Directions

6. Moisten the edges of the smaller dough circle using a brush. Squeeze the almond cream in a spiral on the larger dough circle, seal the two layers of dough. Press firmly so no air is caught between the layers. Brush the icing on top. Slit the top of the cake with a knife, being careful not to pierce the dough. Refrigerate the galette for 30 minutes. Brush with icing a second time.
7. Bake for 35 minutes until it is golden brown. Let cool before serving.
