Ingredients Overview
The beauty of this recipe lies in its simplicity and clever use of ingredients. Store-bought croissants are ideal because they soak up the syrup better than freshly baked ones. The almond frangipane, made with almond flour, butter, sugar, and eggs, provides a luscious filling. A touch of rum in the simple syrup enhances the flavor, but vanilla extract works as a non-alcoholic alternative.
How to Make the Recipe
Step 1: Preheat the oven and prepare the baking sheet.
Set your oven to 350°F (175°C) and position a rack in the center. Line a baking sheet with parchment paper or a silicone mat to prevent sticking. This ensures the croissants bake evenly and clean-up is effortless.
Step 2: Make the simple syrup.
In a small saucepan, combine sugar, water, and rum (or vanilla extract). Heat over medium heat, swirling occasionally, until the sugar dissolves completely. Remove from heat and let it cool while preparing the frangipane.
Step 3: Mix the dry ingredients for the frangipane.
In a medium bowl, whisk together almond flour, all-purpose flour, and salt. Ensure there are no clumps, as a smooth mixture will create a better almond cream texture. Set this aside for the next step.
Step 4: Combine butter and sugar.
In a large bowl, use a spatula to blend softened butter with powdered sugar until smooth and creamy. This forms the base of the frangipane and should be free of lumps.
Step 5: Add egg and almond extract.
Mix the egg and almond extract into the butter mixture. The mixture may initially appear separated, but keep stirring until it becomes smooth and cohesive.
Step 6: Finish the frangipane.
Fold the dry ingredients into the butter mixture using a spatula. Stir until the frangipane is fully combined and has a creamy, spreadable consistency.
Step 7: Prepare the croissants.
Slice each croissant in half horizontally using a serrated knife. Brush the cut sides generously with the simple syrup or dip them briefly to ensure they soak up the flavor.
Step 8: Spread frangipane on the croissants.
Spread about 2 1/2 tablespoons of frangipane on the bottom half of each croissant. Replace the top halves, then spread 1 1/2 tablespoons of frangipane over each croissant’s top.
Step 9: Add sliced almonds.
Sprinkle sliced almonds generously over the tops of the croissants. Gently press them into the frangipane to ensure they stick and create a crisp, nutty topping when baked.
Step 10: Bake the croissants.
Place the assembled croissants on the prepared baking sheet and bake for 20 minutes. The tops should turn golden brown, and the almonds should be toasted. Let cool slightly and serve warm.

Tips for the Best Almond Croissants
- Use day-old or store-bought croissants for optimal texture.
- Let the simple syrup cool completely before using.
- For an extra almond kick, add a few drops of almond extract to the simple syrup.
Variations to Try
- Chocolate-Almond Croissants: Add a layer of chocolate chips inside the croissant before spreading the frangipane.
- Orange-Almond Croissants: Substitute the rum with orange liqueur or orange zest for a citrusy twist.
- Nut-Free Option: Replace almond flour with hazelnut or sunflower seed flour for a nut-free alternative.
Frequently Asked Questions
Q1: Can I make these ahead of time?
Yes! Prepare the simple syrup and frangipane in advance. Store them separately in the fridge for up to a week. Assemble the croissants just before baking.
Q2: Can I skip the rum in the recipe?
Absolutely! Use vanilla extract as a non-alcoholic substitute in the syrup.
Q3: What type of croissants work best?
Store-bought or slightly stale croissants are ideal as they soak up the syrup without becoming soggy.
Q4: Can I freeze almond croissants?
You can freeze assembled, unbaked croissants. Bake directly from frozen, adding a few extra minutes to the baking time.
Q5: How do I store leftovers?
For the best texture, serve almond croissants fresh. However, you can store baked croissants in an airtight container at room temperature for up to one day.

How to Store and Reheat
Storage: Store unbaked components (syrup and frangipane) in the refrigerator. Once baked, almond croissants are best enjoyed within a few hours.
Reheating: Warm baked croissants in a 300°F oven for 5-7 minutes to refresh their crispness.
