This recipe makes 16 muffins, so if you don't have two muffin tins, you might want to cut it in half. Although I have no idea how to measure 1/6 cup of something; hopefully you're smarter than me!
The below recipe has been edited to take into account one eagle-eyed reader's astute observation about salt!
In a bowl, mix (or sift, if you're not lazy!) together
1 3/4 cup white whole wheat flour
1/2 cup cocoa powder
3/4 tsp. salt
3/4 tsp. cinnamon
3/4 tsp. baking soda
3/4 tsp. baking powder
In a separate bowl, whisk together
9 oz. okara
1 cup sugar
2/3 cup rum
3/4 cup canola oil
1 1/2 tsp. vanilla
until well emulsified.
Pour liquid ingredients into the dry ingredients and whisk until "just mixed." Then fold in
1/2 cup chocolate chips
Divide batter evenly into 16 wells of lightly oiled muffin pans. Bake at
325 degrees Fahrenheit
for 23-25 minutes. Allow to cool for at least a few minutes before removing from pan.
