Tangy Rhubarb Muffins (Print Version)

# Ingredients:

→ For the muffin batter

01 - 3/4 cup granulated sugar
02 - 3/4 cup packed brown sugar
03 - 1/2 cup vegetable oil
04 - 1 cup buttermilk (or make your own with milk and vinegar)
05 - 1 large egg
06 - 1 teaspoon pure vanilla extract
07 - 2 3/4 cups all-purpose flour
08 - 1 teaspoon baking soda
09 - 3 cups fresh rhubarb, diced into small pieces

→ For the cinnamon sugar topping

10 - 1/2 cup granulated sugar
11 - 1/2 teaspoon ground cinnamon
12 - 1 tablespoon butter, softened

# Instructions:

01 - Heat your oven to 350°F and line 24 muffin cups with paper liners or give them a light coating of cooking spray.
02 - In a large mixing bowl, whisk together both sugars, vegetable oil, buttermilk, egg, and vanilla until everything is well combined and smooth.
03 - Gently fold in the flour and baking soda, stirring just until the mixture comes together. Don't overmix - a few lumps are perfectly fine.
04 - Add the diced rhubarb to the batter and gently stir until the pieces are evenly distributed throughout. Set the bowl aside while you prepare the topping.
05 - In a small bowl, combine the sugar, cinnamon, and softened butter. Use a fork to mix everything together until it forms a crumbly mixture.
06 - Divide the batter evenly among the muffin cups, filling each about 2/3 full. Sprinkle about 1 teaspoon of the cinnamon topping over each muffin.
07 - Bake for 18-22 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
08 - Let the muffins cool in the pan for about 15 minutes, then transfer them to a wire rack to cool completely before serving.

# Notes:

01 - These muffins are wonderfully moist and have a delightful tangy flavor from the fresh rhubarb that pairs beautifully with the sweet cinnamon topping.
02 - If you don't have buttermilk on hand, simply add 1 tablespoon of white vinegar to a measuring cup and fill with regular milk to the 1-cup mark. Let it sit for a few minutes before using.
03 - Fresh rhubarb works best for this recipe, but make sure to dice it into small, uniform pieces so it distributes evenly throughout the batter.
