Ingredients

  • 1 box yellow cake mix
  • 1/2 cup brown sugar
  • 1/2 cup oil
  • 2 tablespoons water
  • 2 eggs
  • 1 small package chocolate chip bits
  • 1/2 cup chopped nuts

Instructions

  1. Mix yellow cake mix, brown sugar, oil, water, and eggs together until well combined.
  2. Pour the batter into a 9 x 13-inch ungreased baking pan.
  3. Sprinkle chocolate chips and chopped nuts evenly over the batter.
  4. Bake at 325°F for 25 minutes.
  5. Remove from oven and cut with a knife to create a marbled pattern.
  6. Continue baking for an additional 20 to 25 minutes.
  7. Allow the dessert to cool completely, then cut into bars and serve.

Tips & Substitutions

For a richer flavor, consider adding a teaspoon of vanilla extract to the batter. If you prefer a nut-free version, simply omit the chopped nuts or replace them with more chocolate chips. You can also substitute the yellow cake mix with a gluten-free cake mix for a gluten-free option. If you're in a hurry, use a pre-made frosting for topping.

Serving Suggestions

These marbled cookie squares are delicious on their own but can be served with a scoop of vanilla ice cream or a drizzle of chocolate sauce for a decadent dessert. They pair beautifully with a cup of coffee or tea. For a fun twist, try serving them with a side of whipped cream or alongside slices of Tammy Wynette Sour Cream Pound Cake.

Storage & Reheating

Store leftover marbled cookie squares in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate for up to a week. To reheat, place a square in the microwave for about 10-15 seconds or until warm. They can also be enjoyed cold straight from the fridge.

Frequently Asked Questions

Can I use a different cake mix flavor?

Absolutely! You can experiment with different flavors of cake mix, such as chocolate or lemon, to create your own unique version of marbled cookie squares. Just keep in mind that the flavor of the mix will influence the overall taste, so choose one that complements the chocolate chips.

What can I substitute for eggs in this recipe?

If you're looking to make this recipe egg-free, you can substitute each egg with 1/4 cup of unsweetened applesauce or a mashed ripe banana. This will keep the texture moist while still allowing the squares to rise during baking.

How can I make these squares more chocolatey?

To enhance the chocolate flavor, consider adding a few tablespoons of cocoa powder to the batter or increasing the amount of chocolate chip bits. For an even richer experience, you can swirl in some melted chocolate before baking to create a decadent marbled effect.
