Preheat the oven to 325°F (163°C). Grease and flour a bundt pan thoroughly.
In a large bowl, cream together the butter (including infused butter) and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Mix in vanilla extract, almond extract, coconut extract, lemon extract, lemon juice, and lemon zest until fully combined.
In a separate bowl, whisk together flour and instant lemon pudding mix.
Alternate adding dry ingredients and evaporated milk to the butter mixture, beginning and ending with dry ingredients. Mix until just combined. Do not overmix.
Fold in sour cream until batter is smooth and thick.
Pour batter into prepared bundt pan and smooth the top.
Bake for 75–90 minutes, or until a toothpick inserted in the center comes out clean.
Allow cake to cool in the pan for 15–20 minutes, then invert onto a cooling rack and cool completely.
For the glaze, melt butter in a small saucepan and cook until browned and nutty in aroma. Remove from heat and whisk in powdered sugar, vanilla paste, lemon extract, and milk until smooth.
Drizzle glaze over cooled cake and allow it to set before slicing.
