The night before, sprinkle half the pecans in the bottom of a Bundt® pan that has been sprayed with non-stick vegetable spray.
Arrange dinner rolls on top of pecans; sprinkle with pudding mix.
Mix brown sugar and butter together; pour over rolls. Spread remaining pecans over top.
Place pan in a cold oven and let stand overnight to rise.
In the morning, remove pan from the oven and preheat to 325 degrees. Return pan to oven; bake for 30 minutes.
Turn pan upside-down onto a platter and serve.
