Ingredients You’ll Need

1 cup unsalted butter, melted
1½ cups granulated sugar
½ cup brown sugar
2 large eggs
1 tbsp vanilla extract
2¾ cups all-purpose flour
½ tsp cream of tartar
½ tsp baking soda
½ tsp salt

Topping:

2 tbsp granulated sugar
1 tsp ground cinnamon

Step-by-Step Instructions

Preheat and Prepare Pan
- Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper, allowing a slight overhang for easy removal.

Mix the Wet Ingredients
- In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until the mixture is smooth and slightly thickened.
- Add in the eggs and vanilla extract. Mix until fully incorporated and glossy.

Add the Dry Ingredients
- In a separate bowl, combine the flour, cream of tartar, baking soda, and salt. Whisk to distribute evenly.
- Slowly stir the dry ingredients into the wet mixture. Mix just until no streaks of flour remain.

Spread and Sprinkle
- Spread the dough evenly into the prepared baking pan, smoothing the top with a spatula.
- In a small bowl, stir together the topping sugar and cinnamon. Sprinkle the mixture evenly over the dough surface.

Bake and Cool
- Bake for 25–30 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Allow the bars to cool completely in the pan before removing and slicing into squares or rectangles.

Serving and Storage Tips

Serve at room temperature: Their chewy texture is best enjoyed when not too cold.
Store in an airtight container: Bars will stay fresh and soft for up to 5 days.
Freeze for later: Wrap individual bars in plastic wrap and store in a freezer-safe bag or container for up to 2 months. Thaw at room temperature.

Elevate with extras: Drizzle with vanilla glaze or cream cheese frosting for a bakery-style finish.
Pair with drinks: Enjoy with coffee, chai tea, or warm apple cider for a cozy treat.

Helpful Notes

Don’t overbake: Slightly underbaking ensures a gooey, chewy center.
Add-ins for flair: Try mixing in butterscotch chips, raisins, or chopped nuts.

Clean slicing tip: Use a sharp knife dipped in hot water and wiped dry between cuts.
Make it festive: Add colored sugar sprinkles or a touch of nutmeg in the topping for seasonal flair.
Gluten-free option: Substitute a 1:1 gluten-free baking flour mix to accommodate dietary needs.
