Cinnamon Roll Baked Oatmeal Squares
-
Preheat the oven to 350°F. Grease an 8×8-inch baking pan with cooking spray or butter to ensure easy removal of the squares later.
-
Combine the rolled oats, baking powder, ground cinnamon, and salt in a mixing bowl. Stir well to mix the dry ingredients evenly, as this will form the base of your oatmeal squares.
-
Whisk together the egg, milk, maple syrup or honey, melted butter or coconut oil, and vanilla extract in a separate bowl. This mixture will provide the moisture and flavor needed for your oatmeal squares.
-
Pour the wet mixture into the bowl of dry ingredients and stir until everything is well combined. The batter should be thick and slightly sticky, filled with warm cinnamon aroma.
-
For the Cinnamon Swirl: In a separate bowl, mix the melted butter or coconut oil, brown sugar, and additional ground cinnamon until crumbly. This will create the sweet swirl that gives your squares that perfect cinnamon roll taste.
-
Spread the oatmeal mixture evenly into the prepared pan, then gently swirl the cinnamon mixture into the top using a knife or spatula. Be careful not to overmix—just a few swirls is enough to give that beautiful marbled effect.
-
Bake in the preheated oven for about 25-30 minutes, or until the squares are set and lightly golden. Test for doneness by inserting a toothpick; it should come out mostly clean when they’re ready.
-
Cool the oatmeal squares in the pan for about 10 minutes before slicing them into squares and serving. This cooling period makes them easier to cut and enjoy.
Optional: Drizzle with additional maple syrup for extra sweetness.

Expert Tips for Cinnamon Roll Baked Oatmeal Squares

Cinnamon Roll Baked Oatmeal Squares Recipe FAQs
How do I choose the right oats for this recipe?
Absolutely! For the best results, opt for old-fashioned rolled oats. They provide the perfect chewy texture and hold their shape well. Avoid using instant oats, as they can become mushy and won’t contribute to the desired structure of your Cinnamon Roll Baked Oatmeal Squares.
How should I store Cinnamon Roll Baked Oatmeal Squares?
I recommend storing leftovers in an airtight container at room temperature for up to 3 days. For longer preservation, you can refrigerate them for up to 1 week. Be sure to keep them wrapped to prevent drying out, especially in the fridge!
Can I freeze my Cinnamon Roll Baked Oatmeal Squares?
Yes, they’re great for freezing! To freeze, individually wrap the squares in plastic wrap and then place them in a sealed freezer bag. They can last in the freezer for up to 3 months. When you’re ready to enjoy them, simply thaw in the refrigerator overnight and reheat in the microwave or oven.
What should I do if my oatmeal squares don’t set properly?
If your Cinnamon Roll Baked Oatmeal Squares are not setting properly, it may be due to underbaking. Make sure to test with a toothpick around the 25-minute mark; it should come out mostly clean. If needed, bake an additional 5 minutes, checking periodically. Having a reliable oven temperature is crucial too, so consider using an oven thermometer for accuracy!
Are there any dietary considerations to keep in mind?
Very much so! This recipe can easily be adapted for various dietary needs. For a vegan option, substitute the egg with a flaxseed egg (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water, let sit for 5 minutes) and use plant-based milk. Also, replace honey with agave nectar if you’re keeping things plant-based. If there are nut allergies in the family, make sure to skip any optional add-ins like nuts.
How can I enhance the flavor of my squares?
To take your Cinnamon Roll Baked Oatmeal Squares up a notch, consider adding a touch of nutmeg along with the cinnamon for added warmth. You can also include mix-ins like raisins or chopped pecans for extra flavor and texture. The more, the merrier!
