My husband has made this boxed [Gluten Free Banana Bread Mix](http://breadsfromanna.com/collections/all/products/banana-bread-mix) a number of times. It's easy, always comes out moist, and stays fresh for 3 or 4 days.

Ingredients:  

1 package Banana Bread Mix from Anna  

2 jumbo eggs  

⅓ cup oil  

3 ripe medium bananas pureed in a food processor or blender 
(approximately 1 cup)  

⅔ cup chopped nuts (optional) (He leaves these out.)

Directions:  

 1. Preheat oven to 350 degrees. Set rack to center.  

 2. Grease 8 ½ x 4 ½ inch. loaf pan.  

 3. In a medium-sized mixing bowl, mix all wet ingredients 
until creamy.  

 4. Add Banana Bread Mix from Anna™ and stir until well 
blended. Fold in chopped nuts.  

 5. Spoon batter into prepared pan and bake for 1 hour, or until 
center tests clean with a toothpick or knife. Let cool in pan 1 hour before slicing.

To add some additional flavor, he'd like to incorporate [powdered peanut butter](http://www.bettylousinc.com/powdered-peanut-butter/powdered-pb.html).
The powder contains only organic peanuts, organic coconut sugar, and salt. (When making peanut butter, the ratio is one tablespoon water for each two tablespoons of powder. That ratio makes a thin consistency of peanut butter, similar to many brands bought off the shelf.) 

Obviously he can't predict the level of peanut flavor, as that would be a matter of trial and error, but he'd like to start by adding 2 tablespoons of powder into the pre-made mix. His concern is that the banana bread will be dry. To avoid that, is there a way to adjust the other ingredients? 

Here are some pictures of the peanut powder:

It's a light, loose consistency which looks like this:
