These chewy cinnamon oatmeal squares are a delightful twist on classic oatmeal bars, perfect for a snack or dessert.
Preheat your oven to 350°F (175°C).
Always preheat your oven to ensure even baking.
In a mixing bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.
Ensure the butter is at room temperature for easier mixing.
Add the egg and vanilla extract to the creamed mixture and mix until well combined.
Crack the egg into a separate bowl first to avoid shell pieces.
In a separate bowl, whisk together the flour, cinnamon, baking soda, and salt.
Sifting the dry ingredients can help avoid lumps.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Do not overmix to keep the bars tender.
Fold in the oats until evenly distributed.
Use a spatula to ensure the oats are evenly mixed.
Press the mixture into an ungreased 9x13-inch baking dish, spreading it evenly.
Use the back of a spoon to smooth the surface.
Bake in the preheated oven for 30-35 minutes, or until golden brown.
Check for doneness by inserting a toothpick; it should come out clean.
Allow the bars to cool completely in the pan before cutting into squares.
Cooling completely ensures clean cuts and better texture.
