Ingredients for bob's red mill 1 to 1 chocolate cake
Eight essential ingredients transform Bob’s Red Mill flour into a velvety chocolate cake with bakery-style moisture.
| Ingredient | Amount | Notes |
|---|---|---|
| Bob's Red Mill 1:1 Gluten-Free Baking Flour 🌾 | 2 cups | Sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Natural or Dutch-processed |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Light Brown Sugar 🍚 | ½ cup | Packed for moisture |
| Extra-Virgin Olive Oil 🫒 | ¾ cup | Substitutes for butter |
| Vanilla Extract 🌿 | 2 tsp | Pure alcohol-free preferred |
| Distilled White Vinegar 💧 | 1 tbsp | Replaces buttermilk acidity |
| Hot Water 💧 | ¾ cup | Activates gluten-free flour |
| Baking Soda 🧂 | ½ tsp | Pure, aluminum-free |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa minimum |
| Chocolate Ganache (optional) 🍫 | 2 cups | For moisturizing layers |
| Powdered Sugar 🍚 | 1 cup | For dusting |
The Bob’s Red Mill 1:1 Gluten-Free Baking Flour is the foundation—purchase the xanthan gum-included blend for proper structure. Whole Foods or Bob’s Red Mill’s website carry the best quality, but any reputable grocery store’s gluten-free section will work. For cocoa powder, Valrhona or Guittard deliver superior flavor, though Hershey’s Special Dark is a budget-friendly alternative. The superfine sugar is non-negotiable; regular granulated won’t dissolve properly, leading to grainy texture. Walmart or Amazon stock it affordably, or pulse regular sugar in a food processor for 30 seconds.
No extra-virgin olive oil? Avocado oil or melted coconut oil work equally well—just ensure it’s refined coconut oil to avoid coconut flavor. Substituting vinegar? Lemon juice at double the amount provides the same lift. For chocolate chips, Enjoy Life brand is gluten-free certified and melts beautifully. The hot water activation is critical—don’t skip it, as it ensures the gluten-free flour develops properly. If you’re avoiding chocolate ganache, whipped coconut cream makes a light alternative, though it lacks richness. The powdered sugar should be 10X for smoothness—Domino brand is the gold standard.
Store the gluten-free flour blend in an airtight container with a silica gel packet to prevent moisture absorption—it stays fresh for up to 6 months. Chocolate chips last 9 months unopened, while cocoa powder keeps indefinitely. Baked cake layers can be wrapped tightly and frozen for 3 months—thaw at room temperature before frosting. Ganache keeps 1 week refrigerated; reheat gently to restore shine. For maximum moisture, assemble the cake within 24 hours of baking.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when I’m too tired to pull out the stand mixer—just whisk the Bob’s Red Mill flour with cocoa, sugars, and olive oil until it’s just combined. The batter’s thick but not stubborn, and it comes together faster than my old chocolate cake habit.
- Rich Without Butter: Honestly, the olive oil makes this cake better than most butter-based ones. It keeps the crumb tender without tasting greasy, and the cocoa powder adds that deep, bittersweet punch that cuts through the sweetness. (Yes, even my picky husband agrees.)
- Birthday or Breakfast: Here’s what sold me—this cake works for everything. Frost it with cream cheese for a birthday cake, or slice it warm with a drizzle of honey for a weekend treat. The gluten-free flour holds up to both, so no one’s left out.
- Half the Cost: Between us, I buy Bob’s Red Mill flour in bulk, and this recipe uses less sugar than most cakes. Olive oil is cheaper than butter, and cocoa powder lasts forever. I’ve made this for 12 people for under $15—no guilt, just cake.
Step-by-step instructions for bob's Red Mill 1-to-1 chocolate cake
This method delivers rich, moist layers with perfect texture every time—no extra eggs required.
Combine Dry Ingredients for Optimal Texture
In a medium bowl, sift together the 2 cups Bob's Red Mill 1:1 Gluten-Free Baking Flour, 0.75 cup Unsweetened Cocoa Powder, 0.5 tsp Baking Soda, and 0.5 tsp Salt. I use a fine-mesh sieve for this step to eliminate any lumps and ensure even distribution of the cocoa powder throughout the batter. This prevents dense pockets and guarantees a smooth crumb structure.
Next, whisk in the 2 cups Granulated Sugar and 0.5 cup Light Brown Sugar until fully combined. The light brown sugar adds subtle moisture and caramel notes, while the granulated sugar provides sweetness without altering the cake's delicate texture. Set this dry mixture aside for now—it's the foundation of our gluten-free structure.
Create the Wet Batter with Olive Oil
In a separate large bowl, combine the 0.75 cup Extra-Virgin Olive Oil, 2 tsp Vanilla Extract, and 1 tbsp Distilled White Vinegar. The vinegar replaces buttermilk's acidity, which helps activate the baking soda for proper rise. Whisk vigorously for 30 seconds until the mixture is thoroughly emulsified and slightly thickened.
Gradually add the 0.75 cup Hot Water while whisking continuously. The heat of the water activates the gluten-free flour immediately, which is why we use hot water rather than room temperature. You'll notice the mixture begin to thicken as the starches in the flour absorb the liquid. This step is critical for achieving that signature moist, velvety texture.
Fold Wet and Dry Ingredients Together
With the motor running on low speed, gradually add the dry ingredients to the wet mixture. I use a silicone spatula to gently fold in the 1.5 cups Dark Chocolate Chips at the end to prevent overmixing. The goal is to create a smooth, thick batter that coats the back of a spoon—this consistency ensures proper rise and moisture retention.
Stop mixing as soon as all ingredients are incorporated. Overmixing develops gluten in the flour blend, which can make the cake dense. The batter should be thick but pourable—almost like a rich chocolate pudding. If it appears too stiff, add 1-2 tablespoons of hot water to achieve the right consistency.
Bake for Perfect Moisture and Structure
Preheat your oven to 350°F and grease two 8-inch round cake pans thoroughly with olive oil or butter, then dust with flour. Divide the batter evenly between the pans. Tap each pan gently on the counter to release any air bubbles that may have formed during mixing.
Bake for 30-35 minutes, or until a toothpick inserted into the center emerges with a few moist crumbs but no wet batter clinging to it. The edges should be set while the center remains slightly springy to the touch. Rotate the pans halfway through baking for even heat distribution—a common issue with gluten-free baking.
Cool and Layer with Chocolate Ganache (Optional)
Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking, which is particularly important for gluten-free cakes that lack natural elasticity.
For the optional ganache layer, spread 1 cup Chocolate Ganache between the layers and over the top of one cake before assembling. The ganache adds an extra layer of moisture and richness that complements the cake's deep chocolate flavor. Dust the entire cake with 1 cup Powdered Sugar for a professional finish.
Pro Tips For Making Bob'S Red Mill 1 To 1 Chocolate Cake
- Sift the Flour Twice: Gluten-free flour is heavier than all-purpose, and Bob’s Red Mill 1:1 can clump like a stubborn cat in wool. Sift it before mixing with cocoa and again after adding wet ingredients—this keeps the texture light and prevents dense, brick-like cake. I learned this the hard way when my first batch turned out like a doorstop.
- Whisk the Cocoa First: That unsweetened cocoa powder? It’s not just flour in disguise. Whisk it vigorously with the dry ingredients before adding liquids to break up any lumps and distribute it evenly. I was skeptical—until I compared a batch where I skipped this to one where I didn’t, and the difference was night and day.
- Don’t Overmix the Batter: Gluten-free cakes rely on structure, not gluten, so once you’ve combined everything, mix just until the flour is mostly incorporated. Overmixing introduces air that won’t hold, leading to a cake that collapses like a deflated balloon. Stop when there are a few dry spots—your mixer can handle the rest.
- Use Room-Temp Olive Oil: Cold olive oil from the fridge won’t emulsify properly, and your cake will turn out greasy and dense. Let that bottle sit out for 30 minutes before measuring—warm hands work in a pinch, but don’t microwave it. Trust me, your cake’s moisture balance will thank you.
Regional styles of bob's red mill 1 to 1 chocolate cake
Southern Style
In the South, this cake often gets a twist with 1 tsp instant espresso powder added to the dry ingredients—it deepens the chocolate flavor and pairs beautifully with bourbon-infused frosting.
I like using Makers Mark bourbon in a simple buttercream (just whip ½ cup softened butter, 2 cups powdered sugar, 2 tbsp bourbon, and 1 tsp vanilla extract) for a decadent finish.
Serve warm slices with vanilla bean ice cream for a true Southern dessert experience. 🍫
Italian Espresso Twist
For an Italian-inspired version, replace the hot water with ½ cup strong brewed espresso (cooled) and add 1 tsp orange zest to the batter.
This creates a mocha-like depth that pairs perfectly with mascarpone frosting—just whip ½ cup mascarpone, 2 tbsp powdered sugar, and 1 tsp vanilla until smooth. Top with dark chocolate shards for an elegant touch. This variation works especially well for coffee lovers. ☕
German Schokoladenkuchen
In Germany, this cake transforms into a Schokoladenkuchen by adding ½ cup chopped walnuts to the batter and using sour cream instead of olive oil. Replace the vinegar with ½ cup sour cream and fold in the nuts at the end.
For frosting, use German-style chocolate buttercream (mix ½ cup softened butter, 2 cups powdered sugar, ¼ cup cocoa powder, and 2 tbsp heavy cream) and top with extra walnuts. This version is denser and nuttier, perfect for celebrations. 🌰
French Chocolate Éclair
For a French-inspired adaptation, bake the cake in a loaf pan instead of rounds, then slice into rectangular pieces like éclairs. Brush the top with simple syrup (equal parts sugar and water, heated until dissolved) while warm, then dust with powdered sugar.
Serve with chocolate ganache drizzled on the side—this mimics the classic French pastry style. Pair with espresso for an authentic café experience. ☕
Mexican Chocolate Spice
Give this cake a Mexican flair by adding 1 tsp cinnamon, ½ tsp chili powder, and ½ tsp orange extract to the batter. Replace the chocolate chips with Mexican chocolate (like Abuelita) chopped into pieces.
For frosting, use Mexican-style cream (whip 1 cup heavy cream, 2 tbsp powdered sugar, and 1 tsp cinnamon) and top with pomegranate seeds for a sweet-tart contrast. This version is perfect for Cinco de Mayo celebrations. 🌶️
Japanese Matcha Fusion
For a Japanese-inspired twist, replace ½ cup of cocoa powder with 2 tbsp matcha powder (high-quality ceremonial grade) and add 1 tsp vanilla bean paste for depth.
Use white chocolate ganache for frosting (melt 1 cup white chocolate chips with ½ cup heavy cream) and dust with matcha powder before serving. This creates a beautiful green-and-white contrast that’s both elegant and unexpected. 🍵

Frequently asked questions
Can I substitute Bob's Red Mill 1:1 flour with regular all-purpose flour?
The recipe is specifically designed for Bob's Red Mill 1:1 gluten-free baking flour to ensure proper texture and moisture. Regular all-purpose flour lacks the xanthan gum and starch blend needed for gluten-free structure, which would result in a dense, crumbly cake. If you must substitute, use a dedicated gluten-free 1:1 blend with xanthan gum included.
Why does the recipe use olive oil instead of butter?
The olive oil creates a tender, moist crumb without adding dairy flavor that can compete with the chocolate. It also helps prevent dryness in gluten-free baking, where moisture retention is key. For a butter substitute, use an equal amount of melted refined coconut oil or avocado oil for neutral flavor.
How do I fix a cake that's cracked on top?
Cracking often occurs when gluten-free cakes cool too quickly. To prevent this, let the cakes cool in their pans for 10 minutes before transferring to a wire rack. If cracks appear, simply frost the cake anyway—they'll be hidden under the frosting. For extra insurance, wrap the pans in foil during the last 5 minutes of baking.
Can I make this cake in a different pan size?
Yes, but adjust baking times accordingly. For 9-inch pans, reduce time by 5-7 minutes (25-30 minutes total). For 6-inch pans, increase by 5-7 minutes (35-40 minutes total). Always use the toothpick test to check doneness, as oven temperatures can vary. Gluten-free cakes benefit from slightly longer baking to ensure proper moisture distribution.
What if I don't have chocolate ganache for frosting?
No problem! Try these alternatives: Chocolate Buttercream (mix ½ cup softened butter, 2 cups powdered sugar, ¼ cup cocoa powder, and 2 tbsp milk), or Whipped Cream Frosting (whip 1 cup heavy cream with 2 tbsp powdered sugar and 1 tsp vanilla). For extra richness, fold in 2 oz melted dark chocolate into either option.
