How to Make the Recipe

Step 1: Prep and Dry Ingredients
Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line it with parchment paper so your cake pops out perfectly. In a medium bowl, whisk together your flour, baking powder, baking soda, and salt.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, beat that softened butter and sugar together for about 3–4 minutes. You want it to look light and fluffy—this airiness is key to a great cake!
Step 3: Add the Aromatics
Beat in your eggs one at a time, making sure each is well incorporated. Then, stir in that fragrant lemon zest and vanilla extract. It’ll smell amazing already!
Step 4: The Alternating Mix
Gradually add your dry ingredients to the butter mixture, alternating with the buttermilk. Start and end with the flour. Mix until just combined—be gentle here so you don’t overwork the batter!
Step 5: Bake to Perfection
Pour the batter into your prepared pan and smooth the top. Bake for 35–40 minutes. You’ll know it’s done when a toothpick comes out clean. Let it cool completely before the grand finale.
Step 6: Master the Raspberry Sauce
While the cake cools, simmer your raspberries, sugar, and lemon juice in a saucepan for 5–7 minutes until they break down. Stir in your cornstarch slurry and cook for another 2–3 minutes until it’s thick and glossy.
Step 7: The Final Flourish
Spoon that gorgeous sauce generously over the cooled cake. Let it drip down the sides for that rustic-chic look, and top with extra fresh berries if you’re feeling fancy!
Pro Tips for Making the Recipe
- Room Temperature Ingredients: Make sure your eggs, butter, and buttermilk are at room temperature. This helps everything emulsify into a smooth, velvety batter.
- Don’t Overmix: Once you add the flour, stop mixing as soon as the streaks disappear. This keeps the cake tender rather than tough.
- The Glossy Sauce: If you prefer a seedless sauce, you can press the cooked raspberry mixture through a fine-mesh sieve before adding the cornstarch slurry.
How to Serve
This cake is a showstopper all on its own, but here are a few ways to level it up:
- With Cream: Serve a slice with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream.
- Brunch Style: It pairs beautifully with a hot cup of Earl Grey tea or a bubbly mimosa.
- Extra Garnish: A light dusting of powdered sugar over the berries adds a lovely touch.

Method
- Preheat oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, cream the softened butter and 1 cup sugar until light and fluffy, about 3-4 minutes.
- Add eggs one at a time, beating well after each addition. Mix in lemon zest and vanilla extract.
- Gradually add the dry ingredients to the butter mixture, alternating with buttermilk, beginning and ending with the flour mixture. Mix until just combined without overworking the batter.
- Pour the batter into the prepared pan and smooth the top. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely.
- While the cake cools, prepare the raspberry sauce. In a saucepan over medium heat, combine raspberries, 1/3 cup sugar, and lemon juice. Cook for 5-7 minutes until berries break down and release their juices.
- Stir in the cornstarch slurry and continue cooking for 2-3 minutes until the sauce thickens to a glossy consistency. Remove from heat and let it cool slightly.
- Spoon the raspberry sauce generously over the cooled cake, allowing it to gently drip down the sides. Garnish with extra fresh raspberries before serving if desired.
Notes
Make Ahead and Storage
Storing Leftovers
You can keep this cake in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days to keep the sauce fresh.
Freezing
The cake (without the sauce) freezes beautifully! Wrap it tightly in plastic wrap and foil for up to 3 months. I recommend making the sauce fresh when you’re ready to serve.
Reheating
If you like a warm slice, pop it in the microwave for 10–15 seconds. It makes the raspberry sauce extra gooey and delicious!
FAQs

1. Can I use frozen raspberries instead of fresh? Absolutely! Frozen raspberries work perfectly for the sauce. You don’t even need to thaw them first; just toss them into the saucepan and they will break down beautifully as they heat up.
2. What if I don’t have buttermilk? No problem! You can make a quick DIY version by adding 1 tablespoon of lemon juice or white vinegar to a cup of regular milk. Let it sit for 5–10 minutes until it curdles slightly, and you’re good to go.
3. Can I make this in a square pan instead of a round one? You sure can. A 9×9 inch square pan will work just fine. Just keep an eye on the bake time, as it might vary by a few minutes depending on the depth of the pan.
4. How do I stop my raspberries from being too tart? If your berries are particularly zingy, feel free to taste the sauce while it’s simmering and add an extra tablespoon of sugar if needed. It’s all about your personal preference!
