Melt butter in a saucepan over medium heat.
Stir in brown sugar until fully dissolved.
Whisk in heavy cream and simmer for 3–4 minutes until smooth and slightly thickened.
Stir in vanilla and a pinch of salt. Allow to cool completely.
Step 2 – Make the Cake
Preheat oven to 350°F (175°C). Grease and flour three 8-inch (20cm) round cake pans.
In a large bowl, cream butter and brown sugar until light and fluffy.
Beat in eggs one at a time, then add vanilla.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
Add the dry ingredients to the wet mixture alternately with milk, mixing until smooth.
Stir in ½ cup of cooled butterscotch sauce for extra flavor.
Divide the batter evenly among the prepared pans and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool completely before frosting.
Step 3 – Make the Frosting
Beat softened butter until creamy.
Gradually add powdered sugar, mixing until smooth.
Mix in cooled butterscotch sauce.
Add heavy cream as needed to reach a spreadable consistency.
Step 4 – Assemble the Cake
Place one cake layer on a serving plate. Spread frosting evenly on top.
Repeat with the second and third layers.
Frost the top and sides of the cake.
Drizzle extra butterscotch sauce over the top for a glossy finish.
