1. Preheat the oven to 350 degrees Fahrenheit and oil or line 36 wells in mini muffin tins.
2. Combine the sugar, cocoa powder, flour, salt, baking soda, and baking powder in a large mixing bowl. Stir with a whisk until evenly combined.
3. In a separate small bowl, mash the banana.
4. Add the mashed banana, oil, non-dairy milk, and vanilla extract to the bowl with the dry ingredients. Mix until a smooth batter forms.
5. Use a cookie scoop or spoon to portion the batter into the mini muffin tins. Fill each well only 2/3 of the way to prevent overflow.
6. Bake at 350 degrees Fahrenheit for 15 minutes or until an inserted toothpick comes out clean.
7. Let the brownies cool to room temperature before decorating.

To Decorate the Brownie Bites

1. Spread a thin layer of black or chocolate vegan frosting on each brownie bite.
2. Using a fine-tipped piping bag or prepared tube of white decorator icing (vegan), make a dot in the center of each brownie and 2 concentric circles. The brownies should look like bullseyes.
   
3. Using a toothpick or cocktail stick starting from the center dot, gently drag the tip from the center outward 5-8 times to create the spider web design.
   
4. That's it! Serve and enjoy!
