Big Buttermilk Strawberry Rhubarb Muffins Ingredients

For the Muffins
• Unsalted Butter (5 tablespoons, melted) – Adds moisture and richness; can be substituted with coconut oil for dairy-free options.
• All-Purpose Flour (2¾ cups total) – Provides structure to the muffins; cake flour may yield a lighter texture.
• Light Brown Sugar (½ cup + 2 tablespoons) – Sweetens the muffins and adds depth; can be replaced with brown sugar or coconut sugar purely for sweetness.
• Fine Sea Salt (¾ teaspoon total) – Enhances flavor; use kosher salt as an alternative.
• Strawberries (8 ounces, hulled and chopped) – Provides sweetness and moisture; frozen strawberries can be used but drain excess liquid.
• Rhubarb (2 stalks, diced, 6-8 ounces) – Contributes tartness and flavor depth; can omit or replace with additional strawberries.
• Cornstarch (¼ cup) – Helps to thicken the fruit mixture and stabilize; can be swapped with arrowroot powder.
• Lemon Juice (1 teaspoon) – Brightens flavors of the muffin; use lime juice for a different citrus note.
• Granulated Sugar (½ cup) – Adds sweetness; can be replaced with an equal amount of honey or agave syrup.
• Baking Powder (1 teaspoon) and Baking Soda (1 teaspoon) – Leavening agents that help muffins rise; ensure both are fresh for best results.
• Egg (1, lightly beaten) – Acts as a binder; a flax egg can be used for a vegan version.
• Canola Oil (¼ cup) – Adds moisture; avocado oil can be used as a healthier alternative.
• Buttermilk (1 cup) – Provides tanginess and tenderness; milk with vinegar or yogurt can serve as substitutes.
• Vanilla Extract (2 teaspoons) – Enhances the flavor profile; almond extract can offer a complementary taste.
• Grated Zest (from 1 orange or lemon) – Adds aromatic citrus notes; omit if not available, but recommended for added flavor.

For the Streusel Topping
• Light Brown Sugar (¼ cup) – Adds sweetness and texture; can be substituted with white sugar if desired.
• All-Purpose Flour (½ cup) – Helps create the streusel’s crumbly consistency; whole wheat flour can add a nutty flavor.

Step‑by‑Step Instructions for Big Buttermilk Strawberry Rhubarb Muffins

Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C) while positioning a rack in the center. Prepare a 6-cup jumbo muffin tin by lining it with parchment liners for easy removal after baking. This initial step ensures your muffins will rise beautifully, creating that perfect dome shape we all love!

Step 2: Make the Streusel Topping
In a mixing bowl, combine the melted butter, flour, brown sugar, and salt. Use a fork or your fingers to mix until the ingredients form large, moist crumbs. Set this delightful streusel aside, as it will add a rich, sweet crunch to your Big Buttermilk Strawberry Rhubarb Muffins once baked.

Step 3: Prepare the Fruit Filling
In a separate bowl, gently mix the chopped strawberries, diced rhubarb, cornstarch, brown sugar, and lemon juice. This combination ensures that the fruit retains its juicy consistency while baking, infusing the muffins with a delightful sweetness and tang. Set this mixture aside to allow the flavors to meld.

Step 4: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and grated zest. This step is crucial as it combines your leavening agents and flavors, ensuring an even distribution throughout the batter, leading to a perfectly risen muffin.

Step 5: Combine Wet Ingredients
Create a well in the center of your dry ingredient mixture and add the beaten egg, canola oil, melted butter, buttermilk, and vanilla extract. Gently stir the ingredients together until just combined, being careful not to overmix. This will keep your muffins tender and fluffy, the hallmark of the Big Buttermilk Strawberry Rhubarb Muffins.

Step 6: Fill the Muffin Tin
Divide the muffin batter evenly among the 6 prepared cups, filling them about two-thirds full. Spoon the strawberry and rhubarb mixture over the batter, followed by a generous sprinkle of the streusel topping. This layered approach ensures each bite of your muffins bursts with flavor and texture.

Step 7: Bake to Perfection
Place the filled muffin tin in the preheated oven and bake for 22–27 minutes. Keep an eye on them until they turn golden brown and a toothpick inserted into the center comes out with a few moist crumbs. The aroma of baked strawberries and rhubarb will fill your kitchen, signaling that these delightful treats are almost ready!

Big Buttermilk Strawberry Rhubarb Muffins Recipe FAQs

What should I look for when selecting strawberries and rhubarb for this recipe?
Absolutely! When choosing strawberries, look for ones that are bright red, plump, and fragrant, avoiding any with dark spots or mushy areas. As for rhubarb, select firm stalks with vibrant color; those that are smooth and crisp will have the best flavor.

How can I store my muffins to keep them fresh?
For optimal freshness, store your Big Buttermilk Strawberry Rhubarb Muffins in an airtight container at room temperature for up to 3 days. If you want to keep them longer, freezing them is a fantastic option!

What are the proper instructions for freezing the muffins?
I often make a batch to freeze for future enjoyment! To freeze, wrap each muffin individually in plastic wrap, ensuring they are tightly sealed. Place them in a freezer-safe bag or container, and they can be stored for up to 2 months.

What should I do if my muffins didn’t rise properly?
Very! Ensure both your baking powder and baking soda are fresh.
