Preheat oven to 350 degrees. Butter and lightly flour a standard bundt cake pan. Set aside.

Step 2

In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.

Step 3

In a large bowl, cream together the softened butter and sugars. Add in the eggs, bananas, bourbon, and vanilla and mix until well combined. Beat in the flour mixture in three additions, alternating with the sour cream. Fold in the chopped pecans. Spread batter into prepared bundt pan.

Step 5

To make the Bourbon Butter Glaze, melt butter in a small saucepan over medium heat. Whisk in the powdered sugar, bourbon, and vanilla until smooth and well combined.
