Preheat oven to 350 (325 for convection oven). Beat butter and cream cheese with mixer at medium speed until creamy. Gradually add sugars, beating until light and fluffy. Add eggs, 1 at a time, beating just until blended after each addition. Stir together flour and next 4 ingredients; gradually add to butter mixture, beating at low speed. Stir in pumpkin and next 3 ingredients. Spoon batter into 2 lightly greased 12-cup muffin pans (or four or five small loaf pans sprayed with cooking spray), filling two-thirds full. Sprinkle with Pumpkin Pie Streusel. Bake at 350 (or 325) for 25 minutes (or longer for loaves) until a wood pick inserted in center comes out clean. Cool in pans on wire racks 5 minutes. Remove from pans to wire racks, and cool 20 minutes. Pumpkin pie streusel: stir together the chopped pecans, light brown sugar, flour, melted butter and pumpkin pie spice. (I used just one recipe of streusel for the seven loaves I made.) This recipe could be made gluten-free by substituting a mixture of sorghum flour and brown rice flour for the all-purpose flour.
