What You’ll Need
For the Cake:
- 2 cups (280g) gluten-free flour blend – Use a blend with rice flour base for best results
- 1 teaspoon xanthan gum – Only if your flour blend doesn’t include it
- 1½ cups (300g) granulated sugar – Caster sugar works equally well
- ½ cup (115g) unsalted butter, softened – Can substitute with dairy-free butter
- 3 large eggs, room temperature – Critical for proper emulsification
- 1 cup (240ml) whole milk – Or your favorite plant-based milk
- 2 teaspoons baking powder – Ensure it’s gluten-free certified
- 1 teaspoon vanilla extract – Pure vanilla gives the best flavor
- ½ teaspoon salt – Enhances all flavors and balances sweetness
For Cream Cheese Frosting:
- 8 oz (225g) cream cheese, softened – Must be room temperature
- ¼ cup (55g) unsalted butter, softened – Also room temperature
- 3 cups (360g) powdered sugar, sifted – Sifting prevents lumps
- 1 teaspoon vanilla extract – Complements the cake perfectly
- 2-3 tablespoons milk – For desired consistency
Essential Notes:
- Check your flour blend: If it already contains xanthan gum, skip adding more
- Gluten-free certification: Ensure all ingredients are certified gluten-free
- Xanthan gum quality: Bob’s Red Mill or Anthony’s are reliable brands
Step-by-Step Directions
- Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans with butter or oil, then dust with gluten-free flour. Line bottoms with parchment paper for extra insurance against sticking.
- Check your flour blend for xanthan gum content. Most commercial blends include it, but if yours doesn’t, you’ll need to add 1 teaspoon. Never add xanthan gum if your blend already contains it—this creates gummy, inedible cake.
Critical tip: Too much xanthan gum ruins texture completely. When in doubt, err on the side of less rather than more.
- Whisk together dry ingredients in a large bowl: flour blend, xanthan gum (if needed), baking powder, and salt. Whisk thoroughly to distribute the xanthan gum evenly—clumps will create uneven texture.
- Cream butter and sugar in a separate large bowl using an electric mixer on medium speed. Beat for 3-4 minutes until light, fluffy, and noticeably paler. This step is crucial for cake structure in gluten-free baking.
- Add eggs one at a time, beating well after each addition. The mixture may look slightly curdled—this is normal with gluten-free batters. Beat in vanilla extract until combined.
- Alternate wet and dry ingredients. Add one-third of the flour mixture to the butter mixture, beat until just combined. Add half the milk, beat briefly, then another third of flour, remaining milk, and final flour portion. Mix only until just combined—overmixing activates xanthan gum too much.
- Rest the batter for 5 minutes. This allows the xanthan gum and flour to hydrate properly, resulting in better texture. The batter will thicken slightly during this time.
- Divide batter evenly between prepared pans. Use kitchen scales for accuracy, or eyeball it and smooth tops with an offset spatula. Tap pans gently on counter to release air bubbles.
- Bake for 28-32 minutes until centers spring back when lightly touched and a toothpick inserted in the center comes out clean or with just a few moist crumbs. Gluten-free cakes can go from perfect to dry quickly, so watch carefully.
- Cool in pans for 15 minutes, then turn out onto wire racks to cool completely. Gluten-free cakes are more fragile when warm, so patience is key here.
- Make frosting while cakes cool. Beat cream cheese and butter until smooth and fluffy. Gradually add powdered sugar, beating until smooth. Add vanilla and enough milk to reach spreading consistency.
- Assemble your cake once completely cool. Place one layer on serving plate, spread with frosting, top with second layer, and frost top and sides as desired.
How to Serve
This xanthan gum cake is delicious served at room temperature, allowing the flavors to fully develop. Cut clean slices using a sharp knife wiped between cuts—gluten-free cakes can be slightly more delicate than traditional cakes.
Pair with fresh berries for a burst of color and acidity that complements the rich vanilla flavor. A cup of coffee or tea alongside makes this perfect for afternoon gatherings or casual dinner parties.
For special occasions, consider adding food coloring to the frosting or decorating with fresh flowers. The cake’s neutral vanilla flavor pairs beautifully with seasonal fruits—strawberries in spring, peaches in summer, or spiced pears in fall.
This cake also freezes beautifully, making it perfect for meal prep or advance party planning. Wrap individual slices for easy grab-and-go treats.
Expert Tips for Success
Measuring matters more in gluten-free baking: Use kitchen scales when possible. Gluten-free flours vary significantly in weight per cup, and precision ensures consistent results every time.
Room temperature ingredients are non-negotiable: Cold ingredients don’t emulsify properly in gluten-free batters, leading to dense, heavy cake. Plan ahead and bring everything to room temperature before starting.
Don’t skip the resting period: Allowing the batter to rest gives the xanthan gum time to hydrate and the flour to absorb moisture properly. This simple step dramatically improves texture.
Storage specifics: Store covered at room temperature for up to 3 days, or refrigerate for up to a week. Gluten-free cakes actually improve after a day as the crumb sets and flavors meld.
Altitude adjustments: At high altitudes, reduce baking powder by ¼ teaspoon and increase liquid by 2-3 tablespoons. The lower air pressure affects gluten-free batters differently than traditional ones.
Flavor variations: This base recipe accepts additions beautifully. Try lemon zest and juice for citrus cake, cocoa powder for chocolate (reduce flour by ¼ cup), or almond extract for subtle nuttiness.
Professional secret: A tablespoon of apple cider vinegar added with the wet ingredients creates extra tenderness and helps the cake rise beautifully.
Common Questions
What if my flour blend already contains xanthan gum?
Never add additional xanthan gum if your blend includes it. Check the ingredient list carefully—most commercial blends like King Arthur or Bob’s Red Mill 1-to-1 already contain the perfect amount.
Can I substitute the xanthan gum with something else?
Guar gum works as a 1:1 substitute, though the texture will be slightly different. Psyllium husk powder can work (use ½ teaspoon) but may add a slight purple tint. Avoid cornstarch or arrowroot as direct substitutes.
Why is my cake gummy or dense?
This usually results from too much xanthan gum or overmixing. Measure xanthan gum carefully using measuring spoons, not eyeballing, and mix batter only until ingredients are just combined.
Can I make cupcakes with this recipe?
Absolutely! This batter makes about 18 cupcakes. Bake at 350°F for 18-22 minutes until tops spring back. They’re perfect for portion control and freeze beautifully.
How do I know if my baking powder is gluten-free?
Always check labels—some baking powders contain wheat starch. Brands like Clabber Girl, Rumford, and Bob’s Red Mill clearly label their gluten-free options.
My cake fell in the center—what happened?
This often indicates underbaking, too much liquid, or opening the oven door too early. Gluten-free cakes need the full baking time to set properly, and temperature fluctuations can cause collapse.
