The Lazy Saturday Giant One-Bowl Blueberry Muffin Skillet
Listen, I absolutely love a good bakery blueberry muffin. But you know what I refuse to do on a Saturday morning? Meticulously line, fill, and later scrub a 12-cup muffin tin. Life is just too short for that kind of weekend labor. The inspiration for this giant skillet muffin hit me when I was staring down a pint of sad, wrinkled blueberries and a sink full of Friday night's dishes. I just wanted warm cake for breakfast without the fuss. Enter my favorite weekend hack: one giant, fluffy muffin baked right in a cast-iron skillet with a ridiculously crunchy, buttery streusel. You only need one mixing bowl, and the oven does all the heavy lifting while you drink your coffee. This recipe is incredibly special to me because it feels luxurious but takes practically zero effort, taking me back to slow childhood weekend mornings before the week's chaos begins. Want to make it your own? Swap the blueberries for raspberries or diced peaches, or toss in some chocolate chips. Yes, you can absolutely use frozen berries, just do not thaw them first or your batter will turn completely gray! Grab your skillet, pour some coffee, and let's get baking.

Ingredients
- 3/4 cup Unsalted butter(Divided; 1/2 cup for batter, 1/4 cup for streusel. Both melted.)
- 3/4 cup Granulated sugar
- 2 Large eggs(Room temperature if possible)
- 3/4 cup Sour cream or plain Greek yogurt(Full fat is highly recommended here for moisture)
- 1 tbsp Vanilla extract
- 2 1/2 cups All-purpose flour(Divided; 2 cups for batter, 1/2 cup for streusel)
- 2 tsp Baking powder
- 1/4 tsp Baking soda
- 1 tsp Kosher salt(Divided; 1/2 tsp for batter, 1/2 tsp for streusel)
- 1 1/2 cups Blueberries(Fresh or frozen. If frozen, do NOT thaw them first!)
- 1/3 cup Light brown sugar(Packed)
- 1/2 cup unsalted butter(melted, for the skillet in Step 1)
- 1/4 cup unsalted butter(melted, for the streusel in Step 4)
- 1/2 tsp kosher salt(for the streusel in Step 4)
Instructions
- 1
Preheat your oven to 375 degrees F. Place a 10-inch cast-iron skillet over medium-low heat and melt 1/2 cup unsalted butter. Once completely melted, pour the butter into your one large mixing bowl. Turn off the stove. Do not wipe the skillet out! That leftover slick of butter in the pan is going to give the edges of our giant muffin a deliciously crispy, almost fried texture.
5 min
Tip: If you don't have a cast-iron skillet, you can melt the butter in the microwave and bake this in a greased 9x9 baking dish, but cast-iron gives the best edges.

To the warm melted butter in your bowl, aggressively whisk in 3/4 cup granulated sugar, 2 large eggs, 3/4 cup sour cream, and 1 tbsp vanilla extract. Keep whisking until the mixture is completely smooth, glossy, and slightly pale.
3 min
Tip: Make sure your sour cream isn't freezing cold right out of the fridge, or it might cause the warm melted butter to clump up.
- 3
Switch from a whisk to a rubber spatula. Dump in 2 cups all-purpose flour, 2 tsp baking powder, 1/4 tsp baking soda, and 1/2 tsp kosher salt. Gently fold the dry ingredients into the wet until just barely combined—streaks of flour should still be visible. Add the 1 1/2 cups blueberries and fold two or three more times. Scrape the batter into your buttered skillet and smooth it out into an even layer.
2 min
Tip: Do not overmix! Overmixing develops the gluten and will give you a tough, rubbery cake instead of a tender muffin.
- 4
Listen to me: do not wash the bowl. Right into that exact same sticky bowl, toss in your streusel ingredients: 1/2 cup all-purpose flour, 1/3 cup light brown sugar, 1/4 cup unsalted butter (melted), and 1/2 tsp kosher salt. Use your fingers or a fork to mix and pinch everything together until it looks like wet sand with some big, glorious clumps. Scatter this streusel heavily and evenly over the batter in the skillet.
3 min
Tip: The leftover batter residue in the bowl actually acts as a binder and helps the streusel form those massive, bakery-style crumbs we all fight over.
- 5
Transfer the skillet to the middle rack of your oven. Bake for 35 to 40 minutes, or until the streusel is deeply golden brown and a toothpick inserted into the very center comes out clean (a few moist crumbs sticking to it is perfectly fine, just no wet batter).
35 min
Tip: If the streusel is browning too quickly around the 25-minute mark, tent the skillet loosely with foil for the remaining bake time.
- 6
Remove from the oven and let the giant muffin cool in the skillet for at least 15 minutes before serving. This resting time is mandatory—if you cut into it screaming hot, it will fall apart into a sloppy (though delicious) mess. Once rested, slice into wedges and serve.
15 min
Tip: Serve it right out of the skillet to save on dirty dishes. I highly recommend a smear of salted butter on a warm slice.
Chef's Notes
You can totally use frozen blueberries if that's what you have! Just promise me you won't thaw them first. If you thaw them, they'll bleed all over the batter and turn your beautiful Saturday morning breakfast a swampy, bruised gray color. Toss them in straight from the freezer. You might just need to add 2 to 3 extra minutes to your bake time.

Delicious doesn't have to be difficult
I spent a decade in restaurant kitchens before my daughter was born and I realized I needed a different relationship with food. The 16-hour days had to end, but my love of cooking didn't. Now I'm obsessed with the puzzle of making genuinely good food achievable on a Tuesday night. No weird ingredients, no 47-step processes—just smart techniques and bold flavors that come together fast. Because life is too short for boring weeknight dinners.
