Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 350°F (175°C).

Grease a 9×13 inch baking pan or line it with parchment paper.

This will make it easier to remove the cake after baking.

2. Mix the Dry Ingredients

In a large bowl, combine:

• Flour
• Baking powder
• Baking soda
• Salt

Whisk the ingredients together until evenly mixed.

3. Cream the Butter and Sugar

In another large bowl, beat the softened butter and granulated sugar together.

Mix for about 2–3 minutes until the mixture becomes light and fluffy.

Small tip: Soft butter mixes more easily and creates a softer cake.

4. Add the Eggs

Add the eggs one at a time.

Mix well after each egg until fully combined.

5. Add Lemon and Vanilla

Add the lemon juice, lemon zest, and vanilla extract to the mixture.

Stir until everything is well blended.

6. Combine Wet and Dry Ingredients

Add the dry ingredients to the batter gradually.

Pour in the milk while mixing.

Stir until the batter becomes smooth.

Avoid overmixing so the cake stays soft.

7. Prepare the Blueberries

Place the blueberries in a small bowl and toss them with 1 tablespoon of flour.

This step helps keep them evenly distributed in the cake.

8. Fold in the Blueberries

Gently fold the blueberries into the batter using a spatula.

Be careful not to crush them.

9. Bake the Cake

Pour the batter into the prepared baking pan.

Spread it evenly.

Bake for 30–35 minutes or until a toothpick inserted into the center comes out clean.

10. Cool the Cake

Remove the cake from the oven and allow it to cool for about 20 minutes.

Cooling helps the glaze set better.

11. Prepare the Lemon Glaze

In a small bowl, mix:

• Powdered sugar
• Lemon juice
• Milk

Stir until the glaze becomes smooth.

12. Add the Glaze

Drizzle the glaze over the cooled cake.

Garnish with extra blueberries and lemon zest if desired.

Tips & Variations

Add a crumb topping

A simple crumble topping made with butter, sugar, and flour adds extra texture.

Use frozen blueberries

Frozen berries work well. Do not thaw them before adding to the batter.

Make it gluten-free

Use a gluten-free flour blend for baking.

Make it dairy-free

Use plant-based milk and dairy-free butter.

Add cream cheese frosting

Instead of glaze, you can use a light cream cheese frosting.

Add more lemon flavor

Extra lemon zest gives the cake a stronger citrus taste.

Small tip: Always measure flour carefully to avoid making the cake too dense.
