Set your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving some overhang to lift the bars out easily later.

In a large bowl, mix the melted butter, brown sugar, and granulated sugar until smooth. Stir in the eggs and vanilla until fully combined.

Add the flour, baking powder, and salt. Stir until just mixed—don’t overdo it.

Fold in the shredded coconut, toffee bits, and chocolate chips. Mix gently so everything is spread out evenly.

Pour the batter into the pan and spread it out. Bake for 25–30 minutes, until the top is golden and a toothpick in the center comes out clean or with a few moist crumbs.

Let the bars cool in the pan. Once cooled, lift them out using the parchment, place on a cutting board, and slice into bars or squares.
