- 1 cup old-fashioned oats
- 1 tsp baking soda
- 1 tsp salt
- 1 tsp cinnamon
- 1 cup whole milk

How to Make Rhubarb Oat Muffins with Cinnamon Butter Crumble
Step 1: Preheat the Oven
Preheat your oven to 350 °F. Line two standard muffin pans with cupcake liners or spray them with non-stick cooking spray.
Step 2: Make the Cinnamon Butter Crumble
In a small bowl, combine the crumble ingredients:
1. Add the chilled butter to the flour, oats, brown sugar, and cinnamon.
2. Use two forks or a pastry cutter to mix until it resembles coarse crumbs. If necessary, refrigerate if the butter becomes too soft.
Step 3: Prepare the Muffin Batter
In a large mixing bowl:
1. Combine flour, brown sugar, cinnamon, oats, baking soda, and salt. Whisk together until mixed well.
In another medium bowl:
2. Combine milk, vinegar, vanilla extract, oil, and egg. Whisk until blended.
Step 4: Combine Wet & Dry Ingredients
Add the wet mixture to the dry ingredients:
1. Stir gently until just combined.
2. Fold in 1¾ cups chopped rhubarb carefully to avoid overmixing.
Step 5: Fill Muffin Cups
Fill each muffin cup about halfway to three-quarters full:
1. Top with remaining chopped rhubarb and sprinkle generously with crumble.
2. Optionally sprinkle turbinado sugar on top for extra sweetness.
Step 6: Bake
Bake for 20 to 25 minutes:
1. Rotate pans halfway through baking.
2. Check doneness by inserting a toothpick; it should come out clean.
Step 7: Cool & Store
Allow muffins to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely:
– Store muffins in an airtight container at room temperature or refrigerate for freshness.
– These muffins may also be frozen for later enjoyment!

Common Mistakes to Avoid
Many home bakers make mistakes that can affect the outcome of their Rhubarb Oat Muffins with Cinnamon Butter Crumble. Here are some common pitfalls to watch for.
-
Using warm butter: Softened butter won’t create the right crumble texture. Always use chilled butter cut into small pieces for the best results.
-
Overmixing the batter: Mixing too much can result in dense muffins. Stir the wet and dry ingredients just until combined for a light texture.
-
Skipping the vinegar: The vinegar helps to curdle the milk, creating a buttermilk effect which adds moisture. Don’t skip this step for optimal muffin fluffiness.
-
Not rotating pans: If you don’t rotate your muffin pans halfway through baking, you may end up with unevenly cooked muffins. Always give them a turn for consistent results.
-
Ignoring cooling time: Letting muffins cool in the pan too long can make them soggy. Cool them for just 10 minutes, then transfer to a wire rack.
