Jumbo Lemon Blueberry Costco Muffins Recipe
Description
Jumbo Lemon Blueberry Costco Muffins Recipe makes large muffins bursting with fresh blueberries and lemon zest. The recipe uses a blend of all-purpose flour, sugar, baking powder, baking soda, and salt for the base dry ingredients. Wet ingredients include eggs, buttermilk, vegetable oil, plain yogurt, melted butter, freshly grated lemon zest, and vanilla extract, which together create a moist but sturdy batter. The blueberries fold gently into the batter to distribute evenly without breaking until baking.
The muffins bake at 375°F (190°C) in a buttered jumbo muffin tin for about 35 to 40 minutes, developing a golden crust while keeping the interior soft and tender. They cool in the pan briefly before serving, and are best the day they are made but can be stored airtight at room temperature for a couple of days or frozen for longer keeping.
These muffins are excellent for a filling breakfast or an easy snack, showcasing the brightness of lemon paired with the sweet juiciness of blueberries in a sizable, satisfying portion.
