That’s such a sweet memory. ❤️ Many people call “Michigan Rocks” a type of old-fashioned chocolate cookie that’s slightly crisp outside, soft inside, and usually dusted with powdered sugar. They’re sometimes also known as chocolate crinkle–style cookies in parts of the Midwest.
Here’s a classic version that’s very close to what many families remember:
Michigan Rocks (Old-Fashioned Chocolate Cookies)
Ingredients
- 1 cup butter, softened
- 1 ¾ cups sugar
- 2 eggs
- 1 tsp vanilla extract
- 2 cups all-purpose flour
- ¾ cup cocoa powder
- 2 tsp baking powder
- ¼ tsp salt
- ½ cup powdered sugar (for coating)
Instructions
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Cream butter and sugar in a bowl until light and fluffy.
- Add eggs and vanilla, mixing well.
- In another bowl, combine flour, cocoa powder, baking powder, and salt.
- Gradually mix the dry ingredients into the wet mixture until a thick dough forms.
- Chill the dough for about 30 minutes (this helps shape the cookies).
- Roll dough into small balls (about 1 inch).
- Roll each ball in powdered sugar until well coated.
- Place on baking sheet and bake 10–12 minutes.
- Let cool slightly—the tops will crack and look “rocky,” which is how they got the name.
💡 Why they’re called “Michigan Rocks”:
When the cookies bake, the powdered sugar cracks over the dark chocolate dough, making them look like little snow-covered rocks, which is where the nickname came from in some Michigan families.
