How to Make Chia Seed Lemon Cake
Step 1: Preheat the Oven
Set your oven to 350°F (177°C). Lightly grease a 9-by-5-inch loaf pan using olive oil or nonstick spray to prevent sticking.
Step 2: Prepare the Yogurt Mix
In a small bowl, stir together Greek yogurt, chia seeds, 2 tablespoons of lemon juice, and 1 tablespoon of lemon zest. Let this mixture sit while you prepare the other components. This step allows the chia seeds to begin absorbing moisture.
Step 3: Combine the Dry Ingredients
In a medium mixing bowl, whisk the flour, baking soda, and salt until well blended. This ensures even distribution throughout the batter.
Step 4: Whip the Sugar and Oil
Using a hand mixer or stand mixer on high speed, beat the olive oil and granulated sugar until the mixture looks light and smooth. This step should take about 4 minutes. Stir in the vanilla extract.
Step 5: Add the Eggs
Crack the eggs in one at a time, mixing well after each addition. Scrape the sides of the bowl to keep everything smooth and consistent.
Step 6: Build the Batter
Switch to low speed. Add the dry ingredients in three stages, alternating with the yogurt-chia mixture in two stages. Start and end with the dry mix. Mix just until combined. Overmixing can make your chia seed lemon cake dense.
Step 7: Bake the Cake
Pour the batter into the prepared loaf pan. Smooth the surface with a spatula. Bake in the center of the oven for 40 to 45 minutes or until a toothpick inserted in the center comes out clean. The cake should feel springy and the top golden.
Step 8: Cool It Down
Let the cake rest in the pan for 10 minutes. Then, remove it and place it on a wire rack to cool completely before glazing.
Step 9: Make the Glaze
In a small bowl, whisk together powdered sugar, 2 tablespoons lemon juice, and ½ teaspoon lemon zest. Adjust the consistency by adding more sugar or juice as needed until it forms a pourable glaze.
Step 10: Finish and Serve
Drizzle the glaze over the cooled chia seed lemon cake. Let it set before slicing. Enjoy your high-protein, lemony treat any time of day.

Option 1: Using Collagen Powder
Collagen is a flavorless, heat-stable protein that mixes easily into batter. It dissolves without changing texture or taste, making it a great choice for those who want a subtle protein boost. Simply add two to three tablespoons to your dry ingredients when preparing your chia seed lemon cake.
Option 2: Using Whey or Vegan Protein Powder
Whey and plant-based protein powders work well but tend to absorb more liquid. Choose vanilla flavor for best results and reduce the flour slightly or add an extra tablespoon of yogurt to balance moisture. This keeps the chia seed lemon cake soft and prevents it from becoming dry.
Option 3: Using Greek Yogurt
Greek yogurt naturally boosts protein while keeping the cake extra moist. It blends smoothly and adds a light tang that pairs well with lemon. This is already built into the base recipe for the chia seed lemon cake.
Option 4: Using Blended Cottage Cheese
Blended cottage cheese gives the cake a creamy texture and a high-protein profile using whole food ingredients. Blend until smooth before adding to the wet mixture. It’s a smart choice for those avoiding powders and wanting real food in their chia seed lemon cake.
Pro-Tips for a Flawless Cake
- Avoid Overmixing the Batter
Overmixing can make your chia seed lemon cake dense and heavy. Mix just until everything is combined to keep the texture light and fluffy. - Use Room Temperature Ingredients
Cold eggs or yogurt can make the batter curdle or mix unevenly. Let them sit out for about 20 minutes before using to help the batter come together smoothly. - Measure Flour Properly
Spoon flour into your measuring cup and level it with a knife. Scooping directly from the bag packs in too much and can dry out your chia seed lemon cake. - Let the Chia Seeds Soak
Allowing chia seeds to sit in the yogurt and lemon juice gives them time to swell. This improves the cake’s texture and helps bind everything without needing extra eggs. - Test with a Toothpick
To know when the cake is done, insert a toothpick into the center. If it comes out clean, your chia seed lemon cake is ready to cool.
Variations and Toppings
Lemon Blueberry Version
Add a burst of fruity flavor by gently folding in one cup of fresh or frozen blueberries just before pouring the batter into the pan. The berries pair perfectly with the lemon and chia for a refreshing twist on your chia seed lemon cake.
Healthy Lemon Glaze
For a lighter topping, mix plain Greek yogurt with a powdered sugar substitute and a bit of lemon juice. This creates a creamy glaze that complements the tartness of the cake while boosting the protein.
Add Crunchy Toppings
Before baking, sprinkle the top of your batter with sliced almonds or unsweetened coconut flakes. These toppings add a crisp finish and a nice contrast to the soft texture of the chia seed lemon cake.
How to Store and Freeze Your Protein Cake
Storing at Room Temperature
Keep your chia seed lemon cake covered in an airtight container on the counter for up to three days. Make sure it’s fully cooled before storing to prevent moisture buildup.
Refrigerating for Longer Freshness
If you want to extend its shelf life, place the cake in the refrigerator. Wrap it tightly with plastic wrap or store it in a sealed container. It will stay fresh for up to one week while maintaining its flavor and texture.
Freezing for Meal Prep or Future Use
Slice the chia seed lemon cake and wrap individual pieces in parchment paper. Store the slices in a freezer-safe bag or container. You can freeze them for up to two months. To enjoy, let a slice thaw at room temperature or microwave it for about 20 seconds.
