Step 1

Place a rack in the center of your oven and preheat the oven to 350 degrees F. Grease and flour a large (10 or 12-cup) bundt pan and set aside.

Step 2

In a large mixing bowl, stir together the cake and pudding mixes. Add the milk and water and stir to combine. Beat in the eggs one at a time, combing well after each, then add the butter and vanilla extracts. Beat for 6 minutes at high speed.

Step 3

In a small bowl, stir together the streusel ingredients: granulated sugar, cinnamon, and pecans. Pour half of the batter into the prepared pan, sprinkle with all of the cinnamon-sugar mixture, then pour the remaining batter over the top. Bake the cake in the center of the oven until golden and a skewer inserted in the center comes out clean, 50 to 60 minutes. Set the pan on a wire rack and let cool for 8 minutes, then turn the cake out of the pan and let cool completely.

Step 4

For the glaze: beat together the powdered sugar, milk, butter extract, and vanilla extract until smooth. Drizzle over the cooled cake. Slice and serve.
