Ingredients for arrowroot cake
Eight essential ingredients transform into a signature light-as-air arrowroot cake with lasting moisture.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Arrowroot Powder 🌾 | ½ cup | Not cornstarch substitute |
| Granulated White Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Large Eggs 🥚 | 4 whole | Room temperature for even mixing |
| Unsalted Butter 🧈 | 1 cup | Softened to room temperature |
| Pure Vanilla Extract 🌿 | 2 tsp | Bottled vanilla preferred |
| Baking Powder 🍞 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Lemon Zest 🍋 | 1 tbsp | Freshly grated for brightness |
| Vegetable Oil 🫒 | ¼ cup | Light for tender crumb |
Arrowroot powder is the star here—Bob's Red Mill or Arrowroot USA brands deliver the purest quality. Avoid cornstarch substitutes; arrowroot creates that signature tender crumb. For the flour, King Arthur or Gold Medal brands work best due to their consistent protein content. The butter should be European-style if possible for richer flavor, though standard unsalted works fine. Room temperature ingredients mix more evenly, so plan ahead if your kitchen runs cold. Superfine sugar dissolves faster, but regular granulated sugar works if pulsed briefly in a food processor.
No arrowroot powder? Tapioca starch at double the amount mimics the texture, though results won't be identical. Short on vanilla? Vanilla bean paste adds flecks for visual appeal, or use vanilla sugar at half the quantity. The milk can be swapped for heavy cream for extra richness, though texture may shift slightly. Lemon zest can be omitted if unavailable, but orange zest works beautifully as an alternative. For a nutty variation, swap 0.25 cup of flour for finely ground almond flour—just increase the milk by 1 tbsp to maintain moisture balance.
This cake stays moist for 5-6 days when wrapped tightly in plastic. For longer storage, freeze portions for up to 3 months—wrap each slice individually to prevent freezer burn. The vanilla infusion deepens over time, making leftovers even more flavorful. Room temperature cake is ideal for serving, but a 2-minute warm-up in the oven revives texture if chilled. Optional glaze or frosting should be added just before serving to maintain the signature tender crumb.

Step-by-step instructions for arrowroot cake
This method delivers a perfectly moist, tender cake with a delicate crumb.
Prepare the Dry Ingredients
In a medium bowl, sift together the 2 cups all-purpose flour and 0.5 cup arrowroot powder. This step ensures an even distribution of ingredients and prevents lumps in your batter. Add the 2 tsp baking powder and 0.5 tsp salt, then whisk gently to combine. The arrowroot powder is crucial here—it creates that signature light, airy texture that sets this cake apart.
Next, add the 1.5 cups granulated white sugar to the dry mixture. Using superfine sugar will give you a smoother texture, but regular granulated sugar works fine if that's what you have. Whisk everything together until thoroughly combined. This dry mixture will be your base, so take your time to ensure no flour pockets remain.
Cream Butter and Sugar
In a separate large mixing bowl, combine the 1 cup softened unsalted butter and 1.5 cups granulated white sugar. Using an electric mixer on medium-high speed, beat the mixture for 3-5 minutes until it's light and fluffy. You'll notice the mixture nearly doubles in volume and becomes pale in color. This creaming process incorporates air, which helps create the cake's signature tender crumb.
Here's the thing—don't rush this step. The butter should be softened but not melted, and the mixture should look smooth and creamy. If it's too thick, let it sit at room temperature for another 5-10 minutes before continuing. This ensures proper aeration for the perfect texture.
Add Eggs and Infuse Flavors
Add the 4 whole large eggs, one at a time, mixing well after each addition. The mixture will thicken slightly as you incorporate each egg. Once all eggs are added, mix in the 2 tsp pure vanilla extract and 1 tbsp lemon zest. The lemon zest adds a bright citrus note that complements the vanilla beautifully. Stir in the 0.5 cup milk and 0.25 cup vegetable oil until just combined.
At this stage, your batter should be smooth and well-aerated. If it looks slightly curdled, don't worry—this is normal. The dry ingredients will smooth everything out in the next step. The key here is to avoid overmixing, which can develop gluten and make the cake dense.
Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients in 3 additions, mixing on low speed after each addition. This slow incorporation prevents overmixing and helps maintain the cake's tender texture. Once all the dry ingredients are incorporated, mix on low speed for an additional 1-2 minutes just until combined.
You'll notice the batter is thick but pourable. This is exactly what you want for a moist, tender cake. The arrowroot powder will create that signature lightness, while the butter and oil ensure richness. The batter should be smooth with no visible flour streaks, indicating proper mixing.
Bake to Golden Perfection
Preheat your oven to 350°F. Grease and flour two 9-inch round cake pans or line them with parchment paper. Divide the batter evenly between the pans, spreading it out to create an even layer. Tap the pans gently on the counter to remove any air bubbles.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and slightly springy to the touch. Here's the crucial part—don't overbake. The arrowroot cake continues to set as it cools, so it's better to pull it out when it's just slightly underdone.
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. Once cooled, you can frost with your favorite vanilla buttercream or serve plain to appreciate the cake's natural moisture and flavor. This cake stays moist for days, making it perfect for meal prep or special occasions.
Pro Tips For Making Arrowroot Cake
- Whisk Eggs Room-Temp: Mixing cold eggs into your batter can make the cake dense and tough. Let eggs sit out for 30 minutes before cracking them—this way, they blend smoothly and create the light, airy texture arrowroot needs to shine.
- Sift Dry Ingredients First: Arrowroot powder clumps like crazy. Sift the arrowroot and flour together before adding wet ingredients to avoid lumps that’ll ruin your cake’s tender crumb. (Yes, even if you’re in a hurry.)
- Check Doneness with a Toothpick: The cake might look golden but still be undercooked. Insert a toothpick into the center—if it comes out with a few moist crumbs (not wet batter), it’s done. Overbaking dries out arrowroot cakes fast.
- Use Room-Temp Butter: Cold butter creates pockets that won’t melt evenly, leaving your cake greasy in spots. Let the butter sit out until it’s soft but not liquid—about 1 hour at room temperature. (Skip the microwave; it melts too fast.)

Frequently asked questions
Why does arrowroot cake stay moist longer than regular cake?
The arrowroot powder is the secret ingredient—it creates a gel-like texture when combined with liquid, locking in moisture for 5-6 days when properly stored. Unlike cornstarch, arrowroot has a higher binding capacity, preventing dryness that plagues traditional cakes. The butter and oil in the recipe also contribute to that signature tender crumb that resists drying out.
Can I substitute arrowroot powder with cornstarch?
While you can use cornstarch in a pinch, it won't give you the same signature texture. Cornstarch creates a slightly denser crumb and doesn't hold moisture as well. For the best results, use double the amount of cornstarch (1 cup instead of 0.5 cup), but expect a slightly different mouthfeel. True arrowroot fans will notice the difference in tenderness and moisture retention.
How do I tell when the cake is fully baked?
Insert a toothpick into the center—it should come out clean or with just a few moist crumbs. The cake should also spring back slightly when gently pressed in the center. Remember, arrowroot cakes continue setting as they cool, so it's better to pull them out slightly underdone. The top should be golden brown, not dark brown or cracked.
What's the best way to store leftover arrowroot cake?
Wrap the cake tightly in plastic wrap or aluminum foil to preserve moisture. Store at room temperature for up to 5 days, or freeze for 3 months by wrapping each slice individually. For serving, let it sit at room temperature for 30 minutes to restore its tender texture. The vanilla flavor actually improves over time, making leftovers even more delicious.
Can I make this cake in a different pan size?
Yes, but adjust baking time accordingly. For a 8-inch round pan, bake 25-30 minutes; for a 10-inch pan, bake 30-35 minutes. The key is to use the same oven temperature (350°F) and check doneness with a toothpick. Larger pans may require slightly longer baking, while smaller pans might need less time. Always tap the pan gently to release air bubbles before baking.
