These hedgehog cookies are perfectly soft on the inside and coated in chocolate and crispy wafers on the outside. They're charming and almost too cute to eat!
Preheat the oven to 350°F. Line a large baking sheet with parchment paper and set aside.
In a large mixing bowl, beat the butter on medium speed for 2-3 minutes.
Meanwhile, press the cooked egg yolks through a fine mesh sieve to create a powder-like consistency.
Add the egg yolks and sour cream to the butter and mix until well combined.
In a separate bowl, combine the flour and baking powder. Add it gradually to the creamed butter, mixing until well incorporated.
Portion out the dough with a tablespoon or small cookie scoop. Roll each cookie into a ball and place on the baking sheet about half an inch apart.
Bake the cookies for 30-35 minutes. Allow them to cool completely on a wire rack.
In a small saucepan, combine all the ingredients for the chocolate glaze. Whisk over medium-low heat together until melted and smooth. Set the glaze aside to cool slightly.
In a food processor, pulse the wafers into crumbs.
Dip each cookie into the chocolate glaze to fully coat, then dredge in the crushed wafers. Repeat until all the cookies are coated. Let the glaze fully set, then enjoy!
