Recipe Information
Ingredients
- 4 cups All-purpose flour
- 2 cups Granulated sugar
- 1 tablespoon Baking powder
- 1 teaspoon Baking soda
- 1 teaspoon Salt
- 4 large Eggs
- 1 cup Vegetable oil
- 1.5 cups Whole milk
- 2 teaspoons Vanilla extract
- 2 cups Add-ins (chocolate chips, blueberries, or chopped nuts)
Instructions
Preheat your oven to 375°F (190°C) and grease or line a jumbo muffin tin with paper liners.
In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
In a separate bowl, beat the eggs, then add in the vegetable oil, milk, and vanilla extract. Mix until fully integrated.
Pour the wet ingredients into the dry ingredients, stirring gently until just combined. Be careful not to overmix; the batter should be slightly lumpy.
Fold in your chosen add-ins (such as chocolate chips, blueberries, or nuts) with a spatula until evenly distributed in the batter.
Scoop the batter into the prepared muffin tin, filling each cup almost to the top to achieve that signature jumbo muffin dome.
Bake in the preheated oven for 25-28 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before serving.
