Step 1

Preheat oven to 350°F and grease a 9x13-inch baking dish with butter or nonstick spray.

Step 2

In a medium bowl, beat the butter and brown sugar with an electric mixer until smooth. Add eggs and beat again until smooth.

Step 3

Stir in buttermilk and vanilla, followed by the baking soda, salt, and flour. Beat until well mixed.

Step 4

Pour batter into prepared pan and bake until top feels set, 30-35 minutes.

Step 5

While cake bakes, prepare the topping:

Step 6

Stir together the melted butter and sugar. Add milk, salt, and pecans. The mixture will be thick but still pourable.

Step 7

Pour glaze over cake and gently spread out into an even layer. Return to oven for 10 minutes.

Step 8

Remove cake from oven. Topping will be very runny, but you can let it sit at room temperature for a few hours if you'd prefer glaze to be more set. Enjoy!
