Instructions

1. Prepare the Oven and Pan

Preheat your oven to 350°F (175°C).

Grease and line a 9-inch round cake pan or springform pan with parchment paper.

2. Mix the Dry Ingredients

In a medium bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt

Set aside.

3. Cream Butter and Sugar

In a large mixing bowl, beat the softened butter and sugar for about 3 to 4 minutes until light and fluffy.

This step helps create a tender crumb and airy texture.

4. Add Eggs and Flavorings

Add eggs one at a time, mixing well after each addition.

Stir in:

• Lemon zest
• Lemon juice
• Vanilla extract

The mixture may look slightly curdled, which is completely normal.

5. Combine Wet and Dry Ingredients

Add half the dry ingredients.

Mix gently.

Add the sour cream and mix until incorporated.

Add the remaining dry ingredients and mix just until combined.

Avoid overmixing.

6. Prepare the Raspberries

Toss raspberries with 1 tablespoon flour.

This helps prevent them from sinking during baking.

7. Fold in the Berries

Carefully fold the raspberries into the batter using a spatula.

Work gently to avoid crushing the fruit.

8. Bake

Transfer the batter to the prepared pan.

Smooth the top evenly.

Bake for 45 to 50 minutes or until a toothpick inserted into the center comes out clean.

9. Cool Completely

Allow the cake to cool in the pan for 15 minutes.

Transfer to a wire rack and cool completely before glazing.

10. Make the Lemon Glaze

Whisk together:

• Powdered sugar
• Lemon juice
• Lemon zest

Until smooth and pourable.

11. Finish the Cake

Drizzle the glaze generously over the cooled cake.

Decorate with fresh raspberries and lemon slices if desired.

Slice and serve.

Pro Tips

Use Room Temperature Ingredients

Butter, eggs, and sour cream blend more evenly and create a smoother batter.

Zest Before Juicing

It’s much easier to zest lemons before cutting and squeezing them.

Don’t Overmix

Overmixing develops excess gluten, leading to a tougher cake.

Coat the Berries

A light flour coating helps distribute raspberries evenly throughout the cake.

Cool Before Glazing

Applying glaze to a warm cake causes it to melt and disappear into the crumb.

Use Fresh Lemons

Fresh lemon juice provides significantly brighter flavor than bottled alternatives.

Cultural Context or Fun Facts

Lemon desserts have been popular for centuries thanks to the fruit’s refreshing flavor and natural acidity. Citrus fruits became especially treasured in Europe as trade routes expanded, and lemons eventually found their way into countless baked goods.

Raspberries, meanwhile, have been cultivated since ancient times and were highly valued for both their flavor and vibrant color. Combining lemons and raspberries creates one of baking’s most beloved flavor pairings because the tartness of both ingredients balances sweetness beautifully.

Picnic cakes gained popularity because they travel well, hold their shape without refrigeration for short periods, and can be enjoyed casually outdoors. This recipe embraces that tradition while adding modern flavor and presentation.

What can I substitute for sour cream?

Plain Greek yogurt works very well and maintains a moist texture.

Can I make cupcakes instead?

Yes. Fill cupcake liners about two-thirds full and bake for 18 to 22 minutes.

How do I know when the cake is done?

Insert a toothpick into the center. It should come out clean or with a few moist crumbs.

Can I reduce the sugar?

You can reduce the sugar by about ¼ cup without significantly affecting texture.
