Classic Rhubarb Crisp Muffins

Here is my favorite rhubarb crisp muffin recipe, with a mix of whole wheat and all-purpose flour, tangy rhubarb pieces, and a crunchy oat and cinnamon topping that tastes just like a fruit crisp.

These muffins are perfect for spring mornings when rhubarb is in season. I love making a batch on Sunday so the kids can grab one for breakfast during the week. Nothing better than a warm muffin with a cup of coffee, right?

What Kind of Rhubarb Should I Use?

Fresh rhubarb is always your best bet for these muffins, and you’ll find it in grocery stores during spring and early summer when it’s in season. The color of the stalks – whether they’re bright red, pink, or greenish – doesn’t really affect the flavor, so grab whatever looks fresh and firm. If you can’t find fresh rhubarb, frozen works just fine too, but make sure to thaw it completely and drain off any excess liquid before chopping it up for your muffins. Just remember to always trim off and discard the leaves if you’re using rhubarb from your garden, as they’re toxic and only the stalks are edible.

Options for Substitutions

These muffins are pretty forgiving when it comes to swaps, so here are some options if you need to make changes:

• Rhubarb: Fresh rhubarb works best, but frozen rhubarb is totally fine – just thaw it first and drain any excess liquid. You could also try diced apples or strawberries for a different flavor, though the tartness won’t be quite the same.
• Whole wheat flour: If you don’t have whole wheat flour, just use all-purpose flour for the full amount. You can also try white whole wheat flour for a lighter texture while keeping some whole grain goodness.
• Vanilla yogurt: Plain yogurt or Greek yogurt work great – just add a splash of vanilla extract. Sour cream is another option, though it’ll make the muffins a bit richer.
• Brown sugar: White sugar works in a pinch, though you’ll lose that slight molasses flavor. You could also use coconut sugar or maple sugar for a different twist.
• Oil: Melted butter, melted coconut oil, or even applesauce can replace the oil. If using applesauce, your muffins will be a bit denser but still tasty.
• Oats: The oats in the topping can be swapped with chopped nuts like pecans or almonds, or you can use more flour if you need a nut-free option.

Watch Out for These Mistakes While Baking

The biggest mistake when baking with rhubarb is not cutting it into small, uniform pieces – chunks that are too large won’t cook through properly and can make your muffins watery, so aim for 1/2-inch pieces.

Overmixing the batter once you combine the wet and dry ingredients will result in tough, dense muffins instead of light and tender ones, so stir just until the flour disappears and a few lumps remain.

Don’t skip the step of letting the muffins cool in the pan for the full 15 minutes, as rhubarb muffins are more delicate than regular muffins and need this time to set up properly before you try to remove them.

For an extra tip, if your rhubarb is particularly tart, toss it with a tablespoon of sugar before adding it to the batter to balance out the flavors without making the muffins overly sweet.

What to Serve With Rhubarb Crisp Muffins?

These muffins are perfect for breakfast or brunch alongside a hot cup of coffee or tea. I love serving them warm with a pat of butter that melts right into all those crispy, oaty nooks and crannies on top. They also pair really well with Greek yogurt and fresh berries for a more filling breakfast, or you can enjoy them as an afternoon snack with a glass of cold milk. If you’re hosting brunch, set these out with scrambled eggs and bacon for a sweet-and-savory spread that everyone will love.

Storage Instructions

Store: Keep your rhubarb crisp muffins in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. The crisp topping might soften a bit in the fridge, but they’ll still taste great for breakfast or a snack throughout the week.

Freeze: These muffins are perfect for freezing! Let them cool completely, then wrap each one individually in plastic wrap and store in a freezer bag for up to 3 months. It’s nice to have them ready to grab for busy mornings.

Thaw: Just leave a frozen muffin on the counter for about an hour to thaw at room temperature, or pop it in the microwave for 20-30 seconds. You can also warm them in the oven at 350°F for about 10 minutes if you want that fresh-baked feel again.

Ingredients

For the muffins:

• 1 1/4 cup rhubarb (sliced into 1/2-inch pieces)
• 3/4 cup brown sugar
• 2/3 cup flour (I always use King Arthur all-purpose flour)
• 2/3 cup whole wheat flour
• 3/4 tsp cinnamon
• 1/2 tsp baking soda
• 3/4 tsp salt
• 1/2 cup vanilla yogurt (I prefer Stonyfield organic for extra creaminess)
• 1/4 cup oil
• 1 egg (room temperature, about 70°F)

For the topping:

• 1/4 cup brown sugar
• 1/4 cup oats (I like Quaker old-fashioned oats for better texture)
• 3 tbsp butter (cold and cut into 1/4-inch cubes)
• 3/4 tsp cinnamon

Step 1: Prepare Equipment and Make the Crisp Topping

• 1/4 cup brown sugar
• 1/4 cup oats
• 3/4 tsp cinnamon
• 3 tbsp butter

Preheat your oven to 350°F and line a 12-cup muffin pan with paper liners.

While the oven heats, prepare the crisp topping by combining the brown sugar, oats, cinnamon, and cold butter cubes in a small bowl.

Use your fingertips to rub the butter into the dry ingredients until the mixture resembles coarse breadcrumbs with some pea-sized pieces of butter remaining—this creates the texture that makes the crisp topping crispy and buttery.

Set aside until ready to use.

Step 2: Combine Dry Ingredients and Prepare Rhubarb Base

• 1 1/4 cup rhubarb
• 3/4 cup brown sugar
• 2/3 cup flour
• 2/3 cup whole wheat flour
• 3/4 tsp cinnamon
• 1/2 tsp baking soda
• 3/4 tsp salt

In a large mixing bowl, whisk together both flours, 3/4 teaspoon cinnamon, baking soda, and salt.

Add the sliced rhubarb and 3/4 cup brown sugar to the dry mixture, gently folding everything together with a spatula.

The rhubarb should be evenly coated with the dry ingredients—this helps distribute it throughout the muffins and prevents it from sinking to the bottom.

Step 3: Mix Wet Ingredients and Create the Batter

• 1 egg
• 1/2 cup vanilla yogurt
• 1/4 cup oil
• dry ingredient mixture from Step 2

In a separate bowl, whisk together the room-temperature egg, yogurt, and oil until well combined and the egg is fully incorporated.

I find that using room-temperature eggs helps them blend more smoothly with the other wet ingredients.

Pour the wet mixture into the dry rhubarb mixture and gently stir with a spatula until just combined—stop as soon as you don’t see streaks of flour.

Overmixing will develop gluten and make the muffins tough, so restraint is key here.

Step 4: Fill Muffin Cups and Top with Crisp Mixture

• muffin batter from Step 3
• crisp topping from Step 1

Divide the batter evenly among the 12 lined muffin cups, filling each about two-thirds full.

Top each muffin with approximately 1 tablespoon of the crisp topping from Step 1, distributing it evenly across the surface.

Don’t press it down—let it sit loosely on top so it stays crispy and doesn’t sink into the batter during baking.

Step 5: Bake and Cool

Bake in the preheated 350°F oven for 20 minutes, until the tops are golden brown and a toothpick inserted into the center of a muffin comes out with just a few moist crumbs.

Allow the muffins to cool in the pan for 15 minutes before removing them from the liners—this resting time lets them set and makes them easier to handle without falling apart.
