6–8 slices (1-inch-thick or 2.5 cm) bread, preferably day old (see notes)
Coconut oil (optional)
Add all the ingredients to a blender (except the bread and the coconut oil) and blend until smooth. Pour the mixture into a baking dish or a shallow bowl and let stand for 5 minutes at room temperature.
Place each slice of bread into the mixture, allowing the bread to soak in some of it on both sides.
Heat some coconut oil in a griddle or a hot skillet, and place the bread slices onto the griddle/hot skillet until browned on one side, then flip and brown the other side (about 5 minutes for each side).
