Step‑by‑Step Instructions for Lemon Blueberry Olive Oil Cake
Step 1: Roast the Blueberries
Begin by preheating your oven to 400°F (200°C). In a mixing bowl, gently toss fresh blueberries with a drizzle of extra virgin olive oil and pure maple syrup. Spread the coated blueberries onto a parchment-lined baking sheet and roast for 10 to 15 minutes until bubbling and glistening. This step enhances their sweetness, adding a burst of flavor to your Lemon Blueberry Olive Oil Cake.
Step 2: Prepare Your Cake Pans
While the blueberries are roasting, preheat your oven again, this time to 375°F (190°C). Grease two round cake pans with olive oil and line the bottoms with parchment paper for easy removal. The parchment will help ensure that your Lemon Blueberry Olive Oil Cake comes out without sticking, giving you beautifully intact layers to work with later.
Step 3: Make the Buttermilk
To create a dairy-free buttermilk, combine almond milk with fresh lemon juice in a small bowl. Allow this mixture to sit for 5 to 10 minutes until it slightly thickens. This acidic combination will tenderize the batter, giving the cake its desirable moist texture without relying on traditional buttermilk, perfect for your Lemon Blueberry Olive Oil Cake recipe.
Step 4: Mix the Dry Ingredients
In a large mixing bowl, whisk together cake flour, all-purpose flour, baking powder, lemon zest, and sea salt until combined. Sifting these ingredients will incorporate air, contributing to a lighter texture in your cake. Make sure all the dry ingredients are fully integrated for an even rise in your Lemon Blueberry Olive Oil Cake.
Step 5: Cream the Butter and Sugar
In a large bowl, beat softened unsalted butter and organic cane sugar together with an electric mixer until the mixture becomes pale and fluffy, approximately 3-5 minutes. Add the eggs one at a time, mixing well between each addition to ensure thorough incorporation. This creaming process creates a stable base for your Lemon Blueberry Olive Oil Cake.
Step 6: Combine the Ingredients
Gradually add the mixed dry ingredients into the butter-sugar mixture, alternating with the prepared buttermilk. Stir gently just until the batter is smooth, being careful not to over-mix. Finally, fold in the roasted blueberries, ensuring they are evenly dispersed. This careful folding retains the lightness of your batter essential for your Lemon Blueberry Olive Oil Cake.
Step 7: Bake the Cake
Divide the batter equally between the prepared cake pans and smooth the tops. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. You’ll know the cakes are done when they are golden brown and spring back lightly upon touch. Allow them to cool in the pans for 10 minutes before transferring them to wire racks.
Step 8: Prepare the Blueberry Filling
While the cakes are cooling, mix the blueberry preserves with a little lemon juice in a bowl. Stir until smooth and well combined. This fruity filling will add an extra layer of deliciousness to your Lemon Blueberry Olive Oil Cake, providing a delightful contrast with the fluffy layers of cake.
Step 9: Make the Frosting
In a clean mixing bowl, beat unsalted butter until smooth. Gradually add powdered sugar, continuing to mix until creamy. Incorporate a splash of lemon juice and enough milk to reach your desired frosting consistency. This light and tangy frosting will beautifully complement your Lemon Blueberry Olive Oil Cake.
Step 10: Assemble the Cake
Once the cake layers have cooled completely, place one layer on a serving plate. Spread a generous amount of blueberry filling over the top, followed by a layer of frosting. Place the second cake layer on top and frost the exterior of the cake. Chill briefly to set the frosting, allowing the flavors to meld together beautifully in your Lemon Blueberry Olive Oil Cake.

Lemon Blueberry Olive Oil Cake Recipe FAQs
How do I choose the right blueberries for the cake?
Absolutely! When selecting blueberries, look for firm, plump berries with a deep blue color. Avoid any that show signs of mold or have dark spots all over, as this can indicate overripeness. Organic berries are usually sweeter and more flavorful, enhancing your Lemon Blueberry Olive Oil Cake.
What’s the best way to store leftovers?
To keep your Lemon Blueberry Olive Oil Cake fresh, store it in an airtight container in the fridge for up to 4-5 days. This helps retain its moisture. If you notice the cake starting to dry out, simply add a slice of bread inside the container to keep it moist!
Can I freeze this cake?
Yes, you can freeze your Lemon Blueberry Olive Oil Cake! Once completely cooled, wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It will keep well for up to 3 months. When ready to enjoy, thaw it in the fridge overnight for the best texture.
What if my cake turns out dense?
Very good question! A dense cake can often be attributed to over-mixing the batter or using cold ingredients. Ensure all your ingredients are at room temperature before mixing. If using gluten-free flour, measure it properly, as too much can lead to a denser texture. Remember, fold the blueberries in gently after combining the wet and dry ingredients to maintain fluffiness.
Are there any dietary considerations I should keep in mind?
Definitely! This Lemon Blueberry Olive Oil Cake can be adapted to cater to various dietary needs. For gluten-free options, I recommend using Bob’s Red Mill 1-to-1 Baking Flour. For a vegan version, substitute eggs with flax eggs or chia eggs (mix 1 tablespoon of flaxseed meal or chia seeds with 2.5 tablespoons of water, let it sit for 5-10 minutes until it becomes gel-like). Always double-check labels for allergies, especially with ingredients like maple syrup and baking powder!
