20 large or 40 small squares
Preheat the oven to 350 degrees.
For the crust, beat the butter and granulated sugar in the bowl of an electric mixer, fitted with the paddle attachment, until light, approximately 3 minutes.
Add the eggs and the vanilla and mix well.
Sift together the flour, baking powder, and salt.
Mix the dry ingredients into the batter with the mixer on low speed until just combined.
Press the dough evenly into an ungreased 18 x 12 x 1 inch baking sheet, making an edge around the outside. It will be sticky, sprinkle the dough and your hands lightly with flour.
Bake for 15 minutes until the crust is set but not browned. Allow to cool.
For the topping, combine butter, honey, brown sugar, and zests in a large, heavy-bottomed saucepan.
Cook over low heat until the butter is melted, using a wooden spoon to stir. Raise the heat and boil for 3 minutes.
Remove from heat and stir in the heavy cream and pecans.
Pour over the crust, trying not to get the filling between the crust and the pan.
Bake for 25 to 30 minutes, until the filling is set. **NOTE**
Remove from the oven and allow to cool.
Wrap in plastic wrap and refrigerate until cold.
Cut into bars and serve. (at this time if you wish to make your bars a bit more decadent, dip or drizzle with warm chocolate.)
**NOTE** This filling may bubble over the edge. Place a large baking sheet or aluminum foil on a lower oven rack to catch the drips.
