Tasty Rhubarb Streusel Muffins

If you ask me, rhubarb muffins are even better with a sweet, crumbly topping.

These streusel-topped treats combine tart spring rhubarb with a buttery, tender muffin base. The crunchy brown sugar topping adds just the right amount of sweetness to balance out the natural tanginess of the rhubarb.

Fresh chunks of rhubarb folded into the simple batter create little pockets of flavor throughout each muffin. A hint of vanilla and cinnamon in the background ties everything together.

They’re perfect for breakfast or afternoon snacks, and they’ll make your kitchen smell like a neighborhood bakery while they’re in the oven.

What Kind of Rhubarb Should I Use?

When shopping for rhubarb, you’ll find both green and red varieties at the store – and either one will work perfectly in these muffins. The color doesn’t affect the taste, though the red stalks tend to make prettier baked goods. Look for stalks that are firm and crisp, avoiding any that are limp or have blemishes. For the best results, choose stalks that are about 1-inch thick, as super thick ones can be tough and stringy while very thin ones might cook down too quickly. Remember to only use the stalks since rhubarb leaves are not edible. If you’re using frozen rhubarb, thaw and drain it well before adding it to your muffin batter to prevent excess moisture.

Options for Substitutions

Let’s talk about what you can swap in this muffin recipe if you’re missing something:

• Rhubarb: If fresh rhubarb isn’t in season, you can use frozen rhubarb (just thaw and drain well first). You could also try tart apples or cranberries for a similar tangy taste.
• Vegetable oil: Any neutral oil works here – try canola, sunflower, or even melted coconut oil. You can also use melted butter for a richer taste.
• Walnuts: Feel free to swap these with pecans, almonds, or any other nuts you have on hand. If you need to avoid nuts, just leave them out or add some oats to the streusel for crunch.
• Milk: Any milk works fine – dairy or non-dairy options like almond, soy, or oat milk will all do the job. For the glaze, you might need to adjust the amount slightly with non-dairy alternatives.
• Plain flour: While regular plain flour works best here, you can use self-rising flour – just skip the baking powder and salt if you do. For the streusel, whole wheat flour can work too.
• Powdered sugar: If you’re out of powdered sugar for the glaze, you can make your own by blending regular sugar in a food processor until very fine.

Watch Out for These Mistakes While Baking

The biggest mistake when making rhubarb muffins is overmixing the batter – stop stirring as soon as the dry ingredients are just incorporated, as overmixing will lead to dense, tough muffins instead of light and tender ones. A common error with rhubarb is not chopping it finely enough, which can result in hard, fibrous chunks that affect the texture – aim for pieces no larger than 1/4 inch for the best eating experience. For the streusel topping, using warm or room-temperature butter instead of cold butter will give you a paste rather than the desired crumbly texture, so make sure to keep your butter chilled until the moment you need it. To ensure even baking, avoid overfilling your muffin cups – fill them only 2/3 full, as this gives the muffins room to rise without spilling over the edges.

What to Serve With Rhubarb Muffins?

These sweet and tangy muffins make a perfect breakfast or brunch treat, and they pair wonderfully with a hot cup of coffee or tea. For a more filling breakfast spread, serve them alongside some fresh fruit and yogurt – berries work especially well since they complement the tartness of the rhubarb. If you’re hosting a brunch, these muffins go great with savory dishes like scrambled eggs or a breakfast casserole to balance out the sweetness. You can also warm them up slightly and spread some butter or cream cheese on top for an extra special touch.

Storage Instructions

Counter Storage: These rhubarb streusel muffins stay fresh at room temperature for up to 2 days. Just keep them in an airtight container and they’ll maintain their lovely texture. If your kitchen is warm, it’s better to pop them in the fridge instead.

Refrigerate: Want to keep your muffins longer? Store them in the fridge in a sealed container for up to 5 days. The streusel topping might soften a bit, but they’ll still taste great. I like to place a paper towel in the container to absorb any extra moisture.

Freeze: These muffins freeze really well for up to 3 months. Let them cool completely, then wrap each one individually in plastic wrap and place them in a freezer bag. When you’re ready for a muffin, just thaw it overnight in the fridge or for about an hour on the counter.

Ingredients

For the muffins:

• 2 tsp baking powder
• 1 cup chopped rhubarb (cut into 1/2-inch pieces)
• 1 large egg
• 1/3 cup milk (whole milk gives better texture)
• 1/2 tsp salt
• 1 1/2 cups all-purpose flour (I always use King Arthur all-purpose flour)
• 3/4 cup granulated sugar
• 1/3 cup vegetable oil (or any other neutral oil like canola)

For the streusel topping:

• 1/2 cup granulated sugar
• 1/4 cup chopped walnuts (optional, adds a nice crunch)
• 1 tsp ground cinnamon
• 1/4 cup cold unsalted butter (I like Kerrygold unsalted butter for this)
• 1/3 cup all-purpose flour

For the glaze:

• 2 tbsp milk
• 1 cup powdered sugar

Step 1: Prepare the Oven and Muffin Tin

Preheat your oven to 375 degrees F.

Line a muffin tin with paper liners to prevent sticking and make cleanup easy.

Set the prepared muffin tin aside for later use.

Step 2: Mix Dry and Wet Ingredients Separately

In a large mixing bowl, whisk together the flour, sugar, salt, and baking powder to evenly distribute the dry ingredients.

In another bowl, whisk together the egg, oil, and milk until well combined to create the wet mixture.

Step 3: Combine the Mixtures and Prepare the Batter

Pour the wet mixture into the bowl with the dry ingredients.

Stir until just combined, being careful not to overmix.

Add the rhubarb and gently fold it into the muffin batter.

Evenly divide the batter among the twelve prepared muffin liners in the muffin tin.

Set aside.

Step 4: Prepare and Add the Streusel Topping

In a small bowl, use a fork to smash together the first four ingredients of the streusel topping until it looks lumpy and coarse.

Toss in the chopped walnuts and mix gently.

Evenly distribute the streusel topping over the muffins, pressing lightly.

If desired, add finely diced rhubarb on top of the streusel for extra rhubarb flavor.

Step 5: Bake and Cool the Muffins

Bake the muffins in the preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Allow the muffins to cool for about 5 minutes in the muffin tin before transferring them to a wire baking rack to cool completely.

Step 6: Glaze and Store the Muffins

Once cooled, whisk together the glaze ingredients and drizzle the desired amount over each muffin.

Serve the muffins as a delightful treat.

Store any leftovers in an air-tight container or in a domed cake stand to keep them fresh for up to 3 days.
