Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
- In a medium bowl, whisk together flour, baking soda, cream of tartar, salt, and nutmeg if desired for 1-2 minutes.
- In a large bowl, beat softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
- Add eggs one at a time, mixing well after each, then stir in vanilla extract.
- Gradually mix dry ingredients into wet ingredients until just combined, avoiding overmixing.
- Fold in 2 tablespoons of the cinnamon sugar into the dough.
- Spread the batter evenly in the prepared pan.
- Sprinkle remaining cinnamon sugar generously over the top.
- Bake for 25-28 minutes until golden brown and a toothpick comes out with moist crumbs.
- Cool completely in the pan on a wire rack for about 30 minutes before slicing.

Notes
For best texture, do not overmix and allow to cool completely before slicing to prevent crumbly pieces.
