1. Either leave the butter to soften at room temperature for a good few hours or lightly melt the butter for 20-30 seconds in a microwave, it makes it easier to spread, it should not be fully liquid, just softened.

2. Spread the butter over both sides of all the bread slices, it doesn't need to be thickly spread but make sure to use all the butter up. You can cut the crusts off if you like, but I prefer to leave them on. Cut the slices across the diagonal.

2. Place the triangles in a deep tin or dish big enough to hold all the slices without too much room around the edges. Scatter the sugar and choc chips between the slices of bread.

3. Beat the eggs, cream, milk and Baileys together in a jug and pour over the bread, lightly press down the bread to help it absorb the custard. Bake on gas 6/200c for 30-40 mins until custard is set and top is browned. Add more chocolate chips to the top if you like!
