Ingredients:
- 170g unsalted European-style butter
- 150g high-quality white chocolate, chopped
- 20g culinary grade matcha powder
- 150g granulated sugar
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 125g all-purpose flour
- 0.5 tsp fine sea salt
- 0.25 tsp baking powder
Instructions:
- Brown the butter: Melt the 170g of unsalted butter in a light-colored saucepan over medium heat, swirling until the milk solids turn amber and smell nutty. Remove from heat immediately.
- Create the matcha base: Stir the chopped white chocolate into the hot browned butter until melted. Sift in the 20g of matcha powder and whisk until the mixture is smooth and vibrant green.
- Aerated foam: In a separate large bowl, use an electric mixer to beat the 2 eggs and 150g sugar with vanilla for 5 minutes until the mixture is pale, thick, and has tripled in volume.
- Emulsify: Gently fold the matcha-butter-chocolate mixture into the egg foam using a spatula, being careful not to deflate the air bubbles.
- Dry ingredients: Sift the 125g flour, salt, and baking powder over the wet base. Fold gently until no streaks of flour remain.
- Bake: Pour the batter into a lined 8x8 inch pan. Bake at 350°F (180°C) for 25 minutes. The center should be set but still slightly soft to ensure a fudgy texture.
