First, gather all your ingredients and preheat the oven to 300 degrees Fahrenheit. This low baking temperature will help to achieve that perfect chewy texture we all love in Chocolate Crinkle Cookies.
In a mixing bowl, combine the flour, cocoa powder, baking soda, and salt. Whisk them together until well mixed; this helps to evenly distribute the leavening agent throughout the dry ingredients.
In another bowl, melt the butter and combine it with the sugar. Mix until the sugar is fully incorporated. The mixture should be smooth and glossy.
Add the egg and vanilla extract to the butter-sugar mixture, continuing to blend until everything is combined.
Next, slowly add the dry ingredients to the wet ingredients, stirring until a dough forms. Don’t overmix; you want just enough to combine everything.
Once the dough comes together, cover it and place it in the freezer for about 30 minutes. This step is crucial for developing that classic crinkle look!
After chilling, prepare your baking sheet with parchment paper for easy removal. Roll the dough into small balls, about an inch in diameter.
Now, it’s time to coat the dough balls! Roll them in powdered sugar until they are generously coated, ensuring they are fully covered.
Place the sugar-coated balls on the prepared baking sheet, leaving space between each cookie for expansion.
Bake the cookies in the preheated oven for around 12 minutes. They should look slightly underdone but firm around the edges.
Once baked, remove them from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. The cookies will firm up as they cool, giving you that perfect chewy texture.
Finally, store any leftovers in an airtight container for up to five days. Enjoy your delicious Chocolate Crinkle Cookies!
