taken from Jessica Seinfeld's book "Deceptively Delicious"

• Ready In: 26 mins
• Yields: 12 muffins

Ingredients

•  nonstick cooking spray
• 1⁄2 cup  firmly packed brown sugar
• 4  tablespoons  trans-fat free margarine, chilled
• 1  cup lemon low fat yogurt
• 1  cup blueberries
• 1⁄2 cup  yellow  squash puree
• 1  large egg
• 2  teaspoons  lemon extract
• 1  teaspoon  grated lemon zest
• 2  cups flour
• 1⁄4 cup flax seed meal
• 1  teaspoon baking powder
• 1  teaspoon baking soda
• 1⁄2 teaspoon salt

Directions

1. Preheat oven to 350. Coat a 12-cup muffin tin with a cooking spray or line with paper baking cups.
2. In a large bowl, beat the sugar and the margarine with a wooden spoon. Stir in the yogurt, blueberries, yellow squash puree, egg, lemon extract, and lemon zest.
3. Add the flour, flaxseed meal, baking powder, baking soda, and salt. Stir just to combine, but do not overmix - the batter is supposed to be lumpy.
4. Divide the batter among the muffin cups. BAke until the tops of the muffins are lightly browned and a toothpick come out clean when inserted in the center, 13 to 16 minutes. Turn the muffins out onto a rack to cool.
5. Store in an airtight container at room temperature for up to 2 days. Or wrap individually and freeze for up to 1 month.
