Brown Sugar Pecan Pie Brownies

1. Preheat the oven to 350° F. Line a 9x9 inch square pan with parchment paper.
2. In the microwave, melt together the butter and 3/4 cup chocolate chips. Stir in the sugar, and vanilla.
3. In a bowl whisk the eggs until bubbly on top, 1 minute. Whisk the eggs into the chocolate mixture, whisking until the chocolate turns thick and glossy. Stir in the flour, cocoa powder, baking powder, and 1/4 cup chocolate chips, until just combined. Spread the mixture into the prepared pan. Bake 15-20 minutes, until the brownies are just set (I bake mine exactly 15 minutes).
4. Arrange the chocolate pieces over the brownie. 
4. Meanwhile, make the pie layer. Whisk together the brown sugar and 2 eggs, and 1 egg yolk until, pale in color, about 3-4 minutes. Add the maple syrup and cream. Whisk in the melted butter and vanilla. Fold in the pecans. Gently pour the filling over the pre-baked brownie. 
5. Bake for 30 to 35 minutes, until the brownies are just barely set on top. If your pecan layer is still wiggly in the center, continue baking another 20-25 minutes, until the center is melty set. The longer you bake, the more set your brownie will be. Remove from the oven and let cool. Slice into bars and enjoy the yumminess.
