How to Make This Eggless Chia Seed Cake
Follow these simple steps to bake your high-protein eggless chia seed cake to perfection.
- Preheat the oven to 350°F (175°C). Lightly grease and flour a 9×9-inch square cake pan or use an 8×8-inch pan for a slightly taller cake. A round 8- or 9-inch pan also works well.
- Prepare the dry mix. In a medium bowl, whisk together the whole wheat flour, baking powder, baking soda, salt, chia seeds, cinnamon, and nutmeg. This blend creates the cake’s structure and ensures even rise.
- Make the wet mix. In a large mixing bowl, combine the sugar, coconut oil, and applesauce. Whisk until smooth. Stir in the mashed bananas and vanilla extract. These add moisture and natural sweetness to your eggless chia seed cake.
- Combine the mixtures. Gradually add the dry ingredients to the wet mix. Stir gently until just combined. Avoid overmixing to keep the cake soft and airy.
- Transfer to the pan. Pour the batter into your prepared cake pan and smooth the top using a spatula.
- Mix the crumb topping. In a small bowl, combine the flour, sugar, and coconut oil for the topping. Use a fork or your fingers to create a crumbly texture. Sprinkle evenly over the batter.
- Bake. Place the pan on the center oven rack and bake for 30 to 35 minutes. The cake is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs.
- Cool and serve. Let the cake cool in the pan for 10 minutes before transferring to a wire rack. Slice once fully cooled and enjoy a moist, flavorful slice packed with plant-powered protein.
This method ensures every bite of your eggless chia seed cake comes out soft, nutritious, and satisfying.

Expert Tips and Substitutions
Make your eggless chia seed cake even better with these tried-and-true tips and simple swaps that work for different preferences and dietary needs.
Tip 1: Don’t Overmix the Batter
Once you combine wet and dry ingredients, stir just until no flour streaks remain. Overmixing can make the cake dense instead of light and fluffy.
Tip 2: Let the Batter Rest Before Baking
Allow the batter to sit for 5 to 10 minutes before pouring it into the pan. This gives the chia seeds time to absorb moisture and helps improve the cake’s texture.
Flour Substitutions
You can replace whole wheat pastry flour with all-purpose flour for a lighter texture. For a grain-free option, almond flour works, but you’ll need to reduce moisture slightly since it absorbs liquids differently.
Vegan Option
To make this eggless chia seed cake completely vegan, use a high-protein plant-based yogurt like soy or coconut yogurt in place of Greek yogurt if you add it. Also, choose a vegan-friendly protein powder to keep the recipe 100% plant-powered.
Oil Choices
Coconut oil gives a subtle richness, but any neutral oil like sunflower, avocado, or canola can be used.
These adjustments let you tailor the recipe without compromising the taste or protein content.
