One of my favorite snacks is peanut butter with apples and so the idea to combine the two in a muffin came to me. I looked around online and did not find any apple peanut butter muffin recipes that I was happy with so I looked up a simple apple muffin receipe that I used before and knew was quite good. I added the peanut butter by melting it down and using it in place of the vegetable oil the recipe called for. And to give a little extra peanut butter flavor to the muffins for the cinnamon sugar crumble topping I replaced the butter with melted peanut butter.
The addition of the peanut butter makrs the batter a little thick and the muffins come a little dense and quite rich but the combination of flavors of cinnamon, peanut butter and apple is really good. If you cut the apples into fairly large chunks when you get a bite of them in the muffin you cab really taste the cinnamon flavor soaked into the apple almost like with an apple pie.
