Method
Preparation
- Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
- In a large bowl, combine the melted butter, brown sugar, and granulated sugar. Mix until smooth and shiny, about 2 minutes.
- Add the eggs and vanilla extract, stirring until fully incorporated and glossy.
- In another bowl, whisk together the flour, baking powder, salt, and cinnamon.
- Gradually add the dry mixture to the wet ingredients, mixing gently until just combined. A few floury streaks are okay.
- Pour the batter into the prepared baking dish and spread evenly.
- Mix the additional sugar with a pinch of cinnamon and sprinkle generously over the batter.
Baking
- Bake for 25-30 minutes. Check doneness with a toothpick inserted in the center.
- Allow to cool in the pan for about 10-15 minutes before slicing into squares.
Notes
For a richer flavor, consider browning the butter before mixing. Store in an airtight container for up to 3 days, or freeze for up to 3 months.
