Preheat your oven to 325 degrees Fahrenheit. This ensures the pie bakes evenly and reaches the perfect consistency.
In a mixing bowl, combine 1 cup brown sugar and 1/2 cup dark Karo syrup. Using a whisk, mix them together until well blended. You’ll want to ensure there are no lumps in the sugar.
Melt 1 stick butter in a small saucepan or in the microwave. Once melted, add it to the mixing bowl with the sugar and syrup. Stir well until all the sugar is dissolved, creating a smooth mixture.
Add 4 eggs one at a time, mixing thoroughly after each addition. This will help incorporate the eggs evenly into the filling.
Stir in 1 teaspoon vanilla, mixing until well combined. The vanilla will add a delightful aroma and enhance the flavors.
Prepare your 9-inch pie shell by placing it in a pie plate. If you’re using a frozen crust, make sure it’s thawed before adding the filling.
Pour the filling mixture into the prepared pie shell. Use a spatula to ensure it’s evenly distributed.
Carefully arrange 2 cups pecan halves on top of the filling. You can create a beautiful pattern or simply scatter them across the surface; either way, they’ll provide a lovely crunch.
Bake in the preheated oven for 50 minutes. You can check for doneness by inserting a knife into the center; if it comes out clean, your pie is ready!
Once baked, remove the pie from the oven and let it cool to room temperature. This will help the filling set properly before you slice into it.
