Transform store-bought butter croissant into stunning almond croissant worthy of a French pastry display case! Baking almond croissants at home is easier than you think. A Starbucks almond croissant runs a little over $3. It’s close to $5 at Proof Bakery in Atwater Village, Gjusta in Venice, and Republique in La Brea. Let’s make half a dozen almond croissants for a fraction of the price! Here’s what you need to make super easy almond croissants at home: store bought butter croissantsalmond simple syrupfrangipane (almond cream filling)sliced almondspowdered sugar (confections’ sugar) Equipment needed: hand mixer, stand mixer, or food processoroven or air fryer Costco Butter Croissants Any store-bought butter croissants will work. I highly recommend Costco’s butter croissants. In 2020, Costco changed their croissants. Their new recipe is better! It’s much higher in quality than the previous version. They are made with real butter, as opposed to other mass produced croissants made with oil (the much cheaper and less flavorful alternative). Plus, it’s hard to beat the great deal. $4.99 for a dozen butter croissants! Almond Croissant Filling There are several ways to make the almond cream filling. My version uses ground almonds (also labeled as almond flour). Use may skin on or blanched almonds. This recipe also works with sliced almonds. Just process the sliced almonds in a food processor. (More detailed instructions in the recipe card.) The ingredients are mixed together in a stand mixer, using an electric hand mixer, or a food processor. Simply, combine the ingredients together until creamy. What is frangipane? Frangipane is a creamy almond filling. It is used to fill various pastries, tarts, and other baked goods such as orange almond bostock. Frangipane is made by mixing together ground almonds with butter, sugar, and eggs. Since it contains raw eggs, the filling does need to be cooked before consuming. Frangipane can be made several days in advance. It keeps in the fridge up for a week. Filling & Assembling Croissants Use a serrated knife to slice croissant in half lengthwise. Brush insides of croissants with almond simple syrup. Lightly toast in the oven.Spread about 2 tablespoons of frangipane (almond cream) on bottom half of croissant.Replace top half of croissant.Spread about 1 tablespoon of frangipane over top of croissant.Press sliced almonds over frangipane topping.Drizzle remaining almond syrup all over assembled croissants. Bake until crisp and golden! Almond Syrup The almond syrup is a mixture of simple syrup, almond extract, and orange liqueur. Combine equal parts water and granulated sugar to make simple syrup. Orange liqueur is not required, but it does add a touch of extract flavor. I recommend Cointreau or Grand Marnier for best quality and flavor. The syrup adds a touch of sweetness. But more importantly, it helps to make the croissants crunchy without drying them out. Bake in a 350 degree F oven for until the sliced almonds are toasted and the croissant exterior is golden and crispy. The frangipane almond cream will also turn golden. Dust with sifted powdered sugar before serving! These are best enjoyed warm fresh from the oven while the croissants are crisp and crunchy. However, of course, they are also delicious at room temperature. Storage and Leftovers Remove from oven and let cool on baking sheet for about three minutes. Then, transfer to wire rack and dust with powdered sugar. Transferring to the wire rack will ensure the croissants remain crisp. Otherwise, they may steam and soften on the baking sheet. Cooled almond croissants can be left on wire rack all day. Keep in an airtight container for overnight storage. Reheat in a toaster oven or air fryer as directed below. Freezing Almond Croissants Freeze for longer storage! This method works with baked almond croissants. Cool to room temperature. Individually wrap each croissant tightly in plastic wrap. For extra protection, store wrapped croissants in an airtight freezer bag or reusable container. Keep in the freezer for up to one month. Defrosting and Reheating Leave wrapped frozen croissant at room temperature overnight. The following day, reheat thawed croissant in the oven, toaster oven, or air fryer. OVEN: 350 degree F oven for 8-10 minutes until heated throughout and crispy.TOASTER OVEN: Use roll reheat setting for 2 minutes, then use toast setting for 3 minutes.AIR FRYER: Use the bake setting at 350 degrees F for 5 minutes. I personally use this toaster oven and this air fryer. Using Traditional Oven vs Air Fryer I have tested this recipe using both a traditional oven and this specific air fryer. Oven is great for making a large batch of these almond croissants. While the air fryer is great for reheating. My air fryer is compact. As such, I am only able to make three almond croissants at a time. Where as I can easily fit two dozen almond croissants in my wall oven. The air fryer is wonderful for reheating day old or thawed croissants. The circulating dry heat revitalizes the old croissant back to it’s original crisp and crunchy glory.
