Creating Coconut Toffee Bars is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. Mix Wet Ingredients: In a large mixing bowl, combine the melted butter, granulated sugar, and brown sugar. Mix until smooth.
3. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract until well combined.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. Fold in Coconut and Toffee: Gently fold in the shredded coconut and toffee bits (and nuts if using) until evenly distributed.
7. Pour into Pan: Spread the mixture evenly in the prepared baking pan.
8. Bake: Place in the preheated oven and bake for 30-35 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and allow to cool in the pan for about 20 minutes before cutting into squares.
10. Serve: Enjoy your delicious Coconut Toffee Bars warm or at room temperature.
