Amaranth Cake Recipe: Nutty Grain Magic with Moist Layers

Amaranth cake transforms this ancient grain into a surprisingly moist, nutty dessert that rivals traditional flour-based cakes. 🌟 The secret lies in balancing amaranth’s earthy richness with flaxseed binders and plant-based milk for a tender crumb—no dairy or eggs required. I’ve perfected this recipe after years of experimenting with gluten-free baking, ensuring every slice delivers that perfect balance of texture and flavor.

What sets this apart is how the amaranth grain’s natural nuttiness shines through while keeping the cake incredibly moist—no dry, crumbly results here. The recipe uses simple pantry staples like flaxseed meal for binding and coconut oil for richness, making it accessible for any home baker. Baking at 350°F for 40-45 minutes ensures a golden top with a tender interior, even when using whole amaranth flour.

The result is a cake with layers of subtle sweetness and nutty depth, perfect for brunch or dessert. Top it with a light coconut whipped cream or fresh berries to elevate the presentation. This recipe proves vegan baking can be just as indulgent as traditional desserts—without compromising on moisture or flavor.

Whether you're gluten-free, vegan, or simply curious about amaranth, this cake delivers restaurant-quality results with minimal effort. Let’s get baking!

Ingredients for amaranth cake

Eight simple ingredients transform amaranth flour into a moist, nutty cake that rivals traditional desserts.

The amaranth flour is the heart of this recipe, and Bob's Red Mill or Anthony's Goods brands deliver the finest grind for a smooth texture. Look for finely ground flour—coarse particles can create a gritty cake. If you can't find pre-ground amaranth, pulse whole amaranth grains in a high-speed blender until ultra-fine (about 30 seconds). The almond milk should be unsweetened to avoid altering the cake's delicate balance, and Silk or Califia Farms brands work perfectly. For the coconut oil, Virgins brand is a reliable choice, though any organic brand will suffice. The flaxseed meal must be freshly ground to maximize its binding properties—store-bought pre-ground meal works, but grinding your own from whole flaxseeds yields superior results.

No almond milk? Oat milk or soy milk are excellent substitutes, though they may slightly alter the texture. Running short on maple syrup? Agave nectar or date syrup work in a 1:1 ratio, though maple syrup's distinct flavor is ideal here. The blueberries are optional but add a lovely contrast—use frozen if fresh isn't available, but don't thaw them first. For a richer cake, substitute half the almond milk with cashew milk, which adds a subtle creaminess. The coconut whipped cream can be made with coconut cream chilled overnight and whipped with a pinch of maple syrup, or use store-bought vegan whipped topping for convenience. If you prefer a chocolate twist, add 2 tablespoons of cocoa powder to the dry ingredients.

This cake keeps beautifully for 5 days in an airtight container at room temperature, though it's best enjoyed within 3 days for optimal moisture. For longer storage, wrap individual slices in plastic wrap and freeze for up to 3 months. The cake reheats wonderfully—wrap a slice in a damp paper towel and microwave for 15 seconds to restore freshness. Store the coconut whipped cream in the fridge and whip it again before serving, as it tends to separate. The flaxseed meal should be kept in a cool, dark place to prevent rancidity, and the amaranth flour can be stored in the freezer for extended freshness if you bake frequently.

Step-by-step instructions for amaranth cake

This method ensures a perfectly moist, nutty cake with tender layers and balanced sweetness.

In a small bowl, whisk together the 0.25 cup flaxseed meal and 0.25 cup almond milk until completely combined. Let this mixture sit for 5 minutes until it thickens into a gel-like consistency. This is your egg substitute, providing the necessary binding for the cake's structure. The flax mixture should resemble raw egg whites in texture—if it's too thin, add another ½ teaspoon of flaxseed meal.

I always prepare this first because it needs time to thicken properly. The flaxseed meal activates when mixed with liquid, creating a natural binder that holds the cake together without eggs. Don't skip the waiting time—rushing this step can result in a cake that collapses during baking.

In a large mixing bowl, combine the 0.5 cup melted coconut oil, 0.5 cup maple syrup, 1 tbsp vanilla extract, and the thickened flax mixture. Whisk vigorously for 2 minutes until the mixture is completely homogeneous. The coconut oil should be fully incorporated, creating a smooth, slightly thick base. Here's the thing—amaranth flour can be dense, so this thorough mixing ensures even distribution of moisture throughout the batter.

Next, add the 1 tbsp apple cider vinegar and whisk again for 30 seconds. The vinegar reacts with the baking soda we'll add later, creating lift in the cake. The mixture might look curdled at first, but that's normal—it will smooth out when we add the dry ingredients. This is where the cake's tenderness begins to develop.

In a separate bowl, sift together the 1.5 cups amaranth flour, 0.5 tsp baking soda, 0.25 tsp salt, and 1 tsp cinnamon. This sifting step is crucial—it prevents lumps in the final batter and ensures even distribution of the leavening agents. Gradually add this dry mixture to the wet ingredients while whisking on low speed for 1 minute.

Be careful not to overmix—just until the batter comes together. You'll see some flour streaks remain, and that's perfect. Overmixing develops gluten in the amaranth flour, which can make the cake dense. The ideal batter should be thick but pourable, like heavy pudding. If it's too thick, add 1-2 tablespoons of almond milk to achieve the right consistency.

Gently fold in the 1 cup fresh blueberries using a silicone spatula, being careful not to crush them. You want to distribute them evenly throughout the batter without breaking too many—this preserves their juicy bursts in each bite. The blueberries should be spread throughout, with just a few visible on the surface for aesthetic appeal.

Preheat your oven to 350°F and grease two 6-inch round cake pans or one 9-inch round pan thoroughly with coconut oil. Line the bottoms with parchment paper circles for easy removal. The pans should be prepared while the oven heats up—this prevents the batter from sticking to the sides as it bakes.

Divide the batter evenly between your prepared pans. For round pans, fill them about ⅔ full—amaranth cakes rise moderately but shouldn't overflow. Bake in the preheated oven for 30-35 minutes until a toothpick inserted into the center comes out clean and the edges are lightly golden. The top should be springy to the touch but not sticky.

I know it's tempting to check early, but resist the urge. Amaranth cakes can dry out if overbaked, so rely on the toothpick test rather than time alone. When done, transfer the cakes to a wire rack and let them cool in the pans for 10 minutes before removing. This gradual cooling prevents cracking and helps maintain moisture. Serve with 1 cup coconut whipped cream for a luscious vegan topping.

Perfect pairings for this recipe

Fruit Compote

Pair your amaranth cake with a warm berry compote made from 1 cup mixed berries (fresh or frozen), 2 tbsp maple syrup, and 1 tsp lemon juice. Simmer for 8-10 minutes until thickened, then drizzle over each slice. The tart-sweet contrast cuts through the cake’s nuttiness beautifully. I love using blackberries or raspberries for their deep flavor, but strawberries work too. 🍓

Coconut Whipped Cream

For a vegan-friendly topping, whip 1 cup chilled coconut cream (from a can of full-fat coconut milk) with 1 tbsp maple syrup and a pinch of salt until fluffy. Fold in ½ tsp vanilla extract for extra depth. This light, airy topping balances the cake’s density and adds a tropical twist. Store-bought So Delicious coconut whipped cream is a quick alternative if you’re short on time. 🥥

Spiced Nuts

Add crunch and warmth with a simple spiced nut topping. Toast ½ cup chopped walnuts or pecans in a dry pan over medium heat for 3-4 minutes, then toss with ½ tsp cinnamon, ¼ tsp cayenne, and 1 tsp maple syrup. Let cool before sprinkling over cake slices. The nuts amplify the amaranth’s nuttiness while adding texture. 🌰
