Ingredients
Muffin Batter
- 1/2 cup vegetable oil
- 1 cup granulated sugar
- 2 large eggs
- 1 1/2 cups whole milk
- 2 tsp vanilla extract
- 2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 2 3/4 cups all purpose flour
- 2 cups rhubarb, thinly sliced
Streusel Topping
- 1/4 cup all purpose flour
- 2 Tbsp granulated sugar
- 1 Tbsp unsalted butter, at room temperature
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 12-cup muffin pan with paper muffin liners to prevent sticking and make cleanup easier.
- Make Streusel: In a small bowl, combine 1/4 cup flour, 2 tablespoons sugar, and 1 tablespoon room-temperature unsalted butter. Rub the mixture together with your fingers until the butter is fully incorporated and the mixture forms a dry, crumbly texture. Set this streusel aside while you make the batter.
- Mix Wet Ingredients: In a large mixing bowl, whisk together the vegetable oil, granulated sugar, eggs, whole milk, and vanilla extract until smooth and well combined.
- Add Leavening and Salt: Add the baking powder, baking soda, and salt to the wet ingredients. Whisk well to incorporate everything evenly.
- Add Flour and Rhubarb: Whisk in the 2 3/4 cups of all-purpose flour until just combined. Then gently fold in the thinly sliced rhubarb, taking care not to overmix to keep the muffins tender.
- Fill Muffin Cups: Evenly divide the batter between the 12 muffin cups, filling each about 2/3 full. This ensures the muffins have room to rise without overflowing.
- Top with Streusel: Sprinkle the prepared streusel topping evenly over each muffin for a sweet, crumbly finish.
- Bake: Bake in the preheated oven for 23-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean and the tops are golden brown.
- Serve: Remove from oven and allow to cool slightly. Serve the muffins warm, optionally with butter spread on top for extra richness.
Notes
- You can substitute buttermilk for whole milk with 1/2 teaspoon baking soda adjustment if desired, to enhance the tender crumb and tangy flavor.
- Be careful not to overmix the batter once the flour is added to avoid tough muffins.
- Make sure rhubarb is chopped thinly so it cooks evenly and releases its tart flavor without excess moisture.
- The streusel topping can be made ahead and refrigerated until you are ready to bake.
- If you don’t have paper liners, grease your muffin tin well to prevent sticking.
