Types and Calories of Peanut Butter Sandwiches

There are as many peanut butter sandwich types as you can imagine. From basic ones that contain only bread and peanut butter to more exotic ones that can contain whatever your mind can think of.

That is why the number of calories in a peanut butter sandwich varies, depending on the content of the sandwich.

Usually, peanut butter sandwiches are made from bread, jelly, or jam, and peanut butter. They can often be made with added chocolate, maple syrup, honey, dried fruits, or bananas.

And of course, there can be other additions depending on individual taste, but they all add to the total amount of calories of the sandwich.

Typically chosen bread for peanut butter sandwiches is white (approx. 74 calories per slice), wheat (approx. 77 calories per slice), or whole wheat bread (approx. 81 calories per slice).

Honey, maple syrup, or jelly contains approximately 60 calories per tablespoon, and a medium-sized banana has an average of 100 calories.
