Instructions
Preheat the oven to 425 degrees Fahrenheit. In a bowl whisk together the flour, baking powder, baking soda, and salt. Set aside.
In a separate bowl, cream together butter, sugar, and light brown sugar for 2 minutes. Add in eggs, vanilla, rum extract, and butter extract and whip for 2 minutes until super smooth and light and fluffy.
Add the sour cream and buttermilk and mix on low until smooth.
Then add in the dry ingredients. Mix until just barely incorporated, scrape down the sides and make sure there are no pockets of flour then stir in the butterscotch chips.
Line a muffin pan with paper liners, and divide the batter between 12 muffins. If you want your muffins to rise extra, only fill every other slot (this may mean you do two batches). Top with a few extra butterscotch chips if desired.
Bake at 425 for 5 minutes, then reduce the temperature to 375 degrees and bake for an additional 11-14 minutes. Watch them closely so they don’t get too dark.
While baking, make the butter rum syrup. Place the water, sugar, and butter in a small pan and bring to a boil. Let boil for 2 minutes, then remove from heat and stir in the vanilla and rum extract.
Let the muffins cool for 5 minutes before removing them from the pan. Brush the tops of the muffins with the butter rum syrup generously while the muffins are still hot.
