Cinnamon Roll Oatmeal Bars Ingredients
For the Base
• Rolled Oats – Provides base structure and chewiness; quick oats may work, but texture will differ.
• All-Purpose Flour – Adds stability and helps bind the bars; gluten-free flour can be used as a substitute.
• Brown Sugar (Base) – Sweetens and adds moisture; white sugar may be substituted, though flavor will change slightly.
• Melted Butter – Adds richness and moisture; coconut oil can be used as a dairy-free alternative.
• Salt – Balances sweetness and enhances flavor; leaving it out will dull the overall taste.
For the Filling
• Brown Sugar (Filling) – Enhances sweetness and cinnamon flavor; can be replaced with maple sugar for a different taste.
• Softened Butter – Provides flavor and moisture; use margarine for a vegan option.
• Ground Cinnamon – Key flavor component giving the bars their signature taste; for a different spice, use pumpkin spice mix.
For the Glaze
• Powdered Sugar – Used for the glaze to add sweetness and create a smooth topping; can use erythritol for a sugar-free version.
• Milk – Thins the glaze and adds creaminess; almond milk or any non-dairy milk can be used as a substitute.

How to Make Cinnamon Roll Oatmeal Bars
-
Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper to ensure easy removal later.
-
Combine rolled oats, all-purpose flour, 1/4 cup brown sugar, melted butter, and salt in a large mixing bowl. Stir well until all ingredients are fully mixed and crumbly.
-
Press the oat mixture firmly into the bottom of the prepared pan, creating an even base. This helps ensure everything holds together nicely while baking.
-
Cream together softened butter, 1/4 cup brown sugar, and ground cinnamon in a separate bowl until smooth and fluffy, which should take about 2-3 minutes.
-
Spread the cinnamon filling evenly over the oat base. Use a knife to swirl it gently if you prefer a marbled look.
-
Bake the bars in the preheated oven for 20-25 minutes. You’ll know they’re ready when the edges are golden brown and the center feels set to the touch.
-
Whisk together powdered sugar, milk, and vanilla extract in a separate bowl to create a smooth glaze. This should take just a minute or two.

Cinnamon Roll Oatmeal Bars Recipe FAQs
What type of oats should I use for Cinnamon Roll Oatmeal Bars?
I recommend using rolled oats for the best texture and structure, as they provide that lovely chewiness. Quick oats can be used, but the texture will be slightly different and less chewy.
How should I store my Cinnamon Roll Oatmeal Bars to keep them fresh?
Store your bars in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate them for up to a week or freeze for up to 2 months. Just ensure they’re well-sealed to prevent drying out.
Can I freeze Cinnamon Roll Oatmeal Bars? If so, how?
Absolutely! To freeze, let the bars cool completely, then place them in an airtight container or zip-top bag, stacking them with parchment paper between layers to prevent sticking. They can be frozen for up to 2 months. To enjoy, thaw them at room temperature or microwave for 10-15 seconds.
What can I do if my bars crumble when cutting them?
If your bars crumble, it might be a sign that the oat base wasn't pressed firmly enough into the pan. Ensure you compact the mixture well before baking. For future batches, also allow the bars to cool completely before cutting—this helps them hold together better!
Are there any allergy considerations for Cinnamon Roll Oatmeal Bars?
These bars contain gluten from the all-purpose flour, but you can easily make them gluten-free by substituting with a gluten-free flour blend. If you’re concerned about dairy, use coconut oil and margarine instead of butter to make them dairy-free or vegan-friendly.
Can pets eat Cinnamon Roll Oatmeal Bars?
While oats are safe for pets in moderation, these bars contain sugar and butter, which are not ideal for them. It’s best to avoid sharing these treats with your furry friends to keep them healthy and happy!
