I always start by making the almond cream because it sets the flavor base of the whole recipe. In a bowl, I mix butter, sugar, eggs, and almond flour until smooth and creamy. This mixture should feel thick but spreadable like soft frosting.
Next, I slice the giant croissant carefully without cutting it fully apart. Then I brush it generously with simple syrup so it soaks up moisture and sweetness. This step ensures every bite stays soft inside and crisp outside.
Now I spread a thick layer of almond cream inside the croissant. I also add some on top for that signature bakery-style look and texture. Finally, I sprinkle sliced almonds generously for crunch and flavor.
I place the croissant in a preheated oven and bake until golden brown. The almond filling should puff slightly and turn lightly crisp on top. Once baked, I let it cool slightly before dusting with powdered sugar.
