Butter Tart Muffins recipe.

Ingredients
1 1/2 cups raisins
3/4 cup white sugar
1/2 cup butter, cut into pieces
1/2 cup milk
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
salt to taste
1/2 cup chopped walnuts
1/4 cup corn syrup

Directions
Place raisins, sugar, butter, slightly beaten eggs, milk, and vanilla in a large heavy-bottomed saucepan. Cook over medium heat, stirring frequently, until mixture is hot, slightly thickened, and just beginning to bubble. Cool slightly, uncovered, in the refrigerator.
Stir flour with baking powder, baking soda, and salt in a large mixing bowl. Make a well in centre, and pour in warm raisin mixture; stir just until combined. Stir in nuts until evenly mixed. Spoon batter into greased muffin cups.
Bake in center of oven at 350 degrees F (190 degrees C) until golden, about 15 to 17 minutes. Remove from oven, and immediately pour about 1 teaspoon syrup over each muffin. Cool muffins in pan for 10 minutes, then remove to a rack. Serve warm.
