Viral Custard Toast Recipe
Make the Viral Custard Toast Recipe for a quick, impressive breakfast with crisp brioche, creamy custard, and fresh berries.
Ingredients
- 4 slices thick-cut brioche or soft white sandwich bread (about 1/2 inch / 1.5 cm thick each, total about 200 g), slightly stale or day-old if possible
- 1 large egg (about 50 g), at room temperature
- 1/3 cup (80 g) full-fat Greek yogurt, at room temperature
- 2 tablespoons (25 g) granulated sugar
- 1/2 teaspoon pure vanilla extract
- 1 small pinch fine sea salt (about 1/16 teaspoon)
- 1/2 cup (75 g) fresh mixed berries, rinsed and patted dry (such as blueberries, sliced strawberries, or raspberries)
- 1 tablespoon (15 g) mini chocolate chips or finely chopped dark chocolate (optional)
- 1 teaspoon (4 g) coarse sugar or turbinado sugar for sprinkling on top (optional, for extra crunch)
- 1 tablespoon (8 g) powdered (confectioners’) sugar, for dusting (optional)
- 2 tablespoons (30 ml) pure maple syrup or honey, for serving (optional)
Instructions
Step 1: Preheat the oven and line the tray
Preheat your oven to 375°F (190°C) and position a rack in the middle. Line a rectangular baking sheet with a piece of parchment paper or a silicone baking mat so nothing sticks; this is the only heat-transfer object that will appear later on the marble surface. Keep the tray and parchment visible on the marble—clean, simple, ready.
Step 2: Shape the brioche wells on the tray
Lay the four slices of slightly stale brioche flat on the lined baking sheet with a little space between each. Using the back of a spoon or your fingers, gently press the center of each slice to form a shallow well, leaving a neat 1/2-inch border to hold the custard. The slices should read as soft, pillowy squares with a clearly depressed center and intact golden rims on the uncooked dough.
Step 3: Combine the custard ingredients in one bowl
In a single medium matte grey ceramic bowl at room temperature add the egg, full-fat Greek yogurt, granulated sugar, vanilla extract, and a small pinch of fine sea salt. Keep all wet ingredients contained in clear glass or ceramic vessels until added—no liquids ever on the marble itself. This step is about organized, calm assembly of components.
Step 4: Whisk to a smooth, thick custard
Whisk vigorously by hand for 30–45 seconds until the mixture is completely smooth, glossy and thick—no streaks of white egg or lumps of yogurt. The texture should be close to a thick pancake batter: viscous, shiny, and able to hold soft peaks for a second before settling back. Rest the whisk inside the bowl or across the rim so it reads as the active tool.
Step 5: Spoon custard into each brioche well
Divide the custard evenly, roughly 2 heaping tablespoons per slice, and spoon it into the pre-formed wells, spreading gently toward the edges while keeping the raised border intact. Each slice should show a neat, glossy, pale custard dome sitting within the bread collar—no spillover, clear borders.
Step 6: Arrange berries and optional add-ins
Top each custard-filled well with the fresh mixed berries, pressing them lightly so they adhere; scatter mini chocolate chips or chopped dark chocolate if desired, and finish with a tiny pinch of coarse turbinado sugar for crunch. The toppings should sit slightly embedded in the custard, color-popping against the pale custard surface.
Step 7: Bake until edges are golden and custard set
Place the assembled baking sheet into the preheated oven and bake 10–13 minutes until the bread edges are golden-brown and crisp and the custard is just set—slightly puffed and glossy with a faint central wobble when the tray is nudged. The visual cue is a gently domed custard with a mirror-like sheen and crisply browned bread rims.
Step 8: (Air-fryer alternative) replicate the baked result
If using an air fryer, arrange 2–4 slices in a single layer in a parchment-lined air-fryer basket and cook at 350°F (180°C) for about 6–8 minutes until you achieve the same golden rims and just-set custard. The resulting texture should match the oven version: glossy custard, puffed centers, and crisp edges.
Step 9: Cool briefly on the tray
Remove the tray from the heat and let the toast cool for 2–3 minutes right on the parchment. This short rest lets the custard finish setting while preserving a soft, creamy center—avoid overbaking so it remains tender, not rubbery.
Step 10: Dust and drizzle just before serving
Just before serving, dust the tops lightly with confectioners’ sugar and, if you like, drizzle a little maple syrup or honey from a small glass jar. The sugars should sit delicately on the glossy custard and berries, creating tiny matte contrasts and a hint of sticky sheen.
Step 11: Serve warm and store thoughtfully
Serve the custard toast warm for the best contrast between crisp edges and a creamy center; plate on a rectangular serving platter to echo the baking sheet geometry. Enjoy within 15–20 minutes for crispiest edges; cool completely for storage and refrigerate up to 1 day, reheating in a 350°F (180°C) oven or air fryer until slightly crisp again.
Notes
- Use slightly stale brioche for better structure and crisper edges.
- For vegan versions substitute plant-based yogurt and a flax or chia egg replacer.
- Do not overfill wells; roughly 2 heaping tablespoons custard per slice is ideal.
- Reheat in a 350°F (180°C) oven or air fryer to restore crispness.
- Store leftovers in an airtight container in the fridge for up to 24 hours.
