Preheat the oven to 350 degrees. Spray a loaf pan with cooking spray.

In a large bowl mix together the flour, baking powder, salt, and chocolate chips. Mix well and set aside.

In another bowl cream together the peanut butter, butter, and sugar.

Add in the egg, milk, and vanilla and mix well to combine.

Add the wet ingredients to the dry ingredients slowly, mixing until combined. Do not over mix.

Pour into the prepared pan. Bake for 1 hour.

Remove from oven and cool for 15 minutes in the pan. Run a butter knife around the edges of the pan and turn out onto the wire rack. Cool completely.

To make the drizzle combine the peanut butter, powdered sugar, and milk in a bowl and whisk until desired consistency is reached. You may need to add more milk or powdered sugar. Drizzle over top of the bread or put in a plastic baggie, snip off the end, and drizzle.

Place the chocolate melts in a microwave safe bowl and heat in 20 second intervals, stirring after each heating, until totally melted. Place in a baggie, snip of the end, and drizzle over top of the bread.
