Heat oven to 350°F. Spread pecans in ungreased shallow pan. Bake uncovered 6 to 10 minutes, stirring occasionally, until light brown. Cool completely.
Lightly grease 11-inch tart pan with removable bottom with shortening or cooking spray. In food processor, place flour, powdered sugar and 3/4 cup butter. Cover; process with on-and-off pulses until consistency of coarse meal. Pat mixture evenly on bottom and up side of pan. Bake 20 minutes or until edges are lightly browned. Cool 15 minutes.
Meanwhile, in 3-quart saucepan, heat brown sugar, honey, 2/3 cup butter and the whipping cream to boiling over medium-high heat. Stir in toasted pecans; spoon hot filling into partially baked crust. Bake 25 to 30 minutes or until golden and bubbly. Cool completely on cooling rack, about 30 minutes.
