2large (65 g)egg whites, brought to room temperature
3tbsp (24 g)all purpose flour
Instructions
Preheat oven to 350°F (177°C). Line an 8 x 4 inch baking loaf pan with parchment paper.
Add white chocolate chips and lemon juice to a large microwave-safe mixing bowl. Heat chocolate in 15-30 second intervals, stirring in between with a spatula until the mixture is completely melted, smooth and uniform in color. You can also melt the chocolate and lemon juice on the stove using the double boiler method.
Add in the egg whites. Use a hand wire whisk to vigorously whisk the egg whites into the batter, making sure to break up the egg whites and incorporate them completely. Whisk until no streaks of egg whites remain.
Sift in the flour using a mesh strainer, 1 tbsp at a time, whisking until the batter is smooth after each addition. Finally, stir in the lemon zest until it is evenly mixed in.
Pour batter into your prepared baking pan. Bake for about 32-38 minutes or until the edges are dark brown, surface is lightly browned and a toothpick comes out mostly clean. Mine were done at 35 minutes. Let brownies cool completely before cutting and serving. You can also frost the brownies after they are cooled.
Notes
Use a good brand of white chocolate chips and use a fresh bag. Some of the cheaper brands do not melt well. If your white chocolate is old it also won't melt well. I used Nestle white chocolate chips.
These brownies are very rich so I don't recommend slicing them too big. I also think they bake best in a loaf pan so that every piece has edges which make the brownies chewy.
2 large egg whites should equal about 65 grams.
Optional Frosting: The brownies are already quite sweet without the frosting so it's not really needed, but it will make the brownies look nicer. If you want to make the frosting I used, here it is:
1/2 cup powdered sugar
heaping 1/2 tbsp lemon juice
lemon zest for garnish
Whisk powdered sugar and lemon juice together until smooth. If you want your frosting to be thicker you can add a little more sugar. If you want it to be thinner, you can add a little more lemon juice. Spread frosting over brownies. Sprinkle zest over frosting. Let frosting set before cutting brownies.
