Full steps and ingredients in recipe card below.
- Croissants: You want them to be stale - it's best to leave them out uncovered overnight or up to a few days. That way they get to soak up all the vanilla almond flavor in the syrup. I purchased my croissants from Costco.
- Almond flour: Or almond meal. You can also blend blanched almonds in a food processor - make sure you blend for a while to get the pieces really small. Or purchase almond flour online.
- Butter: Good quality, real unsalted butter will make all the difference!
- Sliced almonds: You can slice the almonds thinly by yourself or purchase pre-sliced almonds. Use leftover sliced almonds to make this easy strawberry almond crumble.
- Almond extract: This gives the filling that signature fragrant almond flavor. Without almond extract, it just won't taste like much! You can purchase almond extract online or in grocery stores next to vanilla extract.
👩🍳 How to make almond croissants:
First you make the syrup, then the filling. You assemble by dipping the croissants into the syrup, piping or spreading filling inside, topping with sliced almonds and baking!
Step 1: Combine water, sugar, vanilla, and almond extract in a medium saucepan and bring to a simmer. Stir to dissolve and let cool to room temperature while working on the filling.
Step 2: In a large bowl (or stand mixer or food processor), combine butter, sugar, eggs, salt, and almond extract. Have the butter very soft to make it easier to blend. Blend with an electric mixer or whisk vigorously with a wire whisk.
Step 3: Add almond flour and blend with a mixer or wooden spoon until creamy and mostly smooth. Transfer to a piping bag or a large disposable zippered bag with the end cut off. Skip the piping bag if you'll be filling with a spoon.
Step 4: Preheat oven to 375°F (190°C). Line a large baking tray with parchment paper.
Cut croissants in half (like for a sandwich). Dip both halves briefly in the syrup and lay out on a tray or baking sheet.
Step 5: Spread or pipe almond filling onto the bottom halves of the dipped croissants. Distribute evenly and make sure to leave about ¼ cup of filling in the bowl for topping the croissants.
Step 6: Place the top halves over the almond filled bottoms and spread a thin coating of filling on top of each croissant. Generously sprinkle with sliced almonds and press them in gently so they stick.
Step 7: Bake the croissants on a parchment lined baking sheet for 10-12 min, or until bottoms and tops are crisp and golden.
Step 8: Sprinkle baked croissants with powdered sugar and serve while warm or at room temperature.
Tip: Bake the croissants until they're crisp and golden on the outsides. But watch them so they don't burn!
🥄 Make ahead and storage
Store leftover filled and baked croissants in an airtight container refrigerated for up to 3 days. Reheat in the oven at 375°F (190°C) until buttery and crisp again.
You can prepare almond croissants ahead of time: assemble the croissants and just don't bake until they're ready! Refrigerate overnight in an airtight container, until ready to bake. They can last 24 hours unbaked.
❔ What is frangipane?
Frangipane is a mixture of butter, eggs, sugar, almond flour, and almond extract. Sometimes a small amount of flour is added to help it set and hold its shape better.
Frangipane is commonly used to fill lots of French and European pastries, pies, and tarts. That's because it's so easy to make and tastes like a buttery, rich almond custard when baked! So delicious.
📖 Recipe FAQs
I haven't tried filling croissants with marzipan but it definitely has a similar strong almond flavor. Frangipane does not typically contain marzipan.
I recommend using almond extract because it gives desserts that strong, floral almond flavor. I don't recommend leaving it out - it won't taste like an almond croissant. You can decide if you use natural or artificial almond extract - I prefer the flavor of natural almond extract.
I made 6 croissants using this recipe. You can also make 4 croissants and stuff them even more - using the same measurements. Halve the recipe for 3 croissants, and double for 12 croissants.
You can. Skip the syrup and bake as the recipe calls for. You may need to reduce the baking time by a few minutes because the croissants may crisp up faster.
You can use an electric mixer like I did. Or you could use a food processor, immersion blender, or even just a wooden spoon. Make sure all the ingredients are at room temperature for easy blending and have the butter extra soft.
