Ingredients for arrowroot cake
Six core ingredients transform into a restaurant-quality cake that's naturally gluten-free and effortlessly tender.
| Ingredient | Amount | Notes |
|---|---|---|
| Arrowroot Powder 🌾 | 1 cup | Sifted for even distribution |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smooth texture |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for proper creaming |
| Vanilla Extract 🌸 | 2 tbsp | Pure Madagascar bourbon preferred |
| Large Eggs 🥚 | 4 whole | Room temperature for even mixing |
| Unsalted Whole Milk 🥛 | ¾ cup | Room temperature for smooth batter |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | For balanced seasoning |
| Pure Vanilla Bean Seeds 🌿 | 1 whole | Scraped for infused flavor |
| Powdered Sugar 🍚 | ¼ cup | For dusting finished cake |
Arrowroot powder is the star here—Bob's Red Mill or Anthony's Goods brands deliver the finest texture. The key is sifting it thoroughly to prevent clumping, which can create dense pockets in the cake. For the butter, Plugrá or European-style brands work best due to their higher fat content, ensuring that signature tender crumb. The vanilla bean seeds add a depth that pure extract can't match—split one lengthwise and scrape the seeds directly into the batter. If you can't find vanilla beans, Madagascar bourbon extract is the next best option, but the seeds elevate it to another level entirely.
No arrowroot powder? Tapioca starch at the same weight works in a pinch, though the texture will be slightly denser. Substituting butter for vegan butter or coconut oil maintains moisture but may alter the cake's delicate structure. For the milk, almond or oat milk can replace whole milk, though the cake will be slightly less rich. The powdered sugar can be swapped for confectioners' sugar from any brand, but sifting is crucial to avoid graininess. If you're scaling this recipe, remember that arrowroot absorbs liquid differently than flour—reduce milk by 1 tbsp per cup of arrowroot if increasing the batch size.
Store the baked cake in an airtight container with a slice of bread to maintain moisture for up to 5 days at room temperature. For longer storage, wrap individual slices in plastic wrap and freeze for up to 3 months. The cake reheats beautifully—warm slices in a 200°F oven for 5-7 minutes to restore its softness. To prevent drying, avoid refrigerating the cake unless necessary. The vanilla infusion intensifies over time, making this cake even more aromatic after 24 hours of resting.

Step-by-step instructions for arrowroot cake with vanilla infusion
This method delivers a delicate, cloud-like texture with intense vanilla flavor—every technique matters.
Prepare the Vanilla Infusion and Cream Butter and Sugar
Begin by splitting the whole pure vanilla bean lengthwise and scraping out the seeds using the back of a knife. Add the seeds to the 2 tablespoons vanilla extract in a small bowl and let steep for 10 minutes—this intensifies the vanilla flavor throughout the cake. In a stand mixer fitted with the paddle attachment, beat the 0.75 cup cold, cubed unsalted butter with the 1.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy.
The butter should nearly double in volume and become pale, with ribbons forming when the paddle is lifted. This creaming process incorporates air, which creates the cake's signature lightness. Don't rush this step—properly creamed butter prevents a dense, heavy texture. If your kitchen is warm, chill the butter for 20 minutes before starting to ensure proper creaming.
Incorporate Eggs and Dry Ingredients
Add the 4 room-temperature large eggs one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Scrape down the sides of the bowl to ensure even mixing. Add the infused vanilla mixture and mix for 30 seconds until combined. In a separate bowl, whisk together the 1 cup sifted arrowroot powder, 0.5 teaspoon Diamond Crystal kosher salt, and set aside.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined—you should still see small streaks of flour. Overmixing develops gluten in the arrowroot, which can make the cake dense. The batter should be smooth and slightly thick, like heavy pudding. If it appears too stiff, add 1-2 tablespoons unsalted whole milk to loosen it.
Fold in Milk and Prepare the Pan
Add the 0.75 cup room-temperature unsalted whole milk to the batter in a slow, steady stream while mixing on low speed until fully incorporated. The batter should be smooth and glossy, with no visible streaks. Preheat your oven to 350°F and grease an 8-inch round cake pan generously with butter, then dust with arrowroot powder. Tap the pan against the counter to remove any excess powder.
Pour the batter into the prepared pan and smooth the top with a spatula. The batter should fill the pan about ¾ full. Place the pan on a baking sheet lined with parchment paper to catch any potential spills. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean and the edges are lightly golden. Avoid opening the oven door during baking—this causes the cake to sink.
Cool and Dust with Powdered Sugar
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, invert the cake onto a wire rack and peel off the parchment paper. Allow it to cool completely before dusting with the 0.25 cup powdered sugar using a fine-mesh sieve. The cake will be delicate when fully cooled, so handle it gently to avoid crumbling.
Serve slices at room temperature for the best texture. The cake's light, airy crumb and intense vanilla flavor make it perfect for afternoon tea or dessert. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. For longer storage, freeze slices wrapped in plastic wrap for up to 3 months.
Pro Tips For Making Arrowroot Cake
- Sift the Arrowroot: Mixing dry ingredients with arrowroot powder often leaves clumps—especially if you’re using it straight from the bag. Sift it directly into your bowl with the sugar and flour (if using) before adding wet ingredients. I learned this the hard way when my first cake had a weird, grainy texture.
- Cream Butter and Sugar Slowly: Arrowroot cakes rely on a tender crumb, so don’t rush the butter-sugar mix. Beat them together on medium speed for 2-3 minutes until pale and fluffy—about 100°F (38°C) if you’re measuring with a thermometer. I used to crank it to high and end up with a cake that was dense instead of light.
- Don’t Overmix the Batter: Once you add the eggs and vanilla, mix just until combined—about 20 seconds. Overmixing develops gluten (if you’re using flour) and makes the cake tough. I was guilty of beating it for a full minute, thinking more mixing meant better texture. It doesn’t.
- Use Room-Temp Eggs: Cold eggs add air bubbles that can cause the cake to sink or develop tunnels. Let them sit in warm water for 5 minutes before cracking, or take them straight from the fridge and let them sit out for 30 minutes. My grandmother swore by this, and her arrowroot cakes were always perfectly domed.

Frequently asked questions
Why does this arrowroot cake turn out so light compared to flour-based cakes?
Arrowroot powder creates a delicate, airy texture because it absorbs liquid differently than flour. When combined with proper creaming techniques, it forms a fine, velvety crumb that's naturally gluten-free. The key is sifting the arrowroot thoroughly and avoiding overmixing to prevent density.
Can I substitute arrowroot powder with cornstarch or tapioca?
Yes, but with adjustments! Use the same amount of tapioca starch, but expect a slightly denser texture. Cornstarch works in a pinch (1:1 ratio), though arrowroot's natural gelling properties create the signature lightness. For best results, stick with arrowroot powder for that signature tender crumb.
How do I prevent my arrowroot cake from cracking on top?
Cracking usually happens from uneven baking. Ensure your oven is fully preheated to 350°F and place the cake pan on the middle rack. Avoid opening the oven door during baking, and bake until a toothpick comes out clean. For extra insurance, dust the pan with more arrowroot powder before pouring the batter.
Is this cake gluten-free? Can I make it vegan?
This recipe is naturally gluten-free! For a vegan version, replace the butter with vegan butter or coconut oil and use flax eggs (1 tbsp ground flax + 3 tbsp water per egg). The milk can be swapped for almond or oat milk, though the texture may be slightly less rich.
How long should I let the cake cool before slicing?
Let the cake cool completely in the pan for 10 minutes, then invert onto a wire rack. Wait at least 1 hour before slicing to allow the arrowroot to fully set. This prevents crumbling and ensures clean cuts for delicate layers.
