This homemade almond-filled croissant turns your leftover pastries into a French delicacy that's better than what you'd grab in a Parisian cafe. Soaking the croissants in rum-flavored syrup brings them back to life, while the smooth almond cream gives them that genuine bakeshop taste that makes everyone ask for seconds.
I learned this trick during a cooking class in Lyon and have made it countless times for my family's weekend breakfasts. The amazing smell of almonds and butter floating through the house gets everyone to the table faster than any buzzing alarm ever could.
What You'll Need
- Croissants from yesterday: Let them sit out overnight to get slightly stale so they'll soak up all the tasty syrup
- Rum: Gives that real French bakery smell and flavor, though you can swap in vanilla if you don't want alcohol
- Almond meal: Forms the heart of the filling with its rich nutty taste
- Unsalted butter: Lets you manage the saltiness while adding that must-have richness
- Eggs: Hold the filling together and create that lovely pudding-like middle when baked
- Sliced almonds: Add a pretty look and nice crunch against the soft filling
- Powdered sugar: The final touch that gives that bakery look and cuts through the richness
How To Make Them
- Mix Up The Syrup:
- Stir water, sugar, and rum in a small pot. Heat gently until sugar melts completely then let cool. This simple mix will breathe new life into old croissants and add that hint of rum flavor.
- Whip Up The Almond Cream:
- Beat sugar, almond meal, and salt in your stand mixer with the whisk. Add butter and mix until fully combined. Drop in eggs one by one, beating on medium-high until it gets fluffy like frosting. You want it light and spreadable, not too runny.
- Get The Croissants Ready:
- Cut each croissant in half like you would for a sandwich. Quickly dip both halves in the cooled syrup so all sides get damp but not soggy. Put them on a baking sheet lined with parchment, cut sides up.
- Put Them Together:
- Scoop about two tablespoons of almond cream onto the bottom half of each croissant. Place the top piece over the filling then spread another spoonful on top. Be generous but don't let it spill over the sides.
- Add The Toppings:
- Scatter sliced almonds all over the top of each croissant so they stick to the cream. They'll get toasty while baking and look pretty while adding a nice crunch.
- Bake Until Golden:
- Cook at 350°F for 15-18 minutes until the almond cream turns golden and sets up nicely. They should be crispy outside but still soft inside. Let them cool a bit before dusting with powdered sugar.
My grandma always poured in extra rum beyond what the recipe said, calling it her "hidden trick." When I started making these myself, I realized she was spot on about that extra splash making the flavor so much deeper.
Prep Them Early
You can get these croissants ready the night before baking. Just put everything together, cover with plastic wrap, and stick them in the fridge. In the morning, let them sit out for about 20 minutes before baking. It's perfect for holiday mornings when you want something fancy without waking up super early.
What To Serve With Them
These almond-filled treats go great with strong coffee or espresso to balance the sweetness. The bitter coffee notes really bring out the almond flavor. If you're hosting a bigger brunch, add some fresh berries and a spoonful of crème fraîche on the side for a tangy contrast to the richness.
Where They Came From
Almond croissants started as a clever way for French bakers to use up leftover pastries. Instead of throwing away unsold croissants, they came up with this smart way to transform them into something new and amazing. What began as a practical fix for food waste has turned into one of the most popular treats in French bakeries everywhere.
Frequently Asked Questions
- → What kind of croissants work best?
Pick croissants that are a day old and have sat uncovered overnight. This lets them soak up syrup without falling apart.

- → Why use syrup on croissants?
The syrup keeps croissants moist and infuses them with gentle sweetness, making them richer.
- → Is rum a must-have ingredient?
Rum enhances flavor but isn’t crucial. Skip it or swap for vanilla extract for a softer taste.
- → What’s the best way to store them?
Although freshest right away, store them in a sealed container for up to two days. Reheat for a better texture when serving.
- → Can I prep the almond filling early?
