Ingredients for anna olson vanilla cake
Twelve ingredients for a cake that'll make your taste buds do a happy dance every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 ¼ cups | White or light brown |
| Buttermilk 🥛 | 1 ½ cups | Room temperature preferred |
| Vegetable Oil 🫒 | 1 cup | Light or canola preferred |
| Pure Vanilla Extract 🌿 | 2 tbsp | High-quality, not imitation |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Bean Seeds 🍃 | 1 whole | Scraped from 1 pod |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for frosting |
| Powdered Sugar 🍚 | 4 cups | Sifted for smooth frosting |
| Cream Cheese 🧀 | 8 oz | Room temperature, full-fat |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for whipping |
The flour is non-negotiable here—King Arthur or Gold Medal are my go-tos for that perfect crumb. Vanilla bean seeds? Trader Joe's sells them pre-scraped, but if you've got a whole pod, scrape it yourself for that authentic aroma. The buttermilk needs to be room temperature—cold buttermilk curdles when mixed with oil. For the frosting, Land O'Lakes butter and Creamette cream cheese are my trusted brands—they give that professional texture. Pro tip: measure your powdered sugar after sifting—it packs down surprisingly.
No buttermilk? Mix 1.5 tbsp vinegar or lemon juice with 1.5 cups milk and let sit for 5 minutes. Vanilla extract running low? Vanilla bean paste works in a pinch, but it's thicker, so adjust to taste. Swapping oils? Avocado oil has a higher smoke point and similar texture. For the frosting, if you're avoiding dairy, vegan butter and coconut cream work beautifully—just add a splash of vanilla to compensate. The cream cheese should be at room temperature when mixing, or you'll end up with lumps. Trust me on this one.
Flour and powdered sugar keep best in airtight containers in a cool, dark place for up to 6 months. The vanilla extract lasts 1 year unopened, 6 months after opening. For the frosting, make it a day ahead—flavors meld beautifully. Store leftovers in the fridge for 5 days, covered tightly. The cake itself? Wrapped in plastic, it stays moist for 3 days at room temperature, or freeze slices for 3 months. I always bake an extra layer—because why not?

Step-by-step instructions for Anna Olson's vanilla cake
Here's how to create Anna Olson's signature ultra-moist vanilla cake with perfect layers and velvety frosting.
👨🍳 Step 1: Prepare the Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans, then line the bottoms with parchment paper. In a medium bowl, whisk together the 3 cups all-purpose flour, 2.25 cups granulated sugar, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients together to ensure a light, airy texture—this prevents dense layers.
In a separate large bowl, combine the 1.5 cups buttermilk, 1 cup vegetable oil, 2 tbsp pure vanilla extract, and the vanilla bean seeds scraped from 1 pod. Add the 2 whole large eggs one at a time, whisking gently after each addition. Gradually fold the dry ingredients into the wet mixture until just combined—you should still see small flour streaks. Overmixing develops gluten, which can make the cake tough.
🍳 Step 2: Bake the Layers
Divide the batter evenly between the prepared cake pans. Tap each pan gently on the counter to release any air bubbles. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The edges should be golden brown, but the tops may still look slightly underdone—they'll firm up as they cool.
Here's the thing—don't open the oven door during the first 20 minutes of baking. The sudden temperature drop can cause the cakes to sink. Let them bake undisturbed until they pass the toothpick test. Once done, remove from the oven and let them cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
🥘 Step 3: Make the Vanilla Bean Frosting
While the cakes cool, prepare the frosting by beating the 1 cup cold unsalted butter in a stand mixer fitted with the paddle attachment until smooth and creamy. Gradually add the 4 cups powdered sugar and mix on low speed until combined. Increase the speed to medium and beat for 2-3 minutes until light and fluffy.
In a separate bowl, beat the 8 oz room-temperature cream cheese until smooth. Add it to the butter-sugar mixture along with the 1 cup cold heavy whipping cream and the remaining 1 tbsp pure vanilla extract. Beat on high speed for 3-4 minutes until the frosting is thick, smooth, and holds its shape when piped. This is the moment that matters—if the frosting is too soft, chill it for 15 minutes before assembling the cake.
🍽️ Step 4: Assemble the Cake
Once the cakes are completely cool, level the tops if necessary using a serrated knife. Place the first layer on a cake stand or plate and spread a thin layer of frosting on top to create a "crumb coat." This prevents crumbs from getting into the final frosting layer. Chill the cake for 10 minutes in the refrigerator.
Remove the cake from the fridge and apply the remaining frosting, starting with the sides. Use a spatula to smooth the frosting evenly, creating a slight overhang at the edges. Place the second layer on top and gently press down. Frost the top layer, then pipe decorative rosettes or swirls around the edges for a professional finish. The frosting should be smooth and glossy, with no visible lumps or streaks.
Pro Tips For Making Anna Olson Vanilla Cake
- MEASURE BUTTERMILK ACCURATELY: This isn’t the kind of recipe where you eyeball sour cream substitutes—use a liquid measuring cup for the buttermilk. I learned this the hard way when my cake turned out dense because I guessed and came up short. The buttermilk’s acidity and fat content are non-negotiable for that classic Anna Olson texture.
- WHISK DRY INGREDIENTS FIRST: Combine the flour, baking powder, and salt before adding any wet ingredients. This ensures even distribution of leavening, which is especially important in a one-bowl recipe where you’re not sifting. I used to dump everything in at once, and the cake would rise unevenly—now it’s smooth and consistent.
- DON’T OVERMIX THE BATTER: Stop mixing as soon as the flour disappears—about 20 seconds after the last dry ingredient is incorporated. Overmixing develops gluten, which makes the cake tough. I was skeptical until I tried it: the difference between a tender crumb and a slightly chewy one is that extra 10 seconds of beating.
- USE A TOOTHPICK TEST: Insert a toothpick into the center of the cake after baking—if it comes out clean, it’s done. If not, give it 5–10 more minutes. I’ve seen recipes say "bake until golden," but this method is foolproof, especially since Anna Olson’s recipe relies on chemical leaveners more than steam. No guesswork.
Perfect pairings for this anna olson vanilla cake
Creamy Coffee Pairings
This cake practically begs for a cup of coffee to cut through its richness. A medium-roast Colombian coffee with its balanced acidity and chocolate notes enhances the vanilla's natural sweetness. I love brewing Starbucks Sumatra or Peet's Major Dickason's Blend—both highlight the cake's subtle vanilla bean aroma. For an iced twist, try cold brew concentrate mixed with vanilla syrup and a splash of heavy cream for a dessert-like drink. ☕
Tea Time Elegance
Earl Grey tea elevates this cake to afternoon tea perfection. The bergamot's citrusy brightness contrasts beautifully with the cake's buttery frosting. Steep Twinings Earl Grey for 4-5 minutes and serve with a slice of cake for a sophisticated pairing. For a creamy option, try chai latte—the warm spices complement the vanilla without overpowering. A hot toddy with vanilla syrup and a cinnamon stick is my go-to winter pairing. 🍵
Seasonal Fruit Companions
Fresh berries add vibrant color and acidity that balances the cake's sweetness. Strawberries macerated in honey and lime juice create a perfect summer pairing. In fall, roasted figs with a drizzle of balsamic glaze add depth. For winter, candied citrus peel (orange or lemon) provides a zesty contrast. I always keep raspberries on hand—their tartness cuts through the frosting beautifully. 🍓
Boozy Upgrades
A splash of vanilla-infused bourbon (like Buffalo Trace) in your coffee or tea adds warmth that pairs wonderfully with the cake. For a cocktail pairing, try a Vanilla Bean Martini—mix 2 oz vodka, 1 oz vanilla syrup, and ½ oz coffee liqueur with ice. A Baileys Irish Cream drizzle over the cake adds decadence without overwhelming. For wine lovers, a sweet Moscato with its floral notes enhances the vanilla's aroma. 🍸
Spiced Warm Drinks
Cinnamon and nutmeg spices in warm drinks complement the cake's vanilla perfectly. A hot chocolate made with Ghirardelli squares and a pinch of cayenne adds a subtle kick. For something herbal, vanilla chai with cardamom and ginger creates a cozy pairing. I also love mulled wine in winter—simmer red wine, orange peel, and cloves for 10 minutes before serving. The spices echo the cake's warm vanilla notes. 🍷

Frequently asked questions
Can I make this vanilla cake without buttermilk?
Mix 1.5 tbsp vinegar or lemon juice with 1.5 cups milk and let it sit for 5 minutes to create a buttermilk substitute. This keeps the cake's signature moist texture without altering the flavor. Just be sure to use room-temperature milk for best results.
Why does the frosting turn grainy?
Grainy frosting usually means the ingredients weren't properly mixed or the butter wasn't cold enough. Always beat the 1 cup cold butter until smooth before adding powdered sugar, and make sure your cream cheese is room temperature. If it happens, try adding 1 tsp lemon juice to dissolve any sugar crystals.
How do I store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for 3 days—it stays moist this way. For longer storage, slice and freeze individual portions for up to 3 months. The frosting can be refrigerated separately for 5 days if you're making it ahead.
Can I make this cake in a bundt pan?
This recipe is designed for two 9-inch round layers, but you could adapt it! Use a 10-inch bundt pan and reduce the batter by 25%. The baking time will be about 40-45 minutes, and you'll need to adjust the frosting quantity to cover the shape properly. Test with a toothpick for doneness.
What makes this cake different from other vanilla cakes?
The magic comes from the vanilla bean seeds and the cream cheese frosting—both add depth that regular vanilla extract can't match. The buttermilk and vegetable oil combo creates ultra-moist layers without being heavy, while the frosting's tanginess balances the sweetness perfectly. It's a professional-level texture at home!
