Ingredients

• Baking staples: Eggs and neutral oil (vegetable, canola, or light olive oil).
• Pecans: Chopped pecans add texture and flavor. Swap for walnuts or almonds, or omit entirely if you prefer nut-free cookies.
• Icing: Butter, milk (dairy or plant-based), powdered sugar, and unsweetened cocoa powder. Use half-and-half or cream for an extra-rich icing if desired.

Instructions

1. Make the cookie dough:
   In a large bowl, combine the cake mix, eggs, and oil. Stir until a thick dough forms. Fold in the chopped pecans and set aside.
2. Shape and bake:
   Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or lightly spray them. Form 1-inch dough balls with a cookie scoop or your hands, spacing them a couple of inches apart. Bake for 8–10 minutes, or until the bottoms are set and slightly crisp while the centers remain soft.
3. Prepare the chocolate icing:
   In a small saucepan over medium heat, melt 1/2 cup butter. Whisk in 3 tablespoons milk and 2 tablespoons unsweetened cocoa powder; simmer briefly until the mixture slightly thickens (about 3–5 minutes). Remove from heat and whisk in 2 cups powdered sugar until smooth. The icing will thicken as it cools. Adjust milk quantity for desired consistency.
4. Finish:
   Transfer baked cookies to a cooling rack. When they have cooled for 5–10 minutes, spoon or drizzle the chocolate icing over each cookie. Allow the icing to set for a few minutes before serving.

Storage:
Store finished cookies at room temperature in a covered container for up to one week. If possible, keep them in a single layer so the icing does not stick to other cookies.

Pro tips

Icing tip: Let the cookies cool for about 5–10 minutes before adding icing. This prevents the icing from melting and running off the sides. Place the cooling rack over a tray or sheet to catch any drips.

Baking tip: Avoid overbaking—these cookies should remain soft and slightly fluffy in the center. Remove them from the oven when the bottoms are set and the centers still feel slightly tender.

Fun fact: What is a Texas sheet cake?
