Preheat the Oven: Position a rack in the lower third of your oven and heat it to 350°F. Line an 8×8-inch baking dish with parchment paper so it extends up the sides like handles. Lightly coat with nonstick spray.
Start the Brownie Base: In a medium saucepan over low heat, gently melt the butter and coconut sugar together. Stir continuously until the mixture looks smooth and begins to resemble caramel. Remove it briefly from heat and mix in the honey. Set the pan back on the stove and continue warming until glossy and cohesive, but be sure not to let it boil—this should take about 30 seconds to a minute.
Add Cocoa and Wet Ingredients: Take the pan off the heat. Use a wooden spoon or spatula to blend in cocoa powder, salt, baking powder, and baking soda. Then mix in vanilla extract and applesauce. Add one egg, stir until fully incorporated, then repeat with the second egg until the batter becomes thick and shiny.
Mix in Flour and Chips: Sprinkle the flour over the batter and stir just until no dry streaks remain. Keep folding for another 40 stirs to develop a luscious, glossy texture. Gently fold in the chocolate chips. Spread the mixture evenly into your prepared pan.
Bake: Place in the oven and bake for 22 to 25 minutes, or until a toothpick inserted in the center comes out with only a few moist crumbs. Allow to cool in the pan on a wire rack completely.
Prepare the Topping: Arrange the sliced strawberries over the cooled brownies. In a microwave-safe bowl, combine dark chocolate and coconut oil. Microwave for 30 seconds, then in 15-second bursts, stirring each time until smooth. Alternatively, melt in a small saucepan on low heat.
Finish and Chill: Drizzle the melted chocolate over the strawberries. Let the brownies sit at room temperature until the chocolate sets (about 30 minutes), or place them in the fridge for faster setting. Once set, lift the brownies out using the parchment handles, slice, and serve.
