Stir together first 11 ingredients in a large bowl.
Pour mixture evenly into 8 lightly greased 4-ounce ramekins or custard cups.
Place in a large roasting pan; add hot water to pan to depth of 1".
Bake, uncovered, at 325 for 55 minutes.
Meanwhile, melt butter in a large skillet over medium heat; add pecans and 1/2 cup sugar. Cook, stirring constantly, 6 minutes or until sugar is dissolved and mixture is just golden brown.
Pour onto a parchment paper-lined pan, spreading evenly. Cool completely; break into small pieces, and set aside.
Remove ramekins from water; cool slightly on wire racks. Cover and chill up to 24 hours, if desired.
To serve, top each custard with 1 1/2 tablespoons pecan topping.
