Ingredients for bob's red mill 1 to 1 chocolate cake
Eight ingredients transform into velvety layers—no special skills needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Bob's Red Mill 1:1 Gluten-Free Baking Flour 🌾 | 2 cups | Mimics all-purpose texture perfectly |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat preferred |
| Granulated Sugar 🍚 | 1 ¾ cups | Superfine preferred for smooth batter |
| Dutch-Processed Cocoa Powder 🍫 | ¾ cup | High-quality for deep chocolate flavor |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Distilled White Vinegar 💧 | 1 tbsp | For tender crumb structure |
| Baking Soda 🧂 | ½ tsp | Freshly measured for lift |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Milk 🥛 | ½ cup | Room temperature, any variety |
| Vegetable Oil 🫒 | ¼ cup | Lightens texture without dryness |
| Dark Chocolate Chips 🍫 | 1 cup | 70% cocoa minimum for richness |
The Bob's Red Mill 1:1 flour is the game-changer here—grab the 32-ounce bag if you bake often, or buy just the 16-ounce bag for single batches. King Arthur is another great alternative if you can't find Bob's. The cocoa powder makes all the difference: Hershey's Special Dark or Valrhona for that restaurant-quality depth. Room-temperature butter is non-negotiable—cut it into cubes and let it sit for 2 hours if needed. The vinegar might sound odd, but it's what keeps this cake moist for days. I always double-check the expiration date on baking soda—it loses potency fast.
No Dutch-processed cocoa? Natural cocoa works in a pinch, but the flavor will be slightly more bitter. Out of vanilla extract? Almond extract at half the amount gives a similar warmth. The milk can be any kind—dairy, almond, or oat—but room temperature is key for proper emulsification. For extra richness, swap half the milk for heavy cream. The chocolate chips? Enjoy Life brand is my go-to for dietary flexibility, but any 70% cocoa or higher will do. Pro tip: toast the chocolate chips for 5 minutes at 350°F before adding—they'll melt perfectly into the batter.
This batter keeps covered in the fridge for up to 48 hours, making it perfect for meal prep. For best results, bake immediately after mixing, but you can prep the batter the night before. The cake stays moist for 5 days at room temperature if wrapped tightly in plastic. Freeze portions for up to 3 months—thaw overnight in the fridge before serving. I always bake two 9-inch rounds and freeze one for birthdays I can't predict. The texture improves overnight, so if you can wait, do it.

Step-by-step instructions for Bob's Red Mill 1:1 chocolate cake
This method delivers perfectly moist layers with minimal effort—no overmixing, no guesswork.
Cream Butter, Sugar, and Cocoa for Maximum Moisture
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter and 1.75 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. This step is crucial—you're incorporating air that will create that tender crumb. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing.
Reduce speed to low and gradually add the 0.75 cup Dutch-processed cocoa powder, mixing just until combined. The batter should be smooth with no visible streaks of cocoa. Here's the thing—Dutch-processed cocoa is already alkaline, so we're not adding any baking soda to it separately. This prevents any bitter aftertaste that can develop when combining acidic and alkaline ingredients.
Add Eggs, Vanilla, and Vinegar for Structure
Add the 2 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. The mixture will look slightly curdled at first, but don't worry—this will resolve when we add the dry ingredients. Next, stir in the 2 teaspoons vanilla extract and 1 tablespoon distilled white vinegar. The vinegar might seem unusual, but it reacts with the baking soda to create lift and tenderness in the crumb.
Increase the mixer speed to medium and beat for another 1 minute until the batter is completely smooth. This is where the magic happens—the vinegar and baking soda will create tiny air pockets that contribute to that signature light texture. If you're using room temperature eggs, they'll blend in more easily and create a smoother batter.
Combine Dry Ingredients and Fold in Chocolate Chips
In a separate bowl, whisk together the 2 cups Bob's Red Mill 1:1 gluten-free baking flour, 0.5 teaspoon baking soda, and 0.5 teaspoon salt. The gluten-free flour mimics all-purpose texture perfectly, so we don't need any special substitutions here. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined—you should still see a few streaks of flour. Overmixing develops gluten and can make the cake dense.
With the mixer still running on low speed, pour in the 0.5 cup milk and 0.25 cup vegetable oil. Mix just until the batter is smooth and homogeneous. Remove the bowl from the mixer and gently fold in the 1 cup dark chocolate chips using a silicone spatula. Make sure they're evenly distributed throughout the batter. The chocolate chips will melt slightly during baking, creating pockets of molten chocolate in every bite.
Bake in Two Layers for Even Cooking
Preheat your oven to 350°F. Divide the batter evenly between two 8-inch round cake pans lined with parchment paper and lightly greased with butter. The pans should be filled about two-thirds full—this prevents the cakes from overflowing and ensures even baking. Tap the pans gently on the counter to remove any air bubbles that may have formed during mixing.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The cakes should spring back slightly when pressed in the center. Here's where it gets tricky—gluten-free cakes can dry out more quickly than traditional cakes, so don't overbake. Remove them from the oven and let them cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Pro Tips For Making Bob'S Red Mill 1 To 1 Chocolate Cake
- Weigh Your Butter: This recipe demands precision—don’t eyeball it. Softened butter (68°F) should yield to gentle finger pressure but not leave greasy prints. I learned this the hard way when my cake turned greasy instead of moist; a kitchen scale guarantees consistency every time.
- Sift the Gluten-Free Flour: Gluten-free baking flour clumps like a stubborn snowdrift. Sift it directly into your mixing bowl before adding dry ingredients—this prevents lumps and ensures even distribution. Trust me, your cake’s texture will thank you.
- Room-Temp Eggs Only: Cold eggs from the fridge won’t blend smoothly and can cause a dense, uneven crumb. Let them sit in warm water for 10 minutes first—this makes all the difference when creaming with butter and sugar.
- Bake with a Water Bath: Gluten-free cakes dry out fast. Place your cake pan in a larger roasting pan filled with 1 inch of hot water before baking. It keeps the center moist longer and prevents cracking—yes, even if you’re skeptical.
Storing and reheating this bob's red mill 1 to 1 chocolate cake
Room-Temp Storage
This cake stays wonderfully moist at room temperature for 3-4 days when wrapped tightly in plastic wrap or stored in an airtight container. I like using glass cake carriers from Pyrex—they keep the cake fresh while letting me admire those perfect layers.
For extra protection, add a paper towel between the layers to absorb any excess moisture. 💫
Fridge Preservation
If you need to store it longer, the fridge is your best friend. Wrap the cake layers individually in plastic wrap, then place them in a sealed container for up to 5 days.
The cold slows moisture loss, but I always bring it to room temperature before serving—cold cake can taste bland. Pro tip: Reheat slices in the microwave for 10-15 seconds to restore that warm-from-the-oven feel.
Freezer-Friendly Layers
Freezing is where this cake really shines for future birthdays or holidays. Wrap each 8-inch layer tightly in plastic wrap, then place them in a freezer bag with all the air squeezed out. Label with the date—these layers keep perfectly for up to 3 months.
When ready to serve, thaw overnight in the fridge. The texture remains just as tender as fresh-baked, though you might want to add a bit more frosting to compensate for any moisture loss during freezing.
Reheating Slices
For that freshly baked experience, reheat individual slices in a 350°F oven for 5-7 minutes on a wire rack. This method prevents sogginess better than the microwave.
If you're short on time, the microwave works too—just cover the slice with a damp paper towel and heat on 50% power for 20-30 seconds. Always check the internal temperature reaches 165°F for food safety.
Frosting Flexibility
Store-bought frostings like Betty Crocker chocolate or homemade ganache can be refrigerated separately for up to 1 week. Bring them to room temperature before spreading to avoid cracking the cake layers.
For extra decadence, I like toasting powdered sugar with 1 teaspoon vanilla extract and 1 tablespoon cocoa powder to create a quick, flavorful dusting that stays fresh for days when stored in an airtight shaker. 🍫

Frequently asked questions
Can I make this cake without a stand mixer?
Use a hand mixer or even a sturdy whisk for the creaming stage—just mix the butter and sugar for 5-7 minutes by hand until light and fluffy. For the dry ingredients, use a large bowl and a sturdy wooden spoon to gently fold everything together. The key is patience—take your time to avoid overmixing the gluten-free flour.
Why does the recipe use vinegar?
The 1 tablespoon vinegar reacts with the baking soda to create tiny air pockets, giving the cake its signature tender crumb. It also helps balance the richness of the chocolate and butter. Don't skip it—this is what prevents dryness in gluten-free baking! The flavor disappears completely during baking.
Can I substitute the gluten-free flour with regular all-purpose flour?
Yes, but the texture will be slightly denser. Replace the 2 cups Bob's Red Mill 1:1 flour with 1.75 cups all-purpose flour plus 0.25 cups cornstarch. This mimics the gluten-free blend's lightness. The cake will still be delicious, but you'll lose that perfect moisture we're aiming for with the special flour.
How do I prevent cracks in the cake layers?
Cracks usually happen from overbaking or sudden temperature changes. Remove the cake from the oven when the toothpick test shows just a few moist crumbs, then let it cool in the pan for 10 minutes before transferring. For extra insurance, bake at 325°F instead of 350°F—this gives the center more time to set without overcooking the top.
What's the best way to level the cake layers?
Use a serrated knife or a cake leveler for perfectly even layers. Dip the knife in hot water, wipe it clean, then press firmly at a slight angle to slice through the cake. For a smoother finish, use a cake scraper to smooth the edges after leveling. This makes frosting much easier and gives a professional look!
