  • 9x9 Baking Pan
  • Mixing Bowls
  • Whisk
  • Measuring Cups and Spoons


  • 2 cups Flour spooned and leveled
  • 3 teaspoons Ground Cinnamon
  • 1 teaspoon Baking Powder
  • 1/4 teaspoon Baking Soda
  • 2 cups Brown Sugar packed
  • 2/3 cup Butter
  • 2 large Eggs
  • 2 teaspoons Vanilla
  • 1/4 cup Sugar
  • 1 tablespoon Butter melted


  • Preheat the oven to 350ºF and line a 9x9 baking pan or dish with aluminum foil leaving a 2-inch overhang on all sides. Spray the foil with cooking spray or grease.
  • In a medium bowl mix the flour, 2 teaspoons of cinnamon, the baking powder, and baking soda until fully combined, set aside.
  • In a large saucepan, melt the 2/3 cup of butter together with the brown sugar over medium heat, stirring occasionally until smooth. Remove the pan from the heat and let cool slightly.
  • Whisk the eggs and vanilla into the brown sugar and butter mixture until combined.
  • Pour the dry ingredients into the saucepan and whisk the ingredients together until a smooth batter forms (don't over mix the batter).
  • Spread the batter into the prepared baking pan and bake for 25 to 30 minutes (I typically bake mine until exactly 30 minutes), or until a toothpick inserted into the center comes out clean.
  • In a small bowl mix the remaining 1 teaspoon of cinnamon, sugar, and 1 tablespoon of melted butter and sprinkle on top of the bars.
  • Use the sides of the foil to lift the bars out of the baking pan and set on top of a wire rack to cool completely before slicing.


  • Use a large saucepan for melting the butter and brown sugar together so there's room enough in the pan to mix in the dry ingredients.
  • When mixing the dry ingredients into the brown sugar and butter mixture try not to overmix the batter. If you feel you're mixing the batter too much you can use a wooden spoon to fold the ingredients together instead.
  • When covering your baking pan with foil leaving a 2-inch overhang on the sides, which will make removing the squares extremely easy.
  • Change up the topping on these bars for something a little different. Try some cream cheese frosting or even buttercream. You can also drizzle on some melted chocolate or spread on a chocolate ganache.
  • These cinnamon bars will firm up as they cool so you'll want to let them cool completely before slicing into them (no judgment if you dig right in though). The bars on the edges will be slightly crispier than the ones in the middle that have an even gooey texture.
