Ingredients You Need
- 1 box yellow cake mix, 15.25 ounces (Betty Crocker, Pillsbury, or Duncan Hines all work)
- 1/2 cup unsalted butter, melted and slightly cooled (or use 1/2 cup neutral oil for extra soft bars)
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 2 to 3 tablespoons milk, as needed for spreadable dough
- 1 cup chocolate chips (semi-sweet, milk, or a mix)
- 1/2 cup candies such as mini M&M’s, chopped peanut butter cups, or butterscotch chips
- 1/4 teaspoon fine salt if your cake mix tastes very sweet
- Optional finish: 1/2 teaspoon flaky sea salt
Pantry shortcuts and notes:
- Use nonstick spray or parchment with overhang for easy lift.
- Swap yellow cake mix for white, chocolate, funfetti, or spice without changing the method.
- Stir in up to 1.5 cups total mix-ins. Keep the dough thick, not runny.
Equipment:
- 9 by 13 inch metal baking pan
- Large mixing bowl and sturdy spatula
- Measuring cups and spoons
- Parchment paper or nonstick foil
- Cooling rack and sharp knife
Quick Tips & substitutions
- Melt butter but do not add it hot, or the chocolate chips may melt in the bowl.
- If the dough looks dry or crumbly, add milk 1 tablespoon at a time until it spreads like thick brownie batter.
- Prefer oil over butter for a softer, more cake-like crumb; stick with butter for richer flavor.
- Use a metal pan for even browning; glass pans can run a few minutes longer.
- Do not overbake. Pull the pan when the edges look set and the center still looks slightly glossy.
- Swap chocolate chips for white chocolate, butterscotch, or chopped nuts. Keep mix-ins under 1.5 cups total.
- Add 1 teaspoon espresso powder with the dry mix to deepen chocolate flavor in a chocolate base.
- Stir in 1/2 cup sprinkles with a white or funfetti mix for a party vibe.
- Gluten-free cake mix works well; check box size and add milk as needed to reach spreadable consistency.
How to Make Cake Mix Cookie Bars Recipe
Prep the pan and oven
- Heat the oven to 350°F. Line a 9 by 13 inch metal pan with parchment and lightly coat it.
Mix the wet ingredients
- In a large bowl, whisk the melted butter, eggs, and vanilla until smooth.
Add the cake mix
- Pour in the dry cake mix and salt. Stir with a spatula until a thick dough forms. Add milk 1 tablespoon at a time until the dough spreads easily.
Fold in the mix-ins
- Gently fold in chocolate chips and candies. Spread the dough into the pan in an even layer, nudging it into the corners.
Bake
- Bake 20 to 24 minutes, until the edges look golden and the center no longer jiggles. A toothpick near the center should show a few moist crumbs, not wet batter.
Cool and slice
- Set the pan on a rack and cool at least 20 minutes. Lift out by the parchment, slice into bars, and add flaky sea salt if you like sweet-salty contrast.
Variations
- Salted caramel: Drizzle 1/3 cup thick caramel over the spread batter, swirl lightly, then bake. Finish with flaky salt.
- Peanut butter cup: Use chocolate cake mix and fold in chopped peanut butter cups, then finish with a warm peanut butter drizzle.
- S’mores: Use yellow or chocolate mix, fold in mini marshmallows, chocolate chunks, and crushed graham crackers.
- Red velvet chip: Use red velvet mix with white chocolate chips and a light cream cheese glaze after cooling.
- Churro style: Use yellow mix, brush warm bars with melted butter, and dust with cinnamon sugar.
Ways to Serve
- Serve warm with a scoop of vanilla ice cream.
- Pack chilled bars in lunchboxes or picnics.
- Crumble over yogurt or pudding for a quick dessert parfait.
- Pair with coffee or hot chocolate for an easy afternoon treat.
- Top with a thin swipe of chocolate frosting for a bakery-look platter.
Storage
Let bars cool fully before storing. Keep them in an airtight container at room temperature for 3 days or in the fridge for 6 days. Freeze tightly wrapped bars for up to 2 months, then thaw at room temperature. Warm a slice in the microwave for 8 to 10 seconds if you want melty chips again.
