Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Add in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, whisk together the flour, baking powder, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, alternating with the butterscotch chips until well combined.

Pour the batter into the prepared cake pan. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Once baked, remove the cake from the oven. Immediately sprinkle the toffee bits on top for an added crunch.

Let the cake cool in the pan for about 15 minutes before transferring it to a wire rack. Once cooled, slice, serve, and enjoy the praises!
