Step 1: Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
Step 2: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Step 3: In a large mixing bowl, cream together the softened butter, light brown sugar, and granulated sugar until light and fluffy (about 3-5 minutes).
Step 4: Add the butterscotch pudding mix and beat until combined, then add the eggs one at a time, mixing well after each addition.
Step 5: Gradually add the dry ingredients to the wet mixture, alternating with the milk, beginning and ending with the dry ingredients.
Step 6: Divide the batter evenly between the prepared cake pans and smooth the tops. Bake for 25-30 minutes or until a toothpick comes out clean.
Step 7: Let the cakes cool in the pans for 10 minutes, then turn them out onto wire racks to cool completely before frosting.
