Why These Cookies are a Must-Try
Lazy Cake Cookies are more than just a quick fix — they deliver serious dessert satisfaction with almost no effort.

Add chocolate chips, peanut butter cups, chopped candy bars, or crushed pretzels for a sweet and salty twist.

Tools You’ll Need
You don’t need special equipment for Lazy Cake Cookies. Here’s what you’ll want on hand:
-
Mixing bowl
-
Spoon or spatula
-
9×13 baking dish
-
Parchment paper or nonstick spray

Measuring cups

Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper or lightly grease it to prevent sticking.
Step 2: Make the Dough
In a mixing bowl, combine the cake mix, melted butter, and eggs. Stir until a thick dough forms. It will be dense — that’s normal.
Step 3: Add Your Mix-Ins
Fold in chocolate chips, M&Ms, or your favorite candy pieces. Don’t overmix.
Step 4: Spread the Dough
Press the dough evenly into the prepared pan. Use clean hands or a spatula to flatten it to the edges.
Step 5: Bake
Bake for 20–25 minutes, or until the edges are golden brown and the center is just set. Do not overbake if you want gooey centers.
Step 6: Cool and Cut
Let the bars cool in the pan for at least 20 minutes. Lift out using the parchment paper and slice into squares or rectangles.

-
Even thickness. Press dough evenly for consistent baking.

Cool fully before slicing. Hot bars may crumble if cut too early.
