NYT: Much like its author, this recipe is a no-fuss classic. It calls for just 1/4 cup of flour, which yields an incredibly rich and gooey brownie, and it's super easy to make. So easy, in fact, that baking a batch of these might just become part of your weekend routine.

• 1/2 cup cocoa
• 1 stick butter
• 2 eggs
• 1 cup sugar
• 1/4 cup flour
• 1 cup broken-up walnuts or pecans
• 1 teaspoon vanilla
• pinch of salt

1. Heat oven to 325 degrees.
2. Melt butter in saucepan with cocoa and stir until smooth. Remove from heat and allow to cool for a few minutes, then transfer to a large bowl. Whisk in eggs, one at a time. Stir in vanilla.
3. In a separate bowl, combine sugar, flour, nuts and salt. Add to the cocoa-butter mixture. Stir until just combined.
4. Pour into a greased 8 x 8-inch-square pan. Bake 30 to 35 minutes. Do not overbake; the brownies should be gooey. Let cool, then cut into bars.

• Original letter to the editor: Katherine Hepburn's Brownies
• “This has been my go-to brownie recipe for 30 years. In the ’80s, an acquaintance in Germany to whom I brought some of the brownies, and who considered herself a great cook, asked for the recipe but was never able to get it to work. She kept asking me what she was doing wrong and I was never able to solve her problem. Eventually, she moved to the U.S. and stole my husband!” (Sydne Newberry's comment, one of the best recipe comments ever.)
