1. Preheat Oven: Preheat your oven to 425°F (220°C).

3. Spread Mixture: Generously spread the garlic butter mixture onto one side of each slice of Texas toast.
4. Add Cheese: Sprinkle an equal amount of cheddar and mozzarella cheese on top of the buttered side of each slice.
5. Arrange on Baking Sheet: Place the slices on a baking sheet, ensuring they are flat and not overlapping.
6. Bake: Bake in the preheated oven for 10-15 minutes or until the edges are golden and the cheese is bubbly.
