Directions :
- Preheat and prepare pans: Heat oven to 350°F (175°C). Grease two 9-inch round pans. Line with paper and grease again.
- Make the cake batter: In a bowl, mix flour, baking powder, baking soda, and salt. In another bowl, beat butter and 1 1/2 cups sugar until light. Add eggs one at a time. Mix in vanilla. Add dry mix in three steps, with buttermilk in between. Mix until smooth.
- Bake the cakes: Divide batter into pans. Smooth tops. Bake 25–30 minutes or until a toothpick comes out clean. Cool 10 minutes in pans, then move to racks to cool fully.
- Make the caramel sauce: In a heavy pan, melt 1 cup sugar on medium heat. Stir until it turns amber. Add 6 tbsp butter and stir. Slowly add 1/2 cup heavy cream and a pinch of salt. Stir until smooth. Let cool and add crushed toffee and pecans if you like.
- Prepare the frosting: Beat 1 1/2 cups butter until soft. Add powdered sugar slowly. Mix in 1/4 cup cooled caramel, vanilla, and 2 tbsp cream. Beat until light. Add more cream if it is too stiff.
- Assemble the cake: Place one cake layer on a board. Spread a thin layer of frosting. Spoon some caramel sauce on top and spread gently. Sprinkle crushed toffee. Add the second cake layer. Frost the top and sides with the remaining frosting.
- Add the final touch: Drip a little caramel on top. Scatter more toffee and nuts on the top. Chill the cake for 30 minutes to set the frosting and caramel.
