These are made using a classic thumbprint cookie dough, which is stuffed with a creamy chocolate frosting, and topped with mini eggs. There's no doubt that Christmas Mini Egg Thumbprint Cookies will be the first cookie to disappear from your cookie platter!
Preheat oven to 350°F. Prepare a baking sheet by lining it with parchment paper or a silicone baking mat. Set aside.
In a mixing bowl, use a hand-held mixer to beat together the butter and sugar until well combined.
Add the egg and vanilla extract. Beat into the butter and sugar mixture.
Add the flour and baking powder. Beat until just combined. Do not overmix.
In one tablespoon portions, roll the dough into balls and place on prepared baking sheet at least 2 inches apart.
Bake for 10 minutes.
Remove from oven and use a teaspoon measuring spoon to push a dent/thumbprint into the top of each cookie. Allow cookies to cool for 3 minutes. Transfer to a wire cooling rack to finish cooling.
For the Chocolate Frosting:
Melt the butter and pour into a mixing bowl. Add the remaining frosting ingredients to the bowl and whisk until well combined.
If the frosting is too thick, thin it out with a teaspoon of hot water at a time.
Transfer frosting to a Ziploc bag. Cut about a 1/4 inch from the bottom of one corner. Use the bag to squeeze the frosting into the thumbprint of each cooled cookie.
Top with mini eggs, pushing them gently into the frosting to ensure they stick.
Allow cookies to sit for two hours for the frosting to set. Enjoy!
