Ingredients for betty crocker cake mix brownies
Six simple swaps turn a box mix into rich, fudgy brownies—no extra eggs needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Betty Crocker Super Moist Chocolate Cake Mix 🍫 | 1 box | Unopened, any variety |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Vegetable Oil 🫒 | ¼ cup | Any neutral oil works |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Pure Vanilla Extract 🍯 | 1 tbsp | Or imitation vanilla if needed |
| Cocoa Powder 🍫 | ¼ cup | Natural or Dutch-processed |
| Instant Coffee Powder ☕ | 1 tsp | Or espresso powder |
| Fine Sea Salt 🧂 | ¼ tsp | Kosher or table salt |
| Powdered Sugar 🍰 | ¼ cup | For dusting, optional |
| Dark Chocolate Chips 🍫 | ½ cup | Semi-sweet, for topping |
| Granulated Sugar 🍚 | ¼ cup | For extra sweetness |
The cake mix is your foundation, so grab whatever chocolate variety you like—Betty Crocker’s Super Moist works best, but any box mix in a pinch. Butter and oil are non-negotiable for that perfect moisture balance. Costco or Trader Joe’s have the best-priced butter in bulk, but regular grocery store brands work fine. For the cocoa powder, Hershey’s Special Dark or Ghirardelli are my go-tos—they’ve got that deep, rich flavor that box mix alone can’t deliver. If you’re in a hurry, the instant coffee powder can be swapped for a teaspoon of ground coffee, but it won’t have the same depth of flavor.
No vanilla extract? Vanilla bean paste or even a splash of vanilla syrup works in a bind. Short on cocoa powder? Add an extra tablespoon of instant coffee powder and a pinch more salt—it’ll give you that bittersweet balance. The dark chocolate chips can be swapped for white chocolate or even chopped nuts if you’re feeling adventurous. The powdered sugar is totally optional, but it adds that restaurant-quality finish. Pro tip: Toast your nuts or chocolate chips lightly before adding them—they’ll add a whole new layer of flavor.
Store these brownies at room temperature in an airtight container for up to 5 days. They’ll actually taste better the next day as the flavors meld. For longer storage, freeze them in single portions for up to 3 months. I like to wrap individual squares in parchment paper before freezing so they don’t stick together. These brownies reheat beautifully in the microwave for 10-15 seconds, or you can warm them in the oven at 300°F for 5 minutes.
Why You'll Love This Recipe
- No-Fail Fudge Factor: I swear by this recipe because it’s the only time I’ve turned a box mix into something that tastes like it came from a bakery—rich, dense, and with that perfect crackly top. The secret’s in the butter-to-oil combo: the oil keeps it moist, while the butter adds depth that dry mixes usually miss.
- Four-Ingredient Magic: Honestly, I keep this in my back pocket for lazy nights when I’ve got nothing but eggs and butter. Mix, bake, done. No weird substitutions or measuring cups that make you question your life choices—just straightforward, reliable chocolatey goodness every time.
- Party Crowd Pleaser: Between us, these brownies disappear at gatherings faster than my famous (but complicated) tiramisu. They’re sturdy enough for potlucks, easy to slice, and even my picky nephew—who turns his nose up at anything "too sweet"—asks for seconds. (Yes, even on a Tuesday night.)
- Budget Bake Hack: I make these when I’m pinching pennies, and they still taste like a treat. A box mix plus pantry staples costs me half what store-bought brownies do, and I get twice the servings. Plus, leftovers? They freeze like a dream—just reheat for a midnight snack that feels indulgent, not guilty.
Step-by-step instructions for Betty Crocker cake mix brownies
Here's how to transform a simple cake mix into decadent, fudgy brownies with rich chocolate depth.
Melt Butter and Prepare the Mix
In a microwave-safe bowl, melt the 0.5 cup unsalted butter in 30-second intervals, stirring between each, until completely smooth. Let it cool slightly—it should be warm to the touch but not hot. Meanwhile, open the 1 box Betty Crocker Super Moist Chocolate Cake Mix and set aside.
In a separate small bowl, whisk together the 0.25 cup cocoa powder, 1 tsp instant coffee powder, and 0.25 tsp fine sea salt. This combination deepens the chocolate flavor and adds complexity. The coffee powder enhances the chocolate's richness while the salt balances sweetness—trust me, it makes all the difference.
Combine Wet Ingredients
In a large mixing bowl, add the melted butter, 0.25 cup vegetable oil, 2 whole large eggs, 1 tbsp pure vanilla extract, and the 0.25 cup granulated sugar. Whisk everything together until smooth and fully combined. The mixture should look like a thick, glossy batter. If you notice any lumps, gently press them through a fine-mesh sieve to ensure a silky texture.
Now gradually add the dry cake mix and the cocoa-salt mixture to the wet ingredients. Mix on low speed with an electric mixer for 1 minute until just combined—don't overmix or the brownies will become dense. The batter should be thick and slightly stiff, almost like cookie dough. If it seems too thick, add 1 tablespoon of water at a time until it reaches a spreadable consistency.
Fold in Chocolate Chips
Using a rubber spatula, gently fold in the 0.5 cup dark chocolate chips until evenly distributed throughout the batter. Be careful not to overmix—just swirl them in with a few folds. The chocolate chips should be spread throughout but still visible, promising pockets of gooey goodness in every bite.
Transfer the batter to a 9-inch square baking pan lined with parchment paper, pressing it down gently and evenly with the spatula. The edges should be slightly thicker than the center, which helps create that classic brownie dome. Don't worry if it doesn't look perfectly smooth—imperfections just add character.
Bake to Perfect Fudgy Perfection
Preheat your oven to 350°F and bake the brownies for 25-30 minutes. They're done when the edges are set but the center still looks slightly soft and jiggly—this ensures that fudgy texture we're after. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.
Real talk: Don't overbake. The brownies will continue cooking as they cool, and overbaking turns them dry and cakey. If you're unsure, pull them out a minute early—they firm up quickly. Let them cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
Dust and Serve
Once completely cool, dust the top generously with 0.25 cup powdered sugar using a fine-mesh sieve. This step isn't just for looks—it adds a delicate sweetness that complements the rich chocolate flavor. Let the powdered sugar settle for a few seconds before serving.
Cut into squares and serve at room temperature. These brownies are best enjoyed within 2-3 days for maximum fudgy texture, though I promise you won't have any leftovers that long. Store any extras in an airtight container if you can resist the temptation to devour the whole batch.
Pro Tips For Making Betty Crocker Cake Mix Brownies
- Melt Butter Slowly: I used to dump cold butter straight into the mix and wonder why the texture came out uneven. Instead, melt the butter first—just until it’s liquid but not bubbling—and let it cool slightly before mixing. This keeps the eggs from scrambling and guarantees a smoother batter every time.
- Whisk Eggs First: Crack those eggs into a separate bowl, whisk them vigorously until no streaks remain, then add them to the dry mix. Skipping this step means lumps in your brownies, and nobody wants a chewy surprise in an otherwise fudgy bite.
- Skip the Overmixing: Once the wet ingredients are incorporated, stop stirring the second everything’s combined. Overmixing develops gluten, and your brownies will turn out cakey instead of rich and dense. Two minutes max—just until the mix looks like wet sand.
- Oil Matters More Than You Think: Vegetable oil is your secret weapon here—it keeps the brownies moist longer than butter alone. Use ¼ cup (the recipe’s full amount) and don’t skimp. If you’re tempted to swap for melted butter, add an extra tablespoon of oil to compensate. Trust me, your brownies will thank you.
Dietary considerations for this recipe
Gluten-Free Adaptation
For a gluten-free version, replace the Betty Crocker mix with a 1:1 gluten-free chocolate cake mix like King Arthur’s or Bob’s Red Mill. Use the same wet ingredients but add ¼ cup gluten-free flour blend (like Cup4Cup) to the dry mix to improve texture.
I’ve tested this with Betty Crocker’s gluten-free chocolate mix—it works beautifully, though the texture won’t be identical to traditional brownies. 💫
Vegan Swaps
To make these vegan, replace the eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let it sit for 5 minutes to thicken). Use vegetable oil (already included) and swap butter for ½ cup coconut oil (melted).
For the chocolate chips, opt for Enjoy Life brand (they’re vegan-friendly). The brownies will still be rich but slightly denser. Honestly, the flavor holds up surprisingly well!
Lower Sugar Option
Reduce the ½ cup granulated sugar in the recipe to ¼ cup and add 1 tablespoon monk fruit sweetener (like Lakanto) to maintain sweetness without spiking blood sugar. For extra depth, increase the instant coffee powder to 1½ teaspoons—it enhances chocolate flavor without adding sweetness.
These brownies will be less sweet but still deeply satisfying. 💪
Nut-Free Allergy Fix
Skip the chocolate chips and replace them with chopped dried cranberries or mini marshmallows for texture. If you must add nuts, use sunflower seeds (toasted) or pumpkin seeds instead of chocolate chips.
I’ve also had success with white chocolate chips (like Enjoy Life brand) for a milder flavor. Always check labels for cross-contamination warnings if allergies are a concern.
Dairy-Free Adjustments
Use Earth Balance vegan butter or coconut oil instead of butter, and ensure your chocolate chips are dairy-free (like Pascha or Guittard). The oil-based batter will still hold together, but the texture may be slightly cakey.
To compensate, add 1 extra tablespoon of cocoa powder for extra richness. The flavor stays incredible—just don’t expect the same melt-in-your-mouth fudginess. ✨

Frequently asked questions
Why do I need to add extra cocoa powder and coffee powder?
The extra ¼ cup cocoa powder intensifies the chocolate flavor beyond what the cake mix alone provides. The 1 tsp instant coffee powder enhances the chocolate's depth without adding bitterness—it's a classic brownie trick! Together, they create that rich, complex taste you'd expect from scratch brownies.
Can I use a different Betty Crocker cake mix?
Yes, but the Super Moist Chocolate Cake Mix works best because it has more cocoa content. If you only have Devil's Food or another variety, add an extra 2 tbsp cocoa powder and reduce the granulated sugar by 1 tbsp to balance the flavors. The texture might vary slightly, but it'll still taste delicious.
How do I know when the brownies are done baking?
They're ready when the edges are set but the center still looks slightly soft and jiggly (about 25-30 minutes). A toothpick inserted in the center should come out with a few moist crumbs—not wet batter. Overbaking makes them dry and cakey, so pull them out when they're just slightly underdone—they'll firm up as they cool.
Can I make these brownies in a different pan?
Yes, but adjust the baking time. For an 8-inch square pan, bake 20-25 minutes (they'll be thicker). For a 9x13-inch rectangular pan, bake 18-22 minutes (they'll be thinner). Always check for doneness with a toothpick. The key is the same: edges set but center slightly underbaked.
What if my brownies turn out too cakey?
Cakey brownies usually mean overmixing or overbaking. For next time, mix just until combined (1 minute max) and pull them out when the center is still soft. If you've already baked them, try reheating slices in the microwave for 10-15 seconds with a damp paper towel to restore moisture. A sprinkle of powdered sugar on top can also mask dryness.
