Start by scooping your vanilla ice cream into a microwave-safe bowl and heating it in short bursts until it's fully melted. I usually stir it every fifteen seconds so it melts evenly without getting too hot. Pour the melted ice cream into a large baking dish so it's ready for the bread.
Place your bread slices into the melted ice cream and let them sit for about three minutes. Flip each slice and let it soak for another minute or two until saturated but not falling apart. I keep a close eye on this step because soggy bread is much harder to fry properly.
While the bread soaks, heat two tablespoons of butter in a large skillet over medium heat. I like to let the butter get slightly foamy before adding anything, since that means it's hot enough to create a nice golden crust.
Using tongs, lift two slices of bread from the dish, letting any extra liquid drip off. Place them into the hot skillet and cook for about four minutes per side, until golden brown and springy in the center. Repeat with the remaining butter and bread slices.
Once all the slices are cooked, plate them up right away while they're still warm. I always add a pat of butter on top so it melts slightly into the toast before drizzling on syrup and any fruit I have on hand.
