Ingredients:

  • 1 cup (225g) unsalted butter, browned and cooled slightly
  • 2 cups (400g) granulated sugar
  • 3 large eggs (room temperature)
  • 1 tsp (5ml) pure vanilla extract
  • 2 ½ cups (310g) all-purpose flour
  • 1 tbsp (12g) baking powder
  • ½ tsp (3g) salt
  • 1 cup (240g) full-fat sour cream
  • ½ cup (120ml) whole milk
  • 1 cup (115g) chopped pecans, toasted
  • 1 cup (225g) unsalted butter, softened
  • 3 ½ cups (420g) powdered sugar
  • ¼ cup (60ml) maple syrup (grade A)
  • 2 tbsp (30ml) heavy cream
  • 1 tsp (5ml) vanilla extract
  • ½ cup (55g) finely chopped toasted pecans

Instructions:

  1. Brown the butter in a skillet over medium heat, whisking constantly until it foams and turns a golden mahogany color with a nutty aroma. Immediately remove from heat to prevent burning.
  2. Toast the pecans in a dry pan for 3-5 minutes until fragrant and slightly darker.
  3. Cream the browned butter and granulated sugar until pale and fluffy.
  4. Beat in eggs one at a time, followed by the vanilla.
  5. In a separate bowl, whisk together flour, baking powder, and salt.
  6. Alternately add the dry ingredients and the sour cream/milk mixture to the butter mixture, beginning and ending with the flour.
  7. Gently fold in the toasted pecans by hand.
  8. Divide batter evenly between two greased and parchment-lined 9-inch round cake pans.
  9. Bake at 350°F (175°C) for 28–32 minutes until the edges pull away from the pan and a toothpick inserted into the center comes out with a few moist crumbs.
  10. Cool in pans for 10 minutes before transferring to a wire rack.
  11. Beat softened butter until smooth, then gradually add powdered sugar, maple syrup, heavy cream, and vanilla.
  12. Whip on high for 2 minutes until airy.
  13. Spread a thick layer of frosting between the cake rounds and cover the top and sides.
  14. Press remaining chopped pecans into the sides for a polished look.
