Sweet Strawberry Rhubarb Muffins with Streusel Topping

Finding a muffin recipe that truly celebrates spring flavors without being too complicated can feel impossible. Most recipes either skimp on the fruit or require so many steps that you end up spending your entire Saturday morning in the kitchen, and let’s be honest, nobody has time for that when the weather finally gets nice.

Luckily, these strawberry rhubarb muffins with streusel topping hit all the right notes: they’re packed with fresh fruit, feature a buttery crumb topping that adds just the right amount of crunch, and come together in about an hour from start to finish.

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 can range from deep red to pale green, and while the red stalks look prettier, the green ones are just as tasty and will work perfectly fine in this recipe. Make sure to trim off any leaves if they’re still attached, as they’re not edible, and cut your rhubarb into small pieces about the size of your strawberry chunks so everything bakes evenly. If you can only find frozen rhubarb, that’ll work too – just don’t thaw it before adding it to your batter, or it’ll release too much moisture and make your muffins soggy.

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: If rhubarb isn’t in season or you can’t find it, you can use all strawberries instead (2 cups total). You could also try cranberries or raspberries mixed with the strawberries for a tart kick.
• Walnuts: Not a fan of walnuts? Pecans work great in both the muffins and streusel topping. You can also use sliced almonds or just leave them out completely if you have nut allergies.
• Milk: Any milk works here – whole, 2%, almond, oat, or soy milk will all do the job. If using non-dairy milk, the muffins might be slightly less rich but still tasty.
• Butter: You can swap butter for coconut oil or vegetable oil in equal amounts. For the streusel, cold coconut oil works best to get that crumbly texture.
• Brown sugar: If you’re out of brown sugar for the streusel, regular white sugar works fine. You’ll lose a tiny bit of that molasses flavor, but it won’t make a huge difference.

Watch Out for These Mistakes While Baking

The biggest mistake when baking with rhubarb is forgetting that it releases a lot of moisture during baking, which can make your muffins dense and wet – to avoid this, cut the rhubarb into small pieces and toss it with a tablespoon of flour before folding it into the batter.

Starting at the high temperature of 425°F is important for getting those nice domed tops, but keep a close eye on the streusel topping after 12 minutes since it can burn quickly with the butter and sugar.

Don’t overmix the batter once you add the wet ingredients to the dry – stop mixing as soon as you don’t see any more dry flour, because overworking the batter will give you tough, chewy muffins instead of tender ones.

Finally, resist cutting into these muffins right away, as letting them cool for at least 10 minutes helps them firm up and prevents them from falling apart when you peel off the liner.

What to Serve With Strawberry Rhubarb Muffins?

These muffins are perfect for a weekend brunch spread alongside scrambled eggs, crispy bacon, and fresh fruit salad. I love serving them warm with a pat of butter melting on top and a hot cup of coffee or tea on the side. They also make a great afternoon snack with a glass of cold milk or some vanilla yogurt for dipping. If you’re hosting a brunch, set out some whipped cream cheese or honey butter so everyone can customize their muffins however they like.

Storage Instructions

Store: Keep your muffins in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. The streusel topping stays nice and crunchy when stored properly, though it might soften slightly in the fridge.

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

Enjoy: Thaw frozen muffins overnight in the fridge or at room temperature for about an hour. If you want that fresh-baked feel, warm them in a 300°F oven for 5-10 minutes or microwave for 15-20 seconds.

• Calories: 2900-3200
• Protein: 40-50 g
• Fat: 125-140 g
• Carbohydrates: 420-460 g

Ingredients

For the topping:

• 4 tsp flour (I always use King Arthur all-purpose flour)
• 2 tbsp sugar
• 1/2 tbsp brown sugar
• 1 tbsp butter (cold and cubed for a crumblier texture)
• 1/2 pinch salt
• 1/4 cup walnuts

For the batter:

• 1 1/3 cups flour
• 1 1/2 tsp baking powder
• 1 1/4 tsp salt
• 1 cup sugar
• 7 tbsp butter (I like Kerrygold unsalted butter for this)
• 2 eggs (room temperature, about 70°F)
• 1/2 cup milk
• 1 tsp vanilla extract
• 1/2 cup walnuts (finely chopped, about 1/4-inch pieces)
• 1 cup strawberries (hulled and diced into 1/2-inch pieces)
• 1 cup rhubarb

Step 1: Make the Streusel Topping

• 4 tsp flour
• 2 tbsp sugar
• 1/2 tbsp brown sugar
• 1 tbsp cold butter
• 1/2 pinch salt
• 1/4 cup walnuts

Combine the flour, sugar, brown sugar, and salt in a food processor and pulse briefly.

Add the cold cubed butter and pulse until the mixture resembles coarse breadcrumbs with some pea-sized pieces remaining—this texture is key for a crumbly, delicious topping.

Add the walnuts and pulse just until combined.

Transfer to a small bowl and set aside.

I always use cold butter cubed right from the fridge because it creates those desirable larger crumbs that don’t disappear into the batter during baking.

Step 2: Prep the Oven and Prepare Fruit

• 1 cup strawberries
• 1 cup rhubarb

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

While the oven heats, hull and dice the strawberries into roughly 1/2-inch pieces and chop the rhubarb into similar-sized pieces.

Toss the fruit together in a small bowl and set aside—keeping them separate until the last minute prevents excess moisture from accumulating and making the batter soggy.

Step 3: Create the Dry Ingredient Mixture

• 1 1/3 cups flour
• 1 1/2 tsp baking powder
• 1 1/4 tsp salt

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

This combines your leavening agents evenly throughout and helps the muffins rise uniformly and have an even crumb structure.

Step 4: Cream Butter and Sugar, Then Add Eggs and Milk

• 1 cup sugar
• 7 tbsp butter
• 2 eggs
• 1/2 cup milk
• 1 tsp vanilla extract

In a large bowl, beat together the softened butter and sugar until light and fluffy, about 2-3 minutes—this incorporates air and creates a tender crumb in the final muffins.

Add the room-temperature eggs one at a time, beating well after each addition.

Pour in the milk and vanilla extract and stir until just combined.

The batter should be smooth and homogeneous at this point.

Step 5: Combine Wet and Dry Ingredients, Then Add Fruit and Nuts

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

Pour the dry ingredient mixture from Step 3 into the wet mixture from Step 4 and fold gently with a rubber spatula until just combined—do not overmix, as this can create tough muffins.

Once the dry ingredients are barely incorporated, fold in the chopped walnuts and then gently fold in the fruit from Step 2.

I like to add the fruit last and fold gently so the pieces stay intact and distribute evenly throughout rather than sinking to the bottom.

Step 6: Fill Muffin Cups and Add Streusel Topping

• muffin batter from Step 5
• streusel topping from Step 1

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

Sprinkle approximately 1 tablespoon of the streusel topping from Step 1 over each muffin, pressing gently so it adheres to the batter without sinking in.

Step 7: Bake and Cool

Bake at 425°F for 15-18 minutes, until a toothpick inserted into the center of a muffin comes out with just a few moist crumbs (not wet batter).

The tops should be golden brown and the streusel should be toasted.

Allow the muffins to cool in the tin for 10 minutes, then transfer them to a wire rack to cool completely.

This resting time in the tin allows the muffins to set slightly so they don’t fall apart when you remove them.
