## Prep notes
- Line a microwave-safe 8x8 inch glass dish or suitable container with parchment paper for easy removal.
- Melt butter and chocolate in short 20 to 30-second intervals to prevent scorching.

## Ingredients
- 115 g unsalted butter (cut into pieces)
- 60 g semi-sweet chocolate (chopped)
- 150 g granulated sugar
- 10 g espresso powder
- 120 g large eggs plus 1 yolk (room temperature)
- 5 g vanilla extract
- 60 g all-purpose flour
- 1 g kosher salt

## Method
1. **Melt Base**
  - **Melt butter:** Place butter in a microwave-safe bowl and heat in 30-second bursts until fully melted.
  - **Melt chocolate:** Add chopped chocolate to the warm butter, letting it sit for 1 minute, then stir until smooth.

2. **Sweeten & Flavor**
  - **Whisk sugar:** Vigorously whisk in the granulated sugar and espresso powder until slightly glossy.

3. **Enrich Batter**
  - **Whisk eggs:** Ensure the mixture is slightly cooled, then whisk in the eggs, extra yolk, and vanilla extract until smooth.

4. **Fold Dry**
  - **Fold flour:** Gently fold in the all-purpose flour and salt using a spatula just until no dry streaks remain.

5. **Microwave Cook**
  - **Microwave batter:** Pour batter into the prepared microwave-safe dish and microwave on medium power. · 3 to 4 minutes · Look for: Edges are set but the center remains slightly soft and glossy

6. **Rest & Cool**
  - **Rest brownies:** Let the brownies rest at room temperature so carryover heat finishes setting the center. · 10 minutes · Look for: Firm to the touch with moist crumbs on a toothpick

## Why it works
Melting chocolate and butter together creates a rich emulsion, while espresso powder intensifies the cocoa notes without adding excess liquid. Short microwave intervals prevent overcooking, and resting allows carryover heat to achieve a fudgy crumb.

## Failure modes
- Overcooking in the microwave leads to dry, cakey brownies; stop cooking when the center is still slightly soft.
- Adding eggs to a boiling-hot fat mixture can curdle them; let the melted chocolate-butter base cool slightly first.
