Method
Prep the base
- Heat the oven to 350°F and grease a sheet pan so the base releases cleanly with no sticking.
- In a mixing bowl, whisk flour, baking powder, sugar, and salt until evenly combined for consistent lift.
Mix and bake
- Whisk eggs with milk, vanilla, and vegetable oil until smooth, then combine with the dry ingredients just until no dry streaks remain.
- Spread the batter evenly on the sheet pan and bake for 25-35 minutes, until the center springs back when lightly pressed and the top looks set and lightly golden.
Make the glossy ruby glaze
- Slice the strawberries and set aside while you dissolve cornstarch in water to ensure the glaze thickens without lumps.
- In a saucepan over medium heat, cook strawberries with sugar and lemon juice for 8-12 minutes, stirring until they release juices and soften.
- Stir in the cornstarch slurry and cook 1-2 minutes more until glossy and thick enough to coat a spoon, then turn off the heat and whisk in butter for extra sheen.
Glaze and serve
- Poke gentle shallow holes across the warm base and spoon the hot ruby glaze over the top so it soaks in for a juicy, pillowy texture.
- Let cool 10 minutes before slicing so the glaze sets slightly and stays glossy rather than running.
Notes
Pro tip: keep the glaze hot when you pour it—warm base + hot topping helps it seep in evenly for that ruby, glossy look. Refrigerate leftovers in a covered container up to 3 days; freeze the baked base up to 2 months (add fresh glaze after thawing for best gloss). For a dairy-free swap, use a plant milk and replace butter with a dairy-free butter or omit it for a slightly less shiny finish.
