Ingredients for bob's red mill 1 to 1 chocolate cake
Bob's Red Mill flour and premium cocoa create a velvety chocolate cake with restaurant-quality texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Bob's Red Mill 1:1 Baking Flour 🌾 | 2 cups | Plus 2 tbsp for pan coating |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, cubed |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred for depth |
| Dutch-Processed Cocoa Powder 🍫 | ¾ cup | High-quality, unsweetened |
| Instant Espresso Powder ☕ | 1 tbsp | Enhances chocolate flavor |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Distilled White Vinegar 🍶 | 1 tbsp | Balances sweetness |
| Baking Soda 🧂 | ½ tsp | Pure, not baking powder |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Buttermilk 🥛 | ¾ cup | Homemade or store-bought |
| Hot Water 💧 | ½ cup | Freshly boiled |
The Bob's Red Mill 1:1 flour is non-negotiable here—its protein structure prevents cracking while maintaining moisture. Purchase directly from their website or specialty stores like Williams Sonoma for the best results. For the cocoa, Valrhona or Callebaut brands deliver superior flavor depth. The espresso powder can be found in the coffee aisle at Whole Foods or Starbucks stores. Room-temperature butter is crucial; let it sit out for 1 hour before measuring. If your butter is too cold, microwave it for 20 seconds to just soften—never melt it completely.
No Bob's Red Mill flour? King Arthur Measure for Measure is the closest substitute, but use it as a 1:1 replacement. Substituting regular all-purpose flour risks dryness—add 1 extra tbsp of buttermilk if you must. Dutch-process cocoa is essential for smooth texture; natural cocoa will make the cake denser. Out of espresso powder? Strong brewed coffee at half the amount works in a pinch. For the buttermilk, combine 0.75 cup milk with 1 tbsp vinegar if you're making it fresh. The hot water activates the baking soda for optimal rise—don't skip this step.
Store the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days if using a glaze. For longer storage, wrap tightly in plastic and freeze for up to 3 months. The cake improves overnight as the flavors meld. To maintain moisture, place a slice of bread on the cake's surface before storing. For serving, dust with powdered sugar or drizzle with warmed chocolate ganache—both elevate presentation without overpowering the rich chocolate flavor.

Step-by-step instructions for bob's Red Mill 1:1 chocolate cake
Master this technique and you'll achieve a perfectly fudgy chocolate cake with a moist crumb and no cracking.
👨🍳 Step 1: Prepare the Dry Ingredients and Mix Wet Components
In a medium bowl, whisk together the 2 cups Bob's Red Mill 1:1 Baking Flour, 0.5 tsp Baking Soda, and 0.5 tsp Diamond Crystal Kosher Salt. Sift this mixture into a separate large bowl to eliminate any lumps—this ensures an even texture throughout the cake. The 1:1 flour's protein structure needs this attention to prevent dense spots.
In another bowl, cream the 1.5 cups Unsalted Butter and 2 cups Granulated Sugar using an electric mixer on medium speed for 3-4 minutes until light and fluffy. The butter should be completely incorporated, leaving no grainy texture. This step is crucial for aerating the batter and creating that tender crumb. Scrape down the sides of the bowl as needed to maintain even mixing.
🍳 Step 2: Incorporate Eggs, Cocoa, and Flavor Enhancers
Add the 2 whole Large Eggs, one at a time, mixing well after each addition. Then stir in the 2 tsp Vanilla Extract and 1 tbsp Instant Espresso Powder. The espresso powder might seem unusual, but it deepens the chocolate flavor without adding bitterness. Mix until fully combined, then gradually add the dry ingredient mixture, alternating with the 0.75 cup Buttermilk, beginning and ending with the flour.
In a small bowl, whisk together the 1 tbsp Distilled White Vinegar and 0.5 cup Hot Water. This creates a simple buttermilk substitute that reacts with the baking soda to produce lift. The vinegar also helps balance the sweetness of the cake. Stir this mixture into the batter last, mixing just until combined. Overmixing at this stage can develop gluten and lead to a tougher cake.
🥘 Step 3: Prepare the Pan and Bake
Preheat your oven to 350°F. Generously grease two 8-inch round cake pans with butter and coat them with 2 tbsp of the Bob's Red Mill 1:1 Baking Flour, tapping out any excess. This prevents sticking and creates a clean release. Divide the batter evenly between the prepared pans, smoothing the tops with a spatula.
Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. The cake should be springy to the touch and pull away from the sides of the pan easily. I've found that the 1:1 flour often requires slightly longer baking than traditional cake flour, so don't rush this step. The cake is done when it reaches an internal temperature of 205-210°F.
⏰ Step 4: Cool and Check for Doneness
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking as the cake contracts. If you notice any cracks forming on the surface, don't panic—they're common with rich chocolate cakes but won't affect the texture.
For the fudgiest texture, I recommend wrapping the cooled cakes in plastic wrap and refrigerating for at least 1 hour before serving. This step intensifies the chocolate flavor and creates that signature moist, dense crumb. The cake will keep well in the refrigerator for up to 5 days, making it perfect for meal prep or special occasions.
Pro Tips For Making Bob'S Red Mill 1 To 1 Chocolate Cake
- Mix Dry Ingredients First: I learned this the hard way—whisking the cocoa powder into the butter before the flour leads to lumps that never fully dissolve. Sift or whisk the Bob’s Red Mill flour, cocoa, espresso powder, and salt together first, then cut in the butter. This ensures a smooth batter that bakes evenly, not a cake with weird pockets of dryness.
- Use Room-Temp Butter: Cold butter creates pockets of steam in the batter, which can cause your cake to sink or develop a dense crumb. Let the unsalted butter sit out for 30–60 minutes until it’s soft but not melted—press your finger into it, and it should leave a slight indent. This guarantees a tender, moist cake that doesn’t fight back with a tough texture.
- Don’t Overmix the Batter: The second you see streaks of flour disappearing, stop. Overmixing develops gluten in the Bob’s Red Mill 1:1 flour, turning your rich chocolate cake into a dense brick. Mix just until combined—about 20–30 seconds after the dry ingredients disappear. Your cake will thank you with a light, airy crumb instead of a sad, gummy one.
- Bake Until Springy, Not Dry: This cake’s done when the edges pull away from the pan and a toothpick comes out with moist crumbs, not wet batter. Overbaking dries out the chocolate flavor and makes the texture crumbly. If your oven runs hot, check at 28–30 minutes and tent with foil if needed—better to underbake slightly and let it rest than to kill the moisture.
Flavor customization for bob's red mill 1 to 1 chocolate cake
Spice Level Boost
For a subtle kick, add ½ tsp cayenne pepper or 1 tsp chili powder to the dry ingredients. This works surprisingly well with chocolate—think of it like a Mexican chocolate cake. I've tested this variation and found that ½ tsp cinnamon enhances the warmth without overpowering. 🌶️
Citrus Zest Twist
Brighten the flavor profile by adding 1 tbsp orange zest or 1 tsp lemon zest when mixing the wet ingredients. The acidity cuts through the richness beautifully.
For presentation, garnish with a few drops of orange syrup or candied orange peel. I like to use Valencia oranges for their sweet-tart balance.
Nutty Crunch Layer
Fold in ½ cup toasted walnuts or pecans during the final mixing stage for texture contrast. For extra richness, toast the nuts with 1 tbsp brown sugar and ½ tsp cinnamon before adding. This works especially well with the espresso-infused cake for a mocha-like flavor combination.
Boozy Elevation
Swap ¼ cup of the buttermilk for ¼ cup bourbon or dark rum to deepen the chocolate notes. The alcohol enhances the fudgy texture while adding complexity. For a lighter option, use 2 tbsp coffee liqueur instead of the espresso powder.
Let the cake sit overnight after baking to allow the alcohol flavors to meld fully.
Salted Caramel Swirl
Create a decadent version by preparing a simple caramel sauce with ½ cup brown sugar, ¼ cup heavy cream, and a pinch of flaky sea salt.
Pour it into the center of each cake layer before assembling, then swirl gently with a knife. This adds a luxurious touch that pairs perfectly with the chocolate's richness.
Seasonal Fruit Infusion
Add ½ cup mashed raspberries or blueberries to the batter for a fruity twist. The acidity balances the sweetness beautifully. For summer, try peaches or mango purée—just reduce the buttermilk by the same amount. I've found that frozen berries work just as well as fresh for convenience.
Nutrition facts
Frequently asked questions
Why does this recipe use Bob's Red Mill 1:1 flour instead of all-purpose?
The Bob's Red Mill 1:1 Baking Flour contains xanthan gum which mimics the protein structure of all-purpose flour, creating a tender crumb without requiring extra moisture. This prevents cracking while maintaining a fudgy texture—something regular flour can't do as effectively. The brand's blend also absorbs liquid differently, ensuring your cake stays moist for days.
Can I make this cake in a single 9-inch pan instead of two 8-inch pans?
Yes, but reduce the baking time by 5-7 minutes—the batter will spread more in a larger pan. Use a 9x2-inch pan and bake at 350°F for 28-32 minutes until a toothpick comes out clean. For even baking, rotate the pan halfway through. The texture will be slightly denser but still delicious.
What's the secret to avoiding cracks on the top?
Cracks happen when the cake cools too quickly. After baking, let it cool in the pan for 10 minutes before transferring to a wire rack. Also, avoid opening the oven door too early—temperature fluctuations cause surface tension. If cracks appear, they're purely cosmetic and won't affect taste. For extra insurance, brush the batter into the pan with a spatula to create an even surface.
How do I store leftovers without drying out the cake?
Wrap each layer tightly in plastic wrap, then place in an airtight container with a slice of bread on top to absorb moisture. Store at room temperature for 3 days or refrigerate for 5 days. For longer storage, freeze layers individually for up to 3 months. Thaw overnight in the fridge before serving. The bread trick keeps it moist longer than plastic alone.
Can I substitute Dutch-process cocoa with natural cocoa?
You can, but your cake will be denser and slightly bitter. Dutch-process cocoa is alkaline, which smooths out the flavor and creates a finer crumb. If using natural cocoa, reduce the baking soda to ¼ tsp and add ½ tsp baking powder to compensate for the lack of lift. The espresso powder helps balance any bitterness that remains.
