A blueberry yogurt cake is a delightful and nutritious choice for a kids' birthday celebration. This cake is made with whole wheat flour, Greek yogurt, and fresh blueberries. The yogurt adds moisture and a tangy flavor, while the blueberries provide antioxidants and natural sweetness. You can serve it plain or top it with a light glaze made from powdered sugar and lemon juice. This cake is a great way to incorporate fruits and probiotics into your child's diet.
