Step‑by‑Step Instructions for Cinnamon Roll Baked Oatmeal Squares
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven heats up, take an 8×8 inch baking dish and generously grease it with butter or non-stick spray. This ensures that your delicious Cinnamon Roll Baked Oatmeal Squares won’t stick, making it easier to serve them later.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together old-fashioned rolled oats, baking powder, ½ teaspoon of cinnamon, and a pinch of salt until the ingredients are evenly distributed. This combination builds the base for your squares, giving them structure and flavor. Set the bowl aside as you prepare to incorporate the wet ingredients.
Step 3: Mix Wet Ingredients
In a separate bowl, combine one egg (or a flax egg for a vegan option), milk of your choice, maple syrup, melted butter, and vanilla extract. Whisk these ingredients together until smooth and fully blended, creating a rich, creamy mixture. This will add moisture and flavor to your Cinnamon Roll Baked Oatmeal Squares.
Step 4: Combine Mixtures
Pour the wet mixture into the bowl with the dry ingredients. Gently stir everything together until just combined, making sure not to overmix. You want the oats to be moistened without losing their chewiness. This careful mixing will create the perfect texture and flavor for your squares.
Step 5: Create the Cinnamon Swirl
In a small bowl, prepare the cinnamon swirl by mixing the remaining melted butter, brown sugar, and 1 teaspoon of cinnamon together until a paste forms. This delightful mixture adds an irresistible sweetness and aroma to your Cinnamon Roll Baked Oatmeal Squares, creating the signature swirl effect.
Step 6: Layer and Swirl
Pour half of the oatmeal batter into the prepared baking dish and spread it evenly. Sprinkle half of the cinnamon swirl mixture over the batter. Next, pour the remaining batter on top, and finally, sprinkle with the rest of the cinnamon swirl. Use a knife to swirl the mixtures together gently, creating a beautiful marbled effect.
Step 7: Bake to Perfection
Place the dish into your preheated oven and bake for 25-30 minutes. Keep an eye on the squares—they should be golden brown around the edges, and the center should spring back lightly when touched. This baking process transforms your mixture into fluffy, decadent Cinnamon Roll Baked Oatmeal Squares.
Step 8: Cool & Serve
Once baked, remove the dish from the oven and let it cool for at least 10 minutes. This cooling time allows the squares to set properly, making them easier to slice. After cooling, cut them into squares and serve warm, enjoying the blend of flavors and textures that make this breakfast treat so delightful.

Cinnamon Roll Baked Oatmeal Squares Recipe FAQs

What if my oatmeal squares are too dense or dry?
Oh no, let’s troubleshoot! If your squares turn out dense or dry, it’s likely due to overmixing the batter or not measuring your ingredients accurately. Make sure to mix the wet and dry ingredients gently until just combined. If you find the batter too thick, you can add a dash more milk to achieve a smoother consistency. Never hesitate to adjust ingredients based on your taste and preferences!
