Healthy Brownie Bites

Preheat oven to 350 degrees F. Line a mini-muffin pan with paper liners.

Melt butter in a large saucepan over medium-low heat. Remove from heat. Add unsweetened chocolate and stir until melted. Add sugar and salt; stir until well combined. Stir in zucchini and vanilla. Add eggs, one at a time, mixing vigorously after each addition. Fold in flour until almost incorporated. Fold in chocolate chips. Using about 2 tablespoons per cup, spoon the batter into the prepared cups. They will be full.

Bake until the brownie bites are firm to the touch and a toothpick inserted in the center comes out clean, 20 to 25 minutes. Remove the brownie bites to a wire rack when cool enough to handle.
