Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. In a large bowl, cream 10 tbsp softened unsalted butter with 1/2 cup granulated sugar until light and fluffy, about 3 minutes.
  2. Step 2: Beat in 3 tbsp buttermilk and 1/4 tsp salt until combined, then stir in 1 1/2 cups all-purpose flour until mixture forms a soft dough.
  3. Step 3: Press dough evenly into a greased 9x13-inch baking pan to form the crust; bake for 15 minutes until edges are lightly golden.
  4. Step 4: Meanwhile, whisk together 2 large eggs, 1 cup light corn syrup, 3/4 cup packed brown sugar, and 1 tsp vanilla extract in a medium bowl until smooth.
  5. Step 5: Stir 1 1/2 cups chopped pecans into the egg mixture, then pour evenly over the pre-baked crust.
  6. Step 6: Return pan to oven and bake for an additional 30-35 minutes, or until the filling is set and golden brown.
  7. Step 7: Cool completely on a wire rack before cutting into bars to serve.
