Rotiboy-Style Coffee Bun Toast

Ingredients

• 1 slice white bread, milk bread, or other bread (Use a sturdy slice that can hold the coffee paste.)
• 120 g unsalted butter (Softened.)
• 100 g sugar
• 1 egg (Use at room temperature if possible.)
• 5 g instant coffee powder
• 15 ml hot water (Used to dissolve the coffee powder.)
• 120 g all-purpose flour
• 5 ml vanilla extract
• salt (1 pinch.)

Steps

1. 1

   Preheat the oven to 180°C / 350°F. Line a small baking sheet or toaster-oven tray with parchment paper, if using.

2. 2

   Dissolve the instant coffee powder in the hot water, stirring until smooth and no dry granules remain. Set it aside briefly to cool slightly.

3. 3

   In a bowl, beat the softened butter and sugar together until smooth and creamy.

4. 4

   Add the egg and vanilla extract to the butter mixture, then beat until fully combined. The mixture may look slightly curdled, which is fine.

5. 5

   Add the dissolved coffee and stir until the mixture is evenly coffee-colored and fragrant.

6. 6

   Add the flour and pinch of salt. Mix just until a thick, spreadable paste forms; avoid overmixing once the flour is incorporated.

7. 7

   Place the bread slice on the prepared tray. Spread the coffee paste evenly over the entire top surface, or transfer the paste to a piping bag and pipe it over the bread for a neater finish.

8. 8

   Bake at 180°C / 350°F for 12–15 minutes, until the topping is puffed and beautifully bronze with a lightly crackly surface and the bread is crisp around the edges.

9. 9

   Let the toast cool for a minute or two, then serve warm while the coffee aroma and buttery topping are at their strongest.

Notes

The coffee paste can be made in advance, stored in a jar in the refrigerator, and spread onto bread whenever desired. If refrigerated, let it soften enough to spread or pipe. The source does not specify a bread quantity beyond using a piece of bread; the nutrition estimate assumes one slice.
