Instructions
Prep the pan: Preheat oven to 350°F (175°C). Line a 9x13-inch metal baking pan with parchment paper.
Make cinnamon sugar: In a small bowl, stir together the sugar and cinnamon. Set aside.
Mix the wet ingredients: In a large mixing bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth. Add eggs and vanilla; whisk until glossy and fully combined.
Stir in dry ingredients: Add flour, baking powder, cream of tartar, and salt. Fold until a thick dough forms.
Assemble: Spread the dough evenly into the prepared pan. Sprinkle cinnamon sugar generously over the top.
Bake: Bake for 25–30 minutes, or until edges are golden brown and a toothpick inserted into the center comes out with moist crumbs.
Cool & slice: Let cool completely in the pan, then lift out and slice into bars.
Notes
Disclaimer: I bake by weight for accuracy. Cup measurements are approximate and may vary depending on how you scoop. Audrey's tip: If you like a gooier center, pull them at the 25-minute mark and let them cool in the pan. Prefer them firmer and cookie-like? Give them the full 30. Either way—don’t skip the cream of tartar. It gives that signature snickerdoodle tang!Storage: These bars keep well in an airtight container at room temperature for 3–4 days. For longer storage, refrigerate for up to a week or freeze for up to 2 months. To freeze, wrap the bars tightly in plastic wrap and place them in a freezer-safe bag. Thaw at room temperature before serving.
