👩🍳 Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease an 8-inch square baking pan or line it with parchment paper if desired.
Since this is a one-pan cake, you’ll mix everything directly inside the pan.
Step 2: Mix the Dry Ingredients
Add to the pan:
Flour
Sugar
Baking soda
Salt
Whisk thoroughly until everything is evenly combined.
Step 3: Create the Wells
Using the back of a spoon, create three small wells in the dry mixture.
Pour into the wells:
Vanilla
Vinegar
Vegetable oil
Pour the water over everything.
Add:
Lemon juice
Lemon zest
Step 4: Stir the Batter
Using a fork or small whisk, stir gently until no dry flour remains.
Avoid overmixing.
The batter should become smooth with only a few tiny lumps.
Step 5: Prepare the Blueberries
Toss the blueberries with one teaspoon of flour.
This simple trick helps prevent them from sinking to the bottom during baking.
Fold them gently into the batter.
Step 6: Bake
Place the pan into the preheated oven.
Bake for 35–40 minutes, or until:
The top is lightly golden.
The cake springs back when touched.
A toothpick inserted into the center comes out clean or with only a few moist crumbs.
Step 7: Cool
Allow the cake to cool in the pan for about 15 minutes.
Transfer it to a cooling rack and let it cool completely before glazing.
🍋 Make the Lemon Glaze
Whisk together:
Powdered sugar
Fresh lemon juice
Mix until smooth and pourable.
Drizzle generously over the cooled cake.
Finish with extra lemon zest for a beautiful burst of color and fresh citrus aroma.
🫐 Tips for Success
Fresh lemon zest provides the brightest flavor, so zest the lemon before juicing it. Tossing the blueberries in flour keeps them suspended throughout the cake instead of sinking. If using frozen blueberries, don’t thaw them first—add them straight from the freezer and gently fold them into the batter to minimize color bleeding. Mix just until combined to keep the crumb light and tender. Always let the cake cool completely before adding the glaze so it sets beautifully instead of soaking in.
🍋 Flavor Variations
This recipe is wonderfully versatile. Add a teaspoon of poppy seeds for a bakery-style lemon poppy seed cake, or mix in shredded coconut for extra texture. A handful of chopped almonds or walnuts adds crunch, while a pinch of ground ginger or cardamom brings a warm, aromatic twist. You can also swap the blueberries for raspberries, blackberries, or diced strawberries depending on what’s in season.
🍽 Serving Suggestions
Serve this cake slightly chilled or at room temperature with a cup of tea or freshly brewed coffee. It’s equally delicious as a light afternoon snack, a simple family dessert, or a refreshing summer treat. For a more indulgent presentation, top each slice with dairy-free whipped cream, coconut whipped topping, or a scoop of your favorite plant-based vanilla ice cream. Garnish with fresh blueberries, thin lemon slices, and a sprinkle of lemon zest for an elegant finish.
🧊 Storage
Store the cake in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate it for up to 1 week. The lemon flavor becomes even more pronounced after a day, making leftovers especially delicious. You can also freeze individual slices for up to 3 months. Wrap each slice tightly in plastic wrap and place them in a freezer-safe bag or container. Thaw overnight in the refrigerator or at room temperature before serving.
