These lemon curd muffins are a delightful treat for breakfast or a snack. The muffin batter is made with flour, sugar, baking powder, milk, eggs, and a generous amount of lemon zest for a burst of citrus flavor. Once the muffins are baked, they are filled with a dollop of tangy lemon curd. The combination of the moist and fluffy muffin with the creamy lemon curd creates a perfect balance of flavors. These muffins are perfect for on-the-go breakfasts or as a sweet treat with a cup of tea.
