All-purpose flour	1 1/2 cups (190 g)
Unsweetened cocoa powder	1/2 cup (45 g)
Chia seeds	3 tablespoons (36 g)
Baking powder	1 teaspoon
Baking soda	1/2 teaspoon
Salt	1/4 teaspoon
Granulated sugar	3/4 cup (150 g)

Ingredient Notes

Chia seeds: Use whole chia seeds for a little texture. They also absorb some of the liquid in the batter, helping contribute to its consistency.

Cocoa powder: Unsweetened cocoa powder works best because the recipe already contains sugar.

Hot coffee: Coffee intensifies the chocolate flavor without making the cake taste strongly of coffee. You can use hot water instead.

Vegetable oil: Oil helps keep the cake moist and tender. A neutral-flavored oil such as canola or sunflower oil works well.

Milk: Whole milk provides a richer texture, but regular milk or an unsweetened plant-based alternative can also be used.

How to Make Chia Seed Chocolate Cake

PIN IT

1. Prepare the oven and pan

Preheat the oven to 350°F (175°C).

Grease a 9-inch round cake pan or an 8-inch square pan. Line the bottom with parchment paper for easier removal.

2. Combine the dry ingredients

In a medium bowl, whisk together the flour, cocoa powder, chia seeds, baking powder, baking soda, and salt.

Make sure the cocoa powder is evenly distributed and break up any lumps.

3. Mix the wet ingredients

In a large bowl, whisk together the sugar, eggs, vegetable oil, milk, and vanilla extract until smooth.

4. Combine the batter

Gradually add the dry ingredients to the wet ingredients.

Stir gently until just combined. Do not overmix.

5. Add the hot liquid

Slowly pour in the hot water or hot coffee while whisking gently.

The batter will become fairly thin. This is normal and helps produce a moist chocolate cake.

6. Let the chia seeds hydrate

Allow the batter to rest for about 5 minutes. This gives the chia seeds a little time to absorb some of the liquid.

7. Bake

Pour the batter into the prepared pan and smooth the surface.

Bake for approximately 30–35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.

8. Cool

Let the cake cool in the pan for about 10–15 minutes.

Carefully transfer it to a wire rack and allow it to cool completely before slicing or decorating.

Tips for Success

• Do not overmix the batter: Stir just until the ingredients are combined.
• Use hot coffee or water: The hot liquid helps bring out the cocoa flavor.
• Let the batter rest briefly: This allows the chia seeds to hydrate slightly.
• Don’t overbake: Remove the cake when a toothpick has a few moist crumbs.
• Cool before decorating: A warm cake can cause frosting or glaze to melt.
• Use good-quality cocoa powder: It makes a noticeable difference in the chocolate flavor.

Easy Variations

Chocolate Chia Cake with Chocolate Chips

Fold 1/2 cup of chocolate chips into the batter before baking for extra chocolate flavor.

Orange Chocolate Chia Cake

Add 1 teaspoon of finely grated orange zest to the wet ingredients. Orange and chocolate make a classic combination.

Chocolate Walnut Cake

Fold 1/2 cup of chopped walnuts or pecans into the batter for added crunch.

Coconut Chocolate Cake

Add 1/3 cup of unsweetened shredded coconut for a subtle coconut flavor.

Simple Chocolate Glaze

Once the cake has cooled, drizzle it with a simple mixture of melted chocolate and a little warm milk or cream.

Serving Suggestions

Serve slices of Chia Seed Chocolate Cake with:

• Fresh strawberries or raspberries
• Whipped cream
• Greek yogurt
• Vanilla ice cream
• Powdered sugar
• Fresh berries and a light chocolate drizzle

For an elegant dessert, dust the cooled cake with powdered sugar and add a few fresh berries around the serving plate.

Storage

Store the cooled cake in an airtight container at room temperature for up to 2 days.

For longer storage, refrigerate it for up to 4 days. Let refrigerated slices sit at room temperature for a few minutes before serving for a softer texture.

Freezing

Wrap individual slices tightly in plastic wrap and place them in a freezer-safe container or bag.

Freeze for up to 2 months. Thaw overnight in the refrigerator or for several hours at room temperature.

Frequently Asked Questions

Do chia seeds need to be soaked before making the cake?

No. The chia seeds can be added directly to the batter. Allowing the batter to rest for a few minutes gives them some time to absorb liquid.

Can I use ground chia seeds?

Yes. Ground chia seeds will create a smoother texture and distribute more evenly throughout the cake.

Can I use water instead of coffee?

Absolutely. Hot water works perfectly. Coffee simply adds depth to the chocolate flavor.

Can I use plant-based milk?

Yes. Unsweetened almond, oat, or soy milk can be used in place of regular milk.

Why is my cake dry?

The most common reason is overbaking. Start checking the cake a few minutes before the recommended baking time and remove it when a toothpick comes out with a few moist crumbs.

Can I make this cake gluten-free?

You can experiment with a quality all-purpose gluten-free flour blend designed for baking. Results may vary depending on the blend.

Does this cake taste strongly of chia seeds?

No. Chia seeds have a relatively mild flavor. The dominant flavor in this recipe is chocolate.
