For Streusel Topping, combine pecans, brown sugar, flour and butter with a fork until crumbly; set aside. For Muffins, beat eggs in large bowl with electric mixer; gradually add sugar. With mixer running pour in vegetable oil and almond extract, blending until smooth. In separate bowl whisk together flour, baking powder, salt, and baking soda. Add flour mixture to egg mixture, alternating with the sour cream; blend until smooth. Set aside. Pat each cream cheese piece into a disk the size of a quarter. Spoon one generous Tbsp. batter into bottom of muffin tins. Divide half of raspberries equally among muffin cups. Top each muffin cup with a cream cheese disk. Divide remaining batter among muffin cups, spooning over the cream cheese. Top with remaining equally divided raspberries. Sprinkle each muffin with streusel topping. Bake at 375° F for 20 to 25 minutes. Let stand for 5 minutes in tins on cooling rack. Remove from tins to rack to cool completely. Serves 16.
