1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a slight overhang on two sides to lift the blondies out easily once baked.
2. In a small saucepan, melt the butter over medium heat. Keep stirring as it melts, watching for it to foam and then turn a lovely golden brown with a nutty aroma—this usually takes about 4-5 minutes. Be careful not to burn it!
3. Pour the browned butter into a large mixing bowl and let it cool for a few minutes. This step is key—too hot and it will cook the egg in the next step.
4. Add the brown sugar to the butter and whisk until the mixture is smooth and glossy.
5. Whisk in the egg and vanilla extract until fully combined.
6. Stir in the pumpkin puree until the batter is uniform and creamy. It might look a bit thick, but that’s perfect.
7. In a separate bowl, sift together the flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt.
8. Gradually fold the dry ingredients into the wet mixture, being careful not to overmix. If you’re adding nuts or chips, gently fold them in now.
9. Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
10. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs. The edges should be set and slightly golden.
11. Let the blondies cool completely in the pan on a wire rack before lifting them out and slicing into squares. This cooling step helps them set perfectly, just like Mama Lu always said, “Patience makes perfect.”

One kitchen story that sticks with me is the first time I browned butter on my own. I was nervous, thinking I’d ruin the whole batch. But as the scent filled the room, I knew I’d tapped into something special—the same kind of kitchen magic Mama Lu had taught me, just in a new form. That moment made these blondies even sweeter.
