These Jumbo Double Chocolate Muffins are inspired by the viral Olympic Village Chocolate Muffins. They are rich, moist, and chocolatey with a ganache filled center, and come together with just 15 minutes of fuss-free work!
Read the full blog post below for detailed notes, tips, tricks, photos and videos.
What Are The Olympic Chocolate Muffins?
The chocolate muffins sold at the Olympic Village in Paris rose to fame in August 2024 after Norwegian swimmer, Henrik Christiansen, made a series of viral TikTok videos sharing his unabashed obsession with them. In his videos, he was seen hoarding these muffins and entering a “love affair” with them. Following his craze, many other Olympians and locals visited the Olympic Village to try these muffins and share their reviews. The consensus? They really were that great. Everyone who tried them commented on how rich, moist and gooey they were – unlike typical muffins which tend to be dry.
The Olympic Chocolate Muffins are jumbo sized double chocolate muffins with dark and milk chocolate chunks, and what appears to be a filling of dark chocolate ganache in the middle. And that is exactly what I have achieved with this recipe!
Best Muffin Tin For This Recipe
These are “jumbo” muffins, so you need a jumbo muffin pan for this recipe, like this one from Amazon or this one from Target. If you are not able to get a jumbo muffin pan, you can use a regular sized muffin pan and make more muffins; just be sure to adjust baking time accordingly.
How To Line Muffin Pans With Parchment Paper
You can make your own muffin liners with parchment paper. To do this,
- Cut parchment paper into large squares which can cover the muffin cup and rise above it (about 6-7″ squared)
- Fold each square into a triangle by aligning two opposite corners, then fold again into a smaller triangle. When unfolded, the square should have a cross in it with two lines connecting the 4 corners and meeting in the middle to form a point
- Make cuts along the lines, starting from the corner and coming slightly more than halfway to the middle. This should leave an area in the middle of the square that is roughly the same size as the bottom of the muffin cup
- Place the square on a muffin cup, and use a glass to press it down. The cuts and folding will allow the parchment paper to fold up naturally and perfectly line the cup!
Best Chocolate For This Recipe
These Jumbo Double Chocolate Muffins have square chunks of chocolate in them instead of chocolate chips. That doesn’t mean chips don’t work, but I recommend chunks to get an exact replica! You can find dark chocolate chunks at Whole Foods or Target. I did have a harder time finding milk chocolate chunks, so ended up getting Lindt milk chocolate and cutting it into squares myself (which you can also do for the dark chocolate).

Ingredients
Muffins:
- 2 cups all purpose flour (260g)
- ¾ cup granulated sugar (150g)
- ¾ cup light brown sugar (150g)
- 2 tsp baking powder
- 1 tsp baking soda
- 1 tsp salt
- 2 large eggs
- 2/3 cup vegetable oil (130g)
- 1 cup sour cream (240g) — can sub buttermilk; see FAQs
- 1/2 cup Dutch Processed cocoa powder (50g)
- 2 tsp instant coffee
- 1/2 cup boiling water (120g)
- 1/2 cup dark chocolate chunks (100g) + more for top
- 1/2 cup milk chocolate chunks (100g) + more for top
Ganache:
- 1/2 cup dark or semi-sweet chocolate chunks (100g)
- 1/3 cup heavy cream (80g)
Instructions
- Pre-heat oven to 375F (conventional / no fan) and line a jumbo muffin tray with parchment paper or muffin liners. The parchment liners should rise slightly above the surface of the tray to allow the muffins to have height
- Sift the flour, granulated sugar, brown sugar, baking powder, baking soda and salt into a large bowl. Whisk to combine and ensure there are no lumps
- To the same bowl, add the eggs, oil and sour cream. Whisk gently until just combined and no lumps remain; do not overmix
- In a separate bowl, mix the cocoa powder, instant coffee and boiling water until a smooth, shiny mixture forms
- Add the cocoa powder mixture to the remaining batter, and gently fold until combined. Do not overmix
- Add the dark and milk chocolate chunks to the batter and fold it in
- Divide the batter evenly between 6 jumbo muffin cups. The cups should be filled almost to the brim but not all the way. The liners will help ensure the batter does not flow over, but if you are worried, save ~1/2 cup of the batter and pour it into a ramekin to bake instead
- Top the muffins with more chocolate chunks
- Bake at 375F for ~27-30 minutes, until a toothpick inserted into the muffins comes out with light crumbs (no wet batter). Let the muffins cool down for 20 minutes
- While the muffins are baking, make the ganache. Heat the cream until it just starts to boil, and pour over the chocolate in a bowl. Cover and wait 5 minutes, then stir until a smooth ganache forms. Let the ganache cool down at room temperature, it should thicken up
- Once the muffins have cooled down (they should still be slightly warm but not hot), transfer the ganache into a piping bag with a round tip. Carefully lift each muffin, puncture in the middle with the piping tip, and fill generously with ganache. Some ganache will ooze out of the top, which is what we want
- Serve and enjoy! These muffins are best eaten warm when the ganache and chocolate chunks are not firm.

Can this make 12 regular sized muffins? How long would they need to cook for?
Zoha Malik
Yes, you can! Regular sized muffins (assuming you’re using a cupcake tin) bake in around 15-18 minutes usually
Ayezel
I loved these!
Safana Hussain
Alhamdulillah, these muffins turned out absolutely amazing! So soft, fluffy, and moist. I even replaced the regular flour with whole wheat flour, and honestly there was barely any difference in texture — they still came out light and delicious. The recipe was easy to follow and gave such great results. Definitely making these again in shaa Allah!
Zoha Malik
Wow, great to know the flour substitute works so well in this recipe! THank you for the kind review
Helda
Hello Zoha, is it possible to omit the cocoa powder to make just a chocolate ganache muffin? Do i need to add more flour though? Thank you
Zoha Malik
Hi Helda! no, this recipe is specifically developed with cocoa powder so removing it will impact the taste and texture.

Made these as mini cupcakes with my 7 year old daughter and here is her review “Mumma, I loved Zoha aunty’s recipe. These are the best cupcakes ever! Can I have these for breakfast, lunch and dinner?” I reduced the quantity of sugar a little and used half cup sour cream and half cup yogurt. So so easy to make and super delicious 🤤
