Ingredients
Method
Step 1 – Brown the Butter
Place the butter in a saucepan over medium heat. Let it melt completely while stirring frequently. The butter will foam and then begin turning golden with small brown bits forming at the bottom. Once you notice a toasty aroma and deep amber color, remove the pan from the heat. Allow the butter to cool slightly for about 10 minutes before using.
Step 2 – Combine the Wet Ingredients
Pour the cooled brown butter into a large mixing bowl. Add the brown sugar and granulated sugar and stir until the mixture looks smooth and glossy. Whisk in the eggs and vanilla extract until the mixture becomes thick and shiny.
Step 3 – Mix the Dry Ingredients
In another bowl, combine the flour, baking powder, baking soda, cinnamon, cream of tartar, and salt. Stir everything together so the ingredients are evenly distributed. Gradually add the dry mixture into the butter mixture. Fold everything together gently with a spatula just until the dough forms. Avoid overmixing.
Step 4 – Bake the Bars
Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper, leaving extra paper hanging over the sides for easy removal later. Spread the thick dough evenly across the pan. Bake for 28–32 minutes, or until the edges turn golden and a toothpick inserted in the center comes out mostly clean. Let the bars cool completely before adding the glaze.
Step 5 – Prepare the Cinnamon Glaze
In a small bowl, whisk together powdered sugar, milk, vanilla extract, cinnamon, and a pinch of salt. If the glaze feels too thick, add a small splash of milk until it reaches a drizzle-friendly consistency. Once the bars have cooled, drizzle the glaze across the surface and allow it to set before slicing.
Notes
Serving Tips from My Kitchen
I like cutting these bars into smaller squares so they fit perfectly on dessert trays. They stay soft and hold their shape well, which makes them excellent for gatherings or sharing. They also travel well, so they’re perfect for picnics, potlucks, or bake sales. Pair them with fresh fruit or savory snacks and you’ve got an easy dessert spread. For extra neat slices, place the pan in the refrigerator for about 20 minutes before cutting. The chilled bars slice cleanly and look much sharper on a serving tray.Storage Tips
- Room temperature: Store in an airtight container for up to 3 days.
- Refrigerator: Keeps well for about 1 week when sealed tightly.
- Freezer: Wrap slices individually and freeze for up to 2 months.
