Pumpkin Pecan Crunch Muffins

"My daughter loves pumpkin desserts. During this time of year, she can never get enough of anything pumpkin (especially pumpkin pie). These simple Pumpkin Pecan Crunch Muffins are the perfect snack for anytime of the day. They speak fall! A delicious pumpkin batter, laced with the traditional pumpkin flavors of cinnamon, nutmeg, and cloves, is mixed with a generous helping of crunchy pecans. Top these babies off with a nice crunchy streusel topping and you have a perfect fall muffin."
