Banana Peanut Butter Chocolate Chip Streusel Muffins

I made these gigantic muffins as thank you gifts for some ladies at our church.  I don't make muffins often, and I make banana muffins even less often, but I thought that these would be the perfect casual treat to say thanks.  These muffins are stuffed with banana flavor and topped with a crispy streusel studded with peanut butter chips and chocolate chips.  Delicious! Original recipe found here.

Banana Peanut Butter Chocolate Chip Streusel Muffins

Banana Muffins:
1/2 cup butter, room temperature
2/3 cup packed brown sugar
4 ripe bananas, mashed (about 2 cups)
2 eggs
1 teaspoon vanilla extract
2 cups all purpose  flour
1 teaspoon baking soda
1 teaspoon cinnamon
1/2 teaspoon salt

Peanut Butter Chocolate Chip Streusel:
1 cup all purpose flour
1/2 cup packed brown sugar
1/4 cup butter, melted and cooled slightly
1/4 cup peanut butter chips
1/4 cup mini chocolate chips

Preheat the oven to 350F.  Line 6 jumbo muffin cups with paper liners (if you'd like smaller muffins, line 12 to 18 regular size muffin cups with paper liners).

In a large bowl, cream together the butter and brown sugar until light and fluffy.  Beat in the bananas, eggs, and vanilla extract.  Add the flour, baking soda, cinnamon, and salt, and beat on low just until combined and no streaks of flour remain.  Scoop the batter into the prepared muffin cups, filling each about 2/3 to 3/4 full.  Set aside.

For the streusel, stir together the flour and brown sugar.  Add the melted butter and toss mixture together until evenly moistened and crumbly.  Stir in the peanut butter chips and mini chocolate chips.  Spoon the streusel over the unbaked muffin batter (you may have a little bit left over).  Bake the muffins for about 25 to 30 minutes (for regular size muffins about 15 to 20 minutes), or until a toothpick inserted in the center comes out clean. Remove muffins from the oven and place on a cooling rack.  Makes 6 jumbo muffins (12 to 18 regular size muffins).

Enjoy!  -Cardamommy
