Preheat the oven to 325°F/160°C, and lightly spray a 9x13-inch pan with cooking spray. Set aside.
In a large bowl, using a whisk or a hand mixer combine cake mix, with eggs, vegetable oil, sour cream, and honey.
Pour half of the cake batter in the prepared pan.
In a medium bowl, combine brown sugar with cinnamon, and chopped pecans. Sprinkle the mixture over the cake batter
Then pour the remaining cake batter over the cinnamon pecan mixture. The layer of cake batter will be thin, so you will need a spatula to gently spread it out.
Bake in the preheated oven for 35-40 minutes, or until a toothpick comes out of clean from the center of the cake.
As the cake is being baked, make the glaze. In a bowl, combine powdered sugar with milk and vanilla extract. As you remove the warm cake from the oven, pour the glaze directly on it. Allow it to set and the cake to cool, then slice and serve.
