Ingredients

For the Cinnamon Butter Crumble
- ¼ cup unsalted butter (chilled and cut into 1/4 pieces)
- ¼ cup unbleached all-purpose flour
- ¼ cup old-fashioned oats
- 2 tbsp brown sugar
- 1 tsp ground cinnamon
- 1 tsp turbinado sugar (optional – sugar in the raw)
For the Muffins
- 2½ cups unbleached all-purpose flour
- 1¼ cups brown sugar (I used dark brown sugar but either is fine)
- 1 cup old-fashioned oats
- 1 tsp baking soda
- 1 tsp salt
- 1 tsp cinnamon
- 1 cup whole milk
- 1 tsp white vinegar (or lemon juice)
- 1 tsp vanilla extract
- ½ cup vegetable oil (or canola)
- 1 egg (lightly beaten)
- 2 cups rhubarb (chopped – reserve 1/4 cup for topping)
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: Prepare the Cinnamon Butter Crumble
In a small bowl, combine crumble ingredients:
1. Add the chilled butter pieces to flour, oats, brown sugar, and cinnamon.
2. Use two forks or a pastry cutter to mix until it resembles coarse crumbs. If needed, refrigerate if the butter gets too warm.
Step 3: Mix Dry Ingredients for Muffins
In a large mixing bowl:
1. Combine flour, brown sugar, oats, baking soda, salt, and cinnamon.
2. Whisk together until evenly mixed.
Step 4: Combine Wet Ingredients
In another medium bowl:
1. Mix milk, vinegar (or lemon juice), vanilla extract, oil, and egg.
2. Whisk together until well combined.
Step 5: Combine Wet and Dry Mixtures
Add the wet ingredients to your dry mixture:
1. Stir gently until just combined; do not overmix.
2. Fold in 1¾ cups of chopped rhubarb gently.
Step 6: Fill Muffin Cups
Fill each muffin cup about halfway to three-quarters full:
1. Top with remaining chopped rhubarb and sprinkle crumble on top.
2. Optionally sprinkle turbinado sugar over the crumble.
Step 7: Bake
Bake in preheated oven for 20 to 25 minutes:
1. Rotate pans halfway through baking.
2. Check doneness by inserting a toothpick into the center; it should come out clean.
Step 8: Cool & Store
Allow muffins to cool in pans for about 10 minutes:
1. Transfer them onto a baking rack to cool completely or serve warm.
2. Store in an airtight container at room temperature or refrigerate. They may also be frozen for longer storage.

Common Mistakes to Avoid
Baking can be tricky, especially with recipes like Rhubarb Oat Muffins with Cinnamon Butter Crumble. Here are some common mistakes to watch out for:
-
Skipping the butter chilling step: If you don’t chill the butter before making the crumble, it may not create that desired crumbly texture. Always remember to keep it cold for optimal results.
-
Overmixing the batter: Mixing too much can lead to dense muffins. Stir just until combined when adding wet ingredients to dry ingredients for light and fluffy muffins.
-
Using fresh rhubarb without preparation: Fresh rhubarb should be chopped and possibly sprinkled with sugar beforehand to reduce tartness. This enhances the flavor balance in your muffins.
-
Not measuring ingredients accurately: Baking is a science. Using improper measurements can throw off the balance of flavors and textures, so always use precise measuring tools.
-
Ignoring baking time: Each oven is different. Trust your toothpick test rather than relying solely on set baking times; this ensures perfectly baked muffins every time.
