- Preheat oven to 350 degrees. Grease a 9×13 baking pan.
- For the crust, blend confectioners sugar and flour together in a food processor. Gradually add 16 tablespoons of softened butter and vanilla extract using pulse mode. Mix until just combined as over-processing will make a tough crust.
- Pat the crust into the prepared baking pan. Bake for 25 minutes, until golden brown. Remove from oven and cool on a rack.
- For the topping, mix melted butter, honey, cream, orange zest, and brown sugar together. Stir in pecans. Spread over prepared crust. Return to oven and bake for 25 minutes. Cool completely before cutting into squares.
