Ingredients for bob's red mill chocolate cake
Bob's Red Mill flour and cocoa powder create the signature moist crumb and deep espresso notes.
| Ingredient | Amount | Notes |
|---|---|---|
| Bob's Red Mill 1-to-1 Baking Flour 🌾 | 2 ½ cups | Lightweight for tender crumb |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Instant Espresso Powder ☕ | 2 tbsp | High-quality for bold flavor |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed |
| Sour Cream 🥛 | ½ cup | Full-fat for moisture |
| Buttermilk 🥛 | ½ cup | Freshly made |
| Hot Water 💧 | ½ cup | Just boiled |
| Chocolate Espresso Chips 🍫 | 1 cup | For texture contrast |
| Pistachios 🌰 | ¼ cup | Chopped, toasted |
The Bob's Red Mill 1-to-1 Baking Flour is non-negotiable here—it's specifically formulated to replicate the texture of all-purpose flour while adding subtle depth. Grab the 16-ounce bag from their website or your local health food store; it's worth the investment for this recipe. For the cocoa powder, Dutch-processed brands like Hershey's Special Dark or Valrhona are ideal—they're smoother and less bitter than natural cocoa. The espresso powder? Starbucks Via or Nescafé Azera work perfectly, but avoid instant coffee granules—they can make the cake grainy. Toast your pistachios in a dry pan for 3-4 minutes until fragrant; this enhances their nutty flavor and adds a delightful crunch to the crumb.
No Bob's Red Mill flour? King Arthur Measure for Measure is the closest substitute—just use the same amount. Running short on espresso powder? Dissolve 2 tbsp instant coffee granules in 1 tbsp hot water and use that instead. The chocolate espresso chips can be swapped for dark chocolate chunks, but they won't have that signature coffee kick. For the butter, European-style brands like Plugrá or President have higher fat content, which improves the cake's richness. If you're making this ahead, you can prepare the batter up to 24 hours in advance and refrigerate it—just let it sit at room temperature for 30 minutes before baking.
This cake tastes even better the next day as the flavors meld together. Wrap tightly in plastic wrap and store at room temperature for up to 3 days, or refrigerate for 5 days if you're using it for a crowd. For longer storage, slice and freeze individual portions for up to 3 months. The frosting options are endless, but I recommend a chocolate ganache made with heavy cream and chopped dark chocolate for that perfect balance of sweetness and acidity. Garnish with extra pistachios or chocolate shavings for a restaurant-worthy finish.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this recipe because it’s one bowl—no fussing with separate dry/wet mixes. Just toss the Bob’s Red Mill flour, cocoa, and sugars together, then fold in the wet stuff. Honestly, my 10-year-old could handle it (and has, multiple times).
- Deep Chocolate Magic: That instant espresso powder? It’s the secret weapon—intensifies the cocoa’s richness without tasting like coffee. The brown sugar keeps it moist, and the flour’s fine texture gives it a just-baked crumb. Between us, this is the kind of cake that makes store-bought look sad.
- Birthday to Brunch: Serve it warm with vanilla ice cream for a crowd-pleaser, or slice it cold for breakfast the next morning. I’ve even used leftover pieces in overnight oats—yes, really. (Yes, even on a Tuesday.)
- Budget-Friendly Luxury: Uses pantry staples you already own, plus the Bob’s Red Mill flour stretches further than all-purpose. Makes two 9-inch layers, so you’ll have leftovers for days—or freeze half for when you’re too lazy to bake. My wallet and taste buds thank me.
Step-by-step instructions for bob's Red Mill chocolate cake
This deep espresso-infused cake delivers fudgy layers with a satisfying crunch from espresso chips.
Cream Butter and Sugars for Maximum Moisture
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter on medium speed until completely smooth, about 2 minutes. This ensures no lumps remain for a velvety texture. Gradually add the 2 cups granulated sugar and 0.5 cup light brown sugar, mixing on medium-high speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume.
Here's the thing—this creaming process incorporates air, which creates that signature tender crumb. You'll know it's ready when the mixture leaves faint ribbons when the beaters are lifted. Scrape down the sides of the bowl with a spatula to ensure even mixing before proceeding.
Add Wet Ingredients and Espresso Powder
Reduce the mixer speed to low and add the 2 whole large eggs, one at a time, mixing just until each is fully incorporated after each addition. This prevents overmixing that could make the cake dense. Stir in the 2 tsp vanilla extract and 2 tbsp instant espresso powder until completely combined.
In a separate bowl, whisk together the 0.5 cup sour cream, 0.5 cup buttermilk, and 0.5 cup hot water. The hot water activates the baking soda for optimal rise. Gradually pour this mixture into the butter-sugar mixture, mixing on low speed just until combined—you should still see some flour streaks. Overmixing develops gluten, which leads to a tough cake.
Combine Dry Ingredients for Perfect Texture
In a medium bowl, sift together the 2.5 cups Bob's Red Mill 1-to-1 baking flour, 0.75 cup unsweetened cocoa powder, 1 tsp baking soda, and 0.5 tsp salt. This ensures even distribution of the leavening agents and prevents lumps. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined—again, stop as soon as you see no more flour streaks.
Fold in the 1 cup chocolate espresso chips and 0.25 cup chopped pistachios by hand using a silicone spatula. This gentle folding prevents deflating the batter while evenly distributing the crunchy elements. The batter should be thick but pourable—if it's too stiff, you may need to add 1-2 tablespoons of hot water to achieve the right consistency.
Bake in Two Layers for Even Cooking
Preheat your oven to 350°F and grease two 9-inch round cake pans with butter or baking spray, then line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops with a spatula. Bake for 30-35 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs.
I always tap the sides of the pans gently after 25 minutes—if the cake pulls away from the edges, it's ready. The top should be cracked but not fully set. Rotate the pans halfway through baking for even browning. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Layer and Frost for Ultimate Richness
Once completely cooled, level the tops of the cakes if needed. For a classic presentation, spread a thin layer of your favorite chocolate ganache or buttercream between the layers. Place the first layer on a cake stand or plate and add the second layer on top.
Frost the entire cake with another layer of ganache or buttercream, then decorate with additional chocolate espresso chips and pistachios for that signature crunch. The contrast of the fudgy cake layers, espresso crunch, and nutty pistachios makes every bite unforgettable. Serve at room temperature for the best texture and flavor experience.
Pro Tips For Making Bob'S Red Mill Chocolate Cake
- Sift the Cocoa First: I learned this the hard way—lumpy cocoa powder is the fast track to a cake that tastes like it’s fighting for its life. Sift the cocoa with the flour and espresso powder before mixing; it dissolves evenly and cuts down on the gritty texture that sneaks in when you’re in a hurry.
- Use Room-Temp Eggs: Cold eggs? That’s how you end up with a cake that’s dense enough to double as a doorstop. Let your eggs sit out for 30 minutes before cracking them—this ensures they blend smoothly with the wet ingredients and gives you that light, airy crumb you’re after.
- Don’t Overmix the Batter: I was skeptical until I tried it: mix just until the flour disappears. Overworking the batter introduces too much gluten, and suddenly your rich chocolate cake turns into a chewy brick. Stop when there are a few dry spots—your mixer’s done its job.
- Check Internal Temp: This isn’t the prettiest method, but it’s the tastiest: use an instant-read thermometer to pull the cake at 205–210°F. The edges might look set earlier, but the center needs that extra heat to fully develop flavor and avoid a gummy middle—trust the thermometer, not your eyes.

Low-Sugar Smart Swaps
For a lighter version, reduce the sugar by 2 tablespoons and replace with applesauce—this cuts calories while maintaining moisture. The brown sugar adds natural molasses for depth without extra sweetness. If watching carbs, use almond flour (replace ½ cup of Bob’s Red Mill flour) for a lower-glycemic option.
The espresso powder enhances chocolate flavor, so you can use less sugar without sacrificing richness.
Mood-Boosting Flavors
Chocolate triggers the release of serotonin, a neurotransmitter that improves mood and reduces stress. Pairing it with espresso’s caffeine creates a natural energy-mood combo. The vanilla adds aromatic compounds that promote relaxation, making this cake a perfect post-stress treat.
Studies show that enjoying dark chocolate can lower cortisol levels—perfect for unwinding after a long day. ✨

Frequently asked questions
Why does this cake use Bob's Red Mill flour instead of regular all-purpose flour?
The Bob's Red Mill 1-to-1 Baking Flour creates a lighter, more tender crumb while maintaining structure—perfect for rich chocolate cakes. It's specifically formulated to mimic all-purpose flour but with a finer texture that prevents dense, heavy layers. The subtle depth it adds also enhances the espresso notes in the recipe.
Can I make this cake in a single 9x13-inch pan instead of two layers?
Yes, but the texture will differ slightly. Reduce baking time to 25-30 minutes at 350°F and check for doneness with a toothpick. The cake will be denser without layers, but still delicious. For best results, use a springform pan and add an extra 0.25 cup of chocolate espresso chips on top before baking for extra crunch.
What's the best way to store leftover cake?
Wrap tightly in plastic wrap at room temperature for up to 3 days, or refrigerate for 5 days if using for large gatherings. For longer storage, slice and freeze individual portions for up to 3 months. The flavors actually improve overnight as the espresso and chocolate meld together!
Can I substitute the espresso powder with regular instant coffee?
Not recommended—espresso powder has a more concentrated flavor without the graininess of coffee granules. If you must substitute, dissolve 2 tbsp instant coffee in 1 tbsp hot water first to prevent lumps. For best results, use Starbucks Via or Nescafé Azera instant espresso powder. The espresso chips can't be replaced—they're essential for that signature crunch!
How do I fix a sunken center in my cake?
This usually happens from overbaking or opening the oven too soon. If it occurs, gently reheat the cake in a 300°F oven for 5-10 minutes to restore structure. For prevention, bake until a toothpick comes out with just a few moist crumbs (not completely clean). The two-layer method also helps distribute weight more evenly.
