1. Melt butter in large saucepan over medium heat. Add onion; sauté 3 minutes. Add garlic and apple; cook, stirring constantly, 1 minute. Add squash and next 4 ingredients; stir 30 seconds or until well-combined. Add broth, and bring to a simmer. Reduce heat to medium-low; simmer 20 minutes or until squash and vegetables are tender.
2. Place half of squash mixture in blender with 1/4 cup evaporated milk. Remove center of blender lid (to let steam escape); secure lid. Place clean towel over opening to avoid splatters; blend until smooth. Pour into bowl. Repeat with remaining squash and evaporated milk.
3. Spoon 1/2 cup soup into small bowl or mini pumpkin. Swirl in 3/4 teaspoon crème fraîche, if desired. Serve immediately.
