Every ingredient in these muffins plays a starring role—let’s break down what you need and why.
- 1 1/2 cups rolled oats: Wholesome flakes that add texture and boost fiber for a hearty breakfast muffin.
- 3/4 cup whole wheat flour: Brings nuttiness and extra nutrients for a more wholesome crumb.
- 3/4 cup all-purpose flour: Balances structure with lightness to keep muffins tender.
- 2 teaspoons baking powder: Provides lift and a fluffy, well-risen top.
- 1/2 teaspoon baking soda: Reacts with rhubarb’s natural acidity for a tender crumb.
- 1/4 teaspoon salt: Enhances all flavors and balances sweetness.
- 1/3 cup brown sugar: Adds mild molasses notes and helps retain moisture.
- 1 cup milk: Hydrates dry ingredients and creates a smooth batter.
- 1 large egg: Binds ingredients and gives structure while adding richness.

How To Make Rhubarb Oat Muffin
Baking these muffins is straightforward and fun—just mix, fold, and bake! You’ll start by preparing your dry and wet mixes separately, then gently bring them together before folding in those vibrant rhubarb pieces. Follow the steps below to achieve moist, golden muffins every time.
1. Preheat the oven to 400°F and line a 12-cup muffin pan with paper liners or grease each cup thoroughly to prevent sticking.
2. In a large bowl, whisk together the rolled oats, whole wheat flour, all-purpose flour, baking powder, baking soda, salt, and brown sugar until uniformly combined.
3. In a separate bowl, lightly beat the large egg, then stir in the milk, melted butter, and vanilla extract until the mixture is smooth and cohesive.
4. Pour the wet ingredients into the dry ingredients and stir until just combined, being careful not to overmix so the muffins stay tender.
5. Gently fold the chopped rhubarb into the batter with a spatula, distributing the tart pieces evenly without breaking them down.
6. Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full for perfect dome shape.
7. Bake for 18 to 20 minutes or until the tops turn golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
8. Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely and set their crumb.

Tips For Perfect Rhubarb Oat Muffin
Want to nail these muffins every single time? I’ve tested this recipe in winter and spring kitchens, and these simple tweaks make a big difference. Keep your batter just mixed enough for a tender crumb, and don’t shy away from playing with moisture or sweetness levels based on your taste.
- You can substitute plain yogurt for part of the milk to add extra moisture and a slight tang to your muffins.
- For a sweeter muffin, swap the brown sugar for granulated sugar or increase it by up to 2 tablespoons.
- Store freshly baked muffins in an airtight container at room temperature for up to two days to maintain that soft crumb.
- Leftover muffins freeze well for up to one month when wrapped tightly—just thaw or reheat before serving.
How To Store It
Keeping your muffins fresh and flavorful is easy when you follow a few simple storage tips. Whether you plan to enjoy them over the next couple of days or save some for future breakfasts, these methods will maintain their tender crumb and golden tops.
- Room Temperature: Once completely cool, place muffins in an airtight container with a piece of parchment or paper towel between layers to absorb moisture. Enjoy within two days.
- Freezer: Wrap each muffin individually in plastic wrap or aluminum foil, then store in a freezer-safe bag or container for up to one month.
- Thawing: Remove from freezer, unwrap, and let sit at room temperature for about an hour, or microwave on low power for 20–30 seconds until soft.
- Reheating: Warm muffins in a 350°F oven for 5 minutes or microwave briefly to restore a just-baked softness.
Frequently Asked Questions
Here are answers to the most common questions about making and enjoying these muffins:
- Q: How long does it take to prepare this recipe?
A: It takes about 10 minutes to gather and measure ingredients, 5 minutes to mix the dry ingredients and another 5 minutes to combine wet and dry ingredients and fold in the rhubarb, for a total of about 20 minutes prep time, plus 18 to 20 minutes baking and a few minutes cooling.
- Q: Can I substitute plain yogurt for part of the milk?
A: Yes. You can replace up to half of the milk with plain yogurt to add extra moisture and a slight tang. If you use yogurt, stir it in with the wet ingredients and the texture will be tenderer, though you may need to add a splash more milk if the batter becomes too thick.
- Q: What types of flour work best for these muffins?
A: The recipe calls for ¾ cup whole wheat flour for nuttiness and ¾ cup all-purpose flour for lightness. You can swap part of the all-purpose flour for whole wheat pastry flour for a softer texture, but avoid using only whole wheat flour or gluten-free flour blends without adjusting the liquid, as the oats and rhubarb already absorb moisture.
- Q: How do I know when the muffins are done baking?
A: The muffin tops should be golden brown and spring back slightly when touched. Insert a toothpick into the center of a muffin—if it comes out clean or with a few moist crumbs, they are done. Baking times can vary by oven, so check at 18 minutes and add up to 2 more if needed.
- Q: How should I store leftover muffins and how long will they keep?
A: Store cooled muffins in an airtight container at room temperature for up to two days. To extend freshness, place a piece of paper towel in the container to absorb excess moisture. For longer storage, freeze as described below.
- Q: Can I freeze these muffins, and how should I thaw them?
A: Yes. Once completely cooled, wrap each muffin tightly in plastic wrap and place in a freezer-safe bag or container for up to one month. To thaw, remove wrappers and let muffins sit at room temperature for about an hour, or microwave on low power for 20–30 seconds until soft.
- Q: How can I make the muffins sweeter or add extra flavor?
A: For sweeter muffins, swap the brown sugar for granulated sugar or increase the sugar by 2 tablespoons. You can also add a teaspoon of cinnamon or a zest of orange to the dry mix. Stir in half a cup of chopped strawberries or blueberries with the rhubarb for a fruitier twist.
