How To Get Perfect Jumbo Muffins

To get perfect high-domed muffins like you would in a bakery at home, there is a specific process to get the best results. 

While you can simply fill muffin cups halfway and pop in the oven until done, to get the super puffy, airy, and light jumbo muffins you love from your favorite bakery, you’ll want to follow these important tips for how to get high domed muffins at home: 

  • -Bake Jumbo Muffins 5-10 minutes more than you would regular muffins. 
  • -Use a spatula or a spoon to mix muffins, not a mixer. 
  • -Refrigerate dough, covered, for at least one hour after mixing, up to overnight. 
  • -Preheat the oven to 425 degrees. 
  • -Bake muffins for about 6-8 minutes (until they have risen just past the muffin cup top) at 425 degrees. 
  • -Reduce heat to 350 for the second half of baking. 
  • -Always let muffins cool on a rack instead of in the pan, as leaving muffins in the pan will make the bottoms soggy as the steam we used to build a high domed muffin gets trapped and makes the texture soggy!

How To Freeze Muffins

These muffins are great for meal prep since they can be frozen easily if you have too many, or if you’d like to have them portioned out individually.

  • Tightly wrap each muffin in plastic wrap. 
  • Add plastic wrapped muffins to a large freezer sized ziploc bag and freeze for up to 6 months. 
  • When ready to eat, let muffin thaw naturally overnight in the refrigerator or in a cool, dry place. 
  • Pop in the oven or microwave to warm, and enjoy!

Easy Double Chocolate Chunk Muffins Recipe - delicious, fluffy and moist double chocolate chunk muffins are bursting with chocolate flavor - and tons of chunks of chocolate in every bite! 


  • 9 1/2 oz all purpose flour about 2 cups
  • 3 1/2 oz cocoa powder about 3/4 cup
  • 1 tbsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp sea salt
  • 1 1/2 cups sugar
  • 2 extra large eggs
  • 8 tbsp unsalted butter melted
  • 1 cup plain yogurt or buttermilk
  • 1 tbsp vanilla extract
  • 1 1/2 cups chocolate chunks or chocolate chips


  1. In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
  2. Toss the chocolate chunks into the dry ingredients to coat the chocolate chunks in flour (which will help them not sink to the bottom of the mix when baking!)
  3. Make a well in the middle and add in eggs and vanilla, whisking vigorously.
  4. Using a large spoon, mix rest of ingredients in to muffins until large clumps are gone and batter is consistently mixed - but do not overwork muffin batter.
  5. Cover batter and refrigerate for one hour to overnight.
  6. Preheat oven to 425 degrees.
  7. Fill muffin cups to 3/4 full.
  8. Bake at 425 for 6-10 minutes, until muffins have puffed slightly above muffin liner.
  9. Reduce heat to 350 (DONT open oven when you do this) and bake until sides of muffins are slightly crunchy and a toothpick inserted in the middle comes out clean (after about 25-30 minutes total baking time.)

  1. I’m wondering why mine turned out so bad. My batter was thick and hard, like a bad play dough. I measured everything exactly. The muffins didn’t rise and were very hard and ugly.

    1. Hmmm are you using buttermilk and is your butter melted and cooled. If you stick the butter from the microwave straight into the cold batter it can react badly with the batter… Please let me know if you do figure it out, Ill make a batch at home to check the measurements.

  2. These look exactly the same as the picture! I added 1 tablespoon of milk, as I couldn’t stir the batter toward the end of mixing. I also used sour cream instead of yogurt. I baked them 8 minutes at 425 then 18 minutes at 325. Recipe made 18 muffins which were in between regular and jumbo in size. I stirred these in a bowl although the mixer was calling to me and I will ALWAYS stir in a bowl and refrigerate overnight -this is what I think gives the great results.

    1. Just made those and they turned out delicious. I halved the siga r and used 180g of dark chocolate and they were perfect. Imagine would have been too sweet for us had i followed the original recipe to the letter..
      Didn’t chill them either as was pushed for time and they still worked a treat!

  3. These muffins turned out very tasty. I added 3 eggs because mine weren’t extra large. I also added a few tablespoons of water to the batter because it was too stiff. In addition I took out some of the sugar (1 cup) and substituted 1/2 cup of monksweet to make them healthier. These muffins are richer and choclatier than costco muffins. Also I didn’t refrigerate my batter and cooked them in ramekins and they still turned out great.

  4. Wonderful recipe! I made these with 5oz Greek yogurt plus 5oz whole milk because that is what I had on hand. The batter was VERY thick. They turned out fluffy, moist, and husband approved! Made 25 regular sized muffins, with suggested less 10 min cooking time.
