Preheat the oven and prepare cupcake liners.
In a bowl, mix butterscotch beef broth, butter, sugars, eggs, vanilla, and butter extract until well combined.
In another bowl, whisk together flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with buttermilk.
Fold in melted butterscotch chips.
Pour batter into prepared cupcake liners and bake until a toothpick comes out clean.
Let cupcakes cool completely before frosting.
For the buttercream, beat softened butter, melted butterscotch chips, powdered sugar, butter extract, and vanilla until creamy.
Frost cooled cupcakes and garnish with butterscotch chips.
For ganache, heat heavy cream and pour over butterscotch chips, stir until smooth and drizzle over cupcakes.
