Preheat oven to 350°F (177°C). Line an 8 x 4 inch loaf pan with parchment paper.
Add white chocolate chips to a large microwave-safe mixing bowl. Heat chocolate in 15-30 second intervals, stirring in between with a spatula until chocolate is completely melted and smooth. You can also melt the chocolate on the stove using the double boiler method.
Add in applesauce. Using a whisk, mix until the mixture becomes uniform and no white chocolate streaks remain.
Sift in the flour. This can be done by simply adding the flour through a small mesh strainer. Whisk in the added flour until it is fully incorporated into the batter and no flour lumps remain.
Pour batter into your prepared baking loaf pan. Bake for about 30-35 minutes or until the surface is a medium golden brown. The longer you bake, the chewier the edges will be so I baked mine the full 35 minutes. A toothpick inserted should come out clean. Let brownies cool fully before cutting and serving.
Notes
You can also double this recipe and bake in an 8 x 8 inch pan. I prefer to bake this in a loaf pan because every piece has an edge which is where the brownie is chewiest. If you bake in bigger pan, the middle pieces won't be as chewy.
I recommend using unsweetened applesauce because the brownies are already very sweet from the white chocolate.
Make sure to measure out the applesauce carefully. Adding too much will make the brownies more fudgy and soft and they will not get chewy.
The flour should be sifted in, otherwise it will be very difficult to mix out the flour lumps.
