Tips for the best results

Read through all the steps once before you start and measure out your ingredients first — it makes everything go more smoothly.
Preheat the oven fully and bake on the middle rack for the most even results.
Check for doneness a few minutes early — a toothpick in the center should come out with just a few moist crumbs.
Let it cool before slicing so it sets properly and holds its shape.
Store leftovers in an airtight container in the fridge and enjoy within a few days.

Variations & substitutions

Use a neutral oil or a plant-based spread in place of butter for a dairy-free version.
Brown sugar instead of white sugar adds a deeper, more caramel-like flavor.
