Ingredients for black bean chocolate cake mix
These 14 ingredients create a decadent vegan cake with rich chocolate depth and subtle coffee notes.
| Ingredient | Amount | Notes |
|---|---|---|
| Black Beans 🌱 | 1 ½ cups | Canned, drained and rinsed |
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | High-quality Dutch-processed |
| Granulated Sugar 🍚 | 1 ½ cups | Organic preferred |
| Coconut Oil 🥥 | ¾ cup | Melted, full-fat preferred |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar |
| Coffee Extract ☕ | 1 tbsp | Pure, not instant |
| Ground Flaxseed 🌾 | 3 tbsp | Freshly ground for flax eggs |
| Almond Milk 🥛 | ¾ cup | Unsweetened, room temperature |
| Baking Soda 🧂 | 1 tsp | Pure, not baking powder |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Espresso Powder ☕ | 1 tbsp | Finely ground for depth |
| Dark Chocolate Chips 🍫 | 1 cup | Vegan, 70% cocoa |
| Walnuts 🌰 | ½ cup | Chopped, lightly toasted |
The black beans are the secret weapon here—cannellini or pinto beans work best for their mild flavor and creamy texture. Grab the organic canned variety from Trader Joe's or Whole Foods for the best quality, or cook your own for maximum freshness. The cocoa powder is non-negotiable; Valrhona or Guittard brands deliver that professional depth. For the coffee extract, Starbucks or McCormick are reliable, but avoid anything with artificial flavors. The espresso powder adds an extra layer of complexity—Lavazza or Illy are excellent choices if you want to splurge.
No flaxseed? Chia seeds work at double the amount—simply mix 6 tbsp chia seeds with 0.75 cup water. Running low on almond milk? Oat or soy milk are perfect substitutes, though the texture may vary slightly. The coconut oil must be melted—microwave 40 seconds to just soften it, then stir until fully liquid. For the chocolate chips, Enjoy Life brand is the gold standard for vegan baking, but any dairy-free chips will work. The walnuts can be omitted if you prefer a nut-free version, but they add wonderful crunch and richness to the crumb.
Store the dry ingredients—flour, cocoa, sugar—in airtight containers for up to 6 months in a cool, dark place. The flaxseed should be kept in the fridge once opened to prevent rancidity. The cake itself keeps well for 4-5 days at room temperature or 1 week refrigerated. For longer storage, slice and freeze portions for up to 3 months. The coffee and chocolate flavors actually intensify after a day or two, making leftovers even more delicious.

Step-by-step instructions for black bean chocolate cake mix
Here's how to create a rich, fudgy chocolate cake with deep coffee notes and perfect moisture.
Prepare the Flax Eggs and Mix Dry Ingredients
In a small bowl, whisk together the 3 tablespoons ground flaxseed with the 0.75 cup almond milk. Let this mixture sit for 5 minutes until it thickens into a gel-like consistency—this creates your egg substitute. Meanwhile, in a separate large bowl, sift together the 2 cups all-purpose flour, 0.75 cup unsweetened cocoa powder, 1 tablespoon espresso powder, 1 teaspoon baking soda, and 0.5 teaspoon salt. Whisk thoroughly to eliminate any lumps and ensure even distribution of the cocoa powder.
This step is critical for achieving that signature dense yet moist texture. The espresso powder enhances the chocolate flavor without adding bitterness, while the baking soda ensures proper rise. Don't skip the sifting—it prevents a grainy texture in the final cake.
Combine Wet Ingredients for a Smooth Batter
In a separate bowl, melt the 0.75 cup coconut oil over low heat or in the microwave until completely liquid. Add the melted oil to the dry ingredients along with the 1.5 cups granulated sugar, 1 tablespoon vanilla extract, 1 tablespoon coffee extract, and the thickened flax egg mixture. Using an electric mixer on medium speed, beat for 2-3 minutes until the batter is completely smooth and all ingredients are fully incorporated.
Here's the thing—this batter should be thick but pourable. If it looks too stiff, add 1-2 tablespoons almond milk to loosen it. The coffee extract and cocoa powder work together to create that signature deep chocolate flavor with subtle bitterness that pairs perfectly with the walnuts and chocolate chips.
Fold in Chocolate and Walnuts
Gently fold in the 1 cup dark chocolate chips and 0.5 cup chopped walnuts using a spatula, being careful not to overmix. The chocolate chips will melt slightly from the warm batter, creating pockets of molten chocolate throughout the cake. Divide the batter evenly between two 8-inch round cake pans lined with parchment paper or lightly greased with coconut oil.
Real talk: Don't press down on the batter when pouring—this can create dense layers. Instead, use a spatula to spread it evenly. The walnuts add a satisfying crunch that contrasts beautifully with the fudgy texture, while the chocolate chips ensure each bite has that classic chocolate cake experience.
Bake to Perfect Doneness
Preheat your oven to 350°F. Bake the cakes for 30-35 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter). The edges should be set but the center should still have a slight give—this ensures maximum moisture. Rotate the pans halfway through baking for even heat distribution.
This is where patience pays off. Overbaking dries out the cake, while underbaking leaves it too dense. The black beans work their magic here, adding moisture that keeps the cake tender even after cooling. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Pro Tips For Making Black Bean Chocolate Cake Mix
- BLEND BEANS SMOOTH: I learned this the hard way—skipping the food processor and just mashing beans with a fork leaves gritty bits that ruin the texture. Pulse them in batches until they’re silky, like hummus, not chunky like refried beans. (Yes, even if you’re impatient like me.)
- WHISK COCOA FIRST: Dissolve the unsweetened cocoa powder in the coconut oil before adding liquids—this prevents clumps that turn into dry patches in your cake. Stir vigorously for 30 seconds until it’s the color of melted chocolate, not speckled.
- DON’T OVERMIX THE BATTER: Once you fold in the flour and sugar, stop after 10 strokes. Black bean batter is dense, and overmixing makes it tough. Just combine until just combined—lumps are fine, texture is what matters.
- BAKE UNTIL TOOTHPICK TESTS CLEAN: This cake’s dense, so the toothpick might look moist but still be done. Wait until it comes out with one crumb and no wet batter clinging. If it’s sticky, bake 5 more minutes—underbaking is the real trap here.
Essential equipment for this dish
Must-Have Mixing Tools
An electric mixer (like a KitchenAid stand mixer or Cuisinart hand mixer) is my go-to for blending the batter smoothly. The flat beater attachment handles the thick black bean batter better than whisk attachments.
If you don’t have one, a hand mixer works fine—just mix on medium-high speed for 2-3 minutes to fully incorporate all ingredients. 💫
Baking Essentials
Two 8-inch round cake pans are essential—Wilton Perfect Results pans with non-stick coating work perfectly. Line them with parchment paper or lightly grease with coconut oil to prevent sticking.
For even baking, I recommend Oven Thermometer like Thermoworks to ensure your oven hits 350°F accurately—many home ovens run hot or cold. ⚡
Measuring Precisely
Use stainless steel measuring cups (like OXO Good Grips) for dry ingredients and a liquid measuring cup for the almond milk and melted coconut oil. The black beans should be measured packed—press them down slightly in the cup to get the exact 1.5 cups.
A digital kitchen scale (like Escali Primo) is ideal for the cocoa powder and sugar to avoid packing errors. 🔥
Optional Extras
A fine-mesh sieve (like Microplane) helps sift the flour and cocoa powder for a silky texture. For the walnuts, a food processor (like Ninja Mini) makes quick work of chopping them evenly.
If you love chocolate ganache, a double boiler (or heatproof bowl over a pot of simmering water) is perfect for melting the dark chocolate chips smoothly. ✨
Storage Solutions
An airtight container (like Rubbermaid Brilliance) keeps the cake fresh for 4-5 days at room temperature. For longer storage, quart-sized freezer bags work best—squeeze out excess air before sealing.
A sharp serrated knife (like Victorinox) makes clean slices, especially after freezing. Label your containers with dates to track freshness! 📅
Nutrition facts
Frequently asked questions
Why do black beans make this cake moist?
Black beans add natural moisture and protein that mimics the binding properties of eggs. Their creamy texture creates a tender crumb while reducing the need for extra fat. The beans also contribute to the cake's rich, dense structure that stays fresh for days without drying out.
Can I make this cake in a single layer instead of two?
Yes! Use a 9-inch round pan and reduce baking time to 25-30 minutes. For even cooking, place the pan on the middle rack and rotate halfway. The single layer will be thicker but equally moist—just monitor closely to avoid overbaking.
What if I don't have coffee extract?
No problem! Use 1 tablespoon instant espresso powder dissolved in 1 tablespoon hot water instead. For a milder flavor, skip it entirely—the chocolate will still taste rich, just without the coffee depth. The extract enhances flavor but isn't essential for success.
How can I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add 1 teaspoon xanthan gum to improve texture. The cake may be slightly denser but will still be moist and delicious. For best results, use a gluten-free measuring method to avoid packing errors.
Why does my cake taste bitter?
Excessive cocoa powder or espresso powder can create bitterness. The recipe balances this with sugar and vanilla. If it's too strong, try reducing the cocoa to 0.5 cup and adding 1 extra tablespoon sugar. Also ensure you're using high-quality cocoa—cheap brands often have bitter aftertastes.
