Simple Strawberry Rhubarb Muffins

Spring baking is my favorite kind of baking. I get excited when I see the first stalks of rhubarb at the farmers market, knowing strawberries aren’t far behind. The two together make the perfect sweet-tart combo that I can’t get enough of. And honestly, I’d rather turn them into muffins than pie any day.

Why muffins? They’re easier, for one. No rolling out dough or crimping edges. Just mix, scoop, and bake. Plus, they’re portable. My kids can grab one on the way out the door, and I can pack them in lunches without worrying about them falling apart.

These muffins have a little crumbly walnut topping that adds a nice crunch. Want to skip the nuts? Go ahead. Want to use all strawberries or all rhubarb? That works too. I make these whenever I need something that feels special but doesn’t require me to be a pastry chef.

What Kind of Rhubarb Should I Use?

Fresh rhubarb is always your best bet for these muffins, and you’ll find it in season during spring and early summer at most grocery stores and farmers markets. The color of the stalks doesn’t really matter – red rhubarb looks pretty, but green rhubarb tastes just as good and will work perfectly fine in this recipe. If you can’t find fresh rhubarb, frozen rhubarb is a solid backup option, just make sure to thaw it completely and pat it dry with paper towels to remove excess moisture before mixing it into your batter. When you’re prepping your rhubarb, remember to trim off and discard the leaves since they’re toxic, and cut the stalks into small pieces about the size of your strawberry chunks so everything bakes evenly.

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 is best here, but if it’s out of season, frozen rhubarb works too. Just thaw it first and pat it dry with paper towels to remove excess moisture before folding it into the batter.
• Strawberries: You can use frozen strawberries if fresh aren’t available – same deal as the rhubarb, thaw and pat dry first. Or try swapping them out for blueberries or raspberries for a different flavor combo.
• Walnuts: Not a fan of walnuts? Pecans or almonds work great as substitutes. You can also leave them out completely if you have nut allergies or just prefer your muffins without them.
• Milk: Any milk works here – whole, 2%, almond, oat, or soy milk are all fine. Just stick with whatever you normally keep in your fridge.
• Butter: You can swap butter for vegetable oil or melted coconut oil if needed. Use the same amount, but note that oil will make the muffins slightly more moist and less rich-tasting.
• Brown sugar: If you’re out of brown sugar for the topping, just use regular white sugar instead. You’ll lose a tiny bit of that caramel flavor, but the muffins will still taste great.

Watch Out for These Mistakes While Baking

The biggest mistake when making strawberry rhubarb muffins is overmixing the batter once you add the dry ingredients to the wet – mix just until combined, even if you see a few lumps, because overmixing leads to tough, dense muffins instead of light and fluffy ones.

Another common error is cutting your strawberries and rhubarb too large, which creates air pockets and uneven baking, so dice them into small, uniform pieces about 1/4 to 1/2 inch in size.

Don’t skip tossing your fruit in a tablespoon of flour before folding it into the batter, as this prevents the strawberries and rhubarb from sinking to the bottom and releasing too much moisture.

Finally, resist the urge to open the oven door during the first 12 minutes of baking – the temperature drop can cause your muffins to collapse and lose their nice domed tops.

What to Serve With Strawberry Rhubarb Muffins?

These muffins are perfect for breakfast or brunch alongside a hot cup of coffee or tea. I love serving them with a simple fruit salad made with fresh berries and melon, which complements the strawberry-rhubarb flavor without being too heavy. They’re also great with a dollop of Greek yogurt or a smear of cream cheese if you want something a bit richer. For a complete brunch spread, pair them with scrambled eggs and crispy bacon to balance out the sweetness of the muffins.

Storage Instructions

Store: Keep your strawberry rhubarb muffins in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. The fruit keeps them pretty moist, so they actually taste great even a few days later!

Freeze: These muffins freeze really well for up to 3 months. Just let them cool completely, then wrap each one individually in plastic wrap before putting them all in a freezer bag. This way you can grab just one or two whenever you want a quick breakfast or snack.

Thaw: To enjoy a frozen muffin, just leave it on the counter for about an hour to thaw at room temperature. If you’re in a hurry, pop it in the microwave for 20-30 seconds. I like to warm mine up slightly in the microwave even when they’re not frozen – it makes them taste freshly baked!

• Calories: 2650-2850
• Protein: 40-46 g
• Fat: 110-120 g
• Carbohydrates: 380-410 g

Ingredients

For the topping:

• 1.5 tbsp flour
• 2.5 tbsp sugar
• 1 tbsp brown sugar (I prefer C&H golden brown sugar)
• 1.5 tbsp butter (cold, cut into small pea-sized cubes)
• 1/4 cup walnuts (finely chopped, about 1/8-inch pieces)
• 1 pinch salt

For the muffin batter:

• 1 1/2 cups flour (I always use King Arthur all-purpose flour)
• 1.25 cups sugar
• 8 tbsp butter (melted and cooled to room temperature)
• 2 eggs (large, at room temperature)
• 1/2 cup milk
• 2 tsp baking powder
• 1 tsp salt
• 1 cup strawberries (hulled and diced into 1/2-inch pieces)
• 1 cup rhubarb (sliced into 1/2-inch thick pieces)
• 1/2 cup walnuts
• 1/2 tsp vanilla extract

Step 1: Prepare the Streusel Topping

• 1.5 tbsp flour
• 2.5 tbsp sugar
• 1 tbsp brown sugar
• 1 pinch salt
• 1.5 tbsp butter
• 1/4 cup walnuts

In a food processor, combine the flour, sugar, brown sugar, and salt, then pulse until the mixture resembles coarse sand.

Add the cold butter cubes and pulse until the mixture forms pea-sized crumbs—this creates a tender, crumbly texture that won’t be dense.

Pulse in the finely chopped walnuts until just combined, then transfer to a small bowl and set aside.

The cold butter is key here; it prevents the topping from becoming too compact and gives you those desirable rustic crumbles.

Step 2: Prepare Fruit and Preheat

• 1 cup strawberries
• 1 cup rhubarb

While the streusel sets aside, hull and dice the strawberries into 1/2-inch pieces and slice the rhubarb into 1/2-inch thick pieces—this uniform sizing ensures even cooking throughout the muffins.

Preheat your oven to 425°F and line your muffin pan with paper liners.

I find that prepping the fruit now, while the oven heats, keeps the workflow smooth and prevents any fruit from oxidizing or breaking down.

Step 3: Combine Dry Ingredients

• 1 1/2 cups flour
• 2 tsp baking powder
• 1 tsp salt

In a medium bowl, whisk together the flour, baking powder, and salt.

This step aerates the dry ingredients and distributes the leavening evenly, which helps the muffins rise uniformly and achieve a tender crumb.

Step 4: Create the Wet Base

• 8 tbsp butter
• 1.25 cups sugar
• 2 eggs
• 1/2 cup milk
• 1/2 tsp vanilla extract

In a separate bowl, whisk together the melted butter and sugar until combined, then add the eggs one at a time, whisking well after each addition to create an emulsion.

Pour in the milk and vanilla extract, whisking until smooth and fully incorporated.

Using room-temperature eggs and cooled melted butter ensures they combine smoothly without creating lumps or separating.

Step 5: Combine Batters and Fold in Fruit

• dry ingredient mixture from Step 3
• wet ingredient mixture from Step 4
• 1/2 cup walnuts
• prepared strawberries from Step 2
• prepared rhubarb from Step 2

Pour the wet mixture from Step 4 into the dry mixture from Step 3 and stir gently with a spatula until just combined—do not overmix, as this will develop gluten and make the muffins tough.

Fold in the walnuts, strawberries, and rhubarb using as few strokes as possible, being careful not to crush the fruit.

The batter should look slightly lumpy rather than smooth.

Step 6: Fill and Top Muffins

• batter from Step 5
• streusel topping from Step 1

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

Generously top each muffin with the streusel topping from Step 1, pressing it down very gently so it adheres but doesn’t compact.

The generous topping creates that signature crumbly texture that makes these muffins special.

Step 7: Bake and Cool

Bake at 425°F for 15–18 minutes, until the muffin tops are golden and a toothpick inserted into the center of a muffin (avoiding the fruit) comes out clean.

Allow the muffins to cool in the pan for 10 minutes to set slightly, then transfer to a wire cooling rack.

This cooling-in-pan step allows the structure to stabilize so the muffins hold their shape when moved.
