- 1/2 cup (60g) All-Purpose Flour
- 1/4 cup (50g) Brown Sugar (base)
- 1/4 cup (50g) Brown Sugar (filling)
- 1/4 cup (57g) Melted Butter (base)
- 1/4 cup (57g) Softened Butter (filling)
- 1/4 tsp (1.5g) Salt
- 1 tbsp (8g) Ground Cinnamon
- 1/2 cup (60g) Powdered Sugar
- 1-2 tbsp (15-30ml) Milk
- 1/4 tsp (1.25ml) Vanilla Extract
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Line a square baking pan with parchment paper or lightly grease it.
- Step 2: In a large bowl, combine the rolled oats, all-purpose flour, 1/4 cup brown sugar (base), salt, and half of the ground cinnamon. Stir in the melted butter until the mixture is crumbly.
- Step 3: Press about two-thirds of this oat mixture firmly into the bottom of the prepared pan to form the base layer.
- Step 4: In a separate bowl, mix the softened butter, remaining 1/4 cup brown sugar (filling), and the remaining cinnamon until smooth and well combined. Spread this cinnamon filling evenly over the oat base.
- Step 5: Crumble the remaining oat mixture over the cinnamon layer to create a crumb topping.
- Step 6: Bake for 25-30 minutes or until the top is golden brown. Remove from oven and let cool completely in the pan.
- Step 7: While the bars are cooling, whisk together the powdered sugar, milk (start with 1 tablespoon), and vanilla extract to make the glaze. Add more milk if needed to achieve a drizzle-able consistency.
- Step 8: Drizzle the glaze over the cooled bars. Cut into squares and serve.
Tips & Variations
- For nutty flavor and crunch, add 1/4 cup chopped walnuts or pecans into the oat mixture.
- Use maple syrup instead of powdered sugar glaze for a naturally sweet topping.
- Press the oat base firmly to ensure the bars hold together well after baking.
- Make it vegan by substituting butter with coconut oil and using a plant-based milk for the glaze.
Storage
Store the bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week. Reheat gently in the microwave for 10-15 seconds if you prefer them warm before serving.

FAQs
Can I use quick oats instead of rolled oats?
Quick oats can be used, but the bars will be softer and less chewy since quick oats absorb liquid differently. Rolled oats provide better texture for this recipe.
Can I make these bars gluten-free?
Yes, substitute the all-purpose flour with a gluten-free flour blend and ensure your oats are certified gluten-free to keep the bars safe for gluten-sensitive diets.

- 1/4 cup (57g) Melted Butter

Glaze
- 1/2 cup (60g) Powdered Sugar
- 1–2 tbsp (15-30ml) Milk
- 1/4 tsp (1.25ml) Vanilla Extract
Instructions
- Prepare the oven and pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it to prevent sticking.
- Make the base mixture: In a large mixing bowl, combine the rolled oats, all-purpose flour, 1/4 cup brown sugar, melted butter, and salt. Stir until all ingredients are thoroughly mixed into a crumbly dough.
- Press base into pan: Transfer about two-thirds of the oat mixture into the prepared baking pan. Using the back of a spoon or your hands, press it firmly and evenly across the bottom to form the base layer.
- Prepare the cinnamon filling: In a separate bowl, mix the softened butter, 1/4 cup brown sugar, and ground cinnamon until smooth and well combined to create the cinnamon filling.
- Spread the filling: Evenly spread the cinnamon-sugar filling over the pressed oat base layer in the pan.
- Add the topping: Crumble the remaining oat mixture over the cinnamon filling, sprinkling it evenly to cover the filling layer.
- Bake the bars: Place the pan in the preheated oven and bake for approximately 25-30 minutes, or until the top is golden brown and the bars are set.
- Prepare the glaze: While the bars bake, whisk together the powdered sugar, milk, and vanilla extract in a small bowl until smooth. Adjust the milk quantity to reach desired glaze consistency.
- Cool and glaze: Allow the bars to cool completely in the pan on a wire rack. Once cooled, drizzle the prepared glaze evenly over the bars.
- Serve: Cut into squares and serve. Store any leftovers in an airtight container at room temperature for up to 3 days.
Notes
- For a richer flavor, you can use brown butter instead of regular melted butter in the base.
- Adjust the amount of cinnamon in the filling to your preference if you want it spicier or milder.
- Add chopped nuts such as pecans or walnuts to the topping for an extra crunch.
- If you prefer a dairy-free version, substitute butter with coconut oil and use a non-dairy milk for the glaze.
- Make sure bars are fully cooled before glazing to prevent the glaze from melting and sliding off.
