Yield: 30 bars
Prep Time: 25 min + cooling time
Cook Time: 35 min
1/2 cup (1 stick) unsalted butter, at room temperature
1/4 cup granulated white sugar
1 large egg yolk
1 1/2 cups all-purpose flour
1/8 teaspoon salt
1/2 cup pure maple syrup
1/3 cup packed light brown sugar
1/4 cup heavy whipping cream
3 tablespoons unsalted butter
1/2 teaspoon pure vanilla extract
1 1/2 cups finely chopped pecans
1. To prepare crust: Preheat oven to 350 degrees F. Butter 9x9x2-inch metal cake pan. Using electric mixer, beat butter, sugar and egg yolk in a bowl to blend. Add flour and salt; beat until moist clumps form. Gather dough together. Press dough over bottom and 1/2-inch up sides of pan. Bake crust until golden, about 20 minutes. Cool.
2. To prepare filling: Combine first 4 ingredients in medium saucepan. Bring to boil, stirring until butter melts and mixture is smooth. Boil filling 30 seconds. Remove from heat; mix in vanilla, then nuts.
3. Pour hot filling into crust. Bake bars until filling is bubbling in center, about 15 minutes. Cool bars completely in pan on rack (filling will become firm). Chill at least 1 hour and up to 2 hours. Cut into small-sized bars.
*These bars may be prepared up to three days ahead.
