Step-by-Step Instructions
1. Make the Lemon Cake
- Preheat oven to 350°F and position a rack in the middle.
- In a mixing bowl, rub lemon zest into sugar until fragrant.
- Whisk in flour, baking soda, baking powder, and salt.
- Add butter, yogurt, eggs, and vanilla; mix until just combined, then beat briefly to smooth.
- Toss blackberries with a little flour; fold into batter.
- Pour into a greased and parchment-lined springform pan. Smooth the top.
- Bake 30 minutes, rotate, and bake 20–25 minutes more, until a toothpick comes out clean. Cool completely.
2. Macerate the Blackberries
- In a bowl, combine blackberries, lemon juice, and sugar.
- Let sit at room temp until juicy (or refrigerate overnight).
3. Make Lemon Curd Mascarpone
- Whisk yolks, sugar, salt, zest, and juice in a heatproof bowl.
- Place over simmering water and whisk until thick like mayonnaise.
- Remove from heat; whisk in mascarpone one spoonful at a time until smooth.
- Cover with plastic wrap touching the surface; chill until cold.
4. Make the Whipped Cream
- Set aside a small portion of lemon curd.
- Whip cream to almost stiff peaks.
- Fold cream into remaining curd in two additions until airy and spreadable.
5. Assemble the Cake
- Slice cooled cake into two even layers.
- Place bottom layer on a stand; spread with half the whipped cream.
- Mash half the macerated berries (if fresh) and scatter over cream.
- Top with second cake layer; spread remaining cream on top.
- Spoon swirls of reserved lemon curd; top with remaining berries.
- Chill 1–2 hours for cleaner slices, or serve immediately for a rustic look.

Pro Tips for Success
- Use fresh zest – It’s the quickest way to boost lemon flavor.
- Check your leaveners – Expired baking soda or powder = flat cake.
- Go for frozen berries inside – They break down beautifully in the filling.
- Chill before slicing – An hour in the fridge sets the cream for picture-perfect layers.
- Scale it up – For a 9-inch cake, multiply batter ingredients by 1.5.
Flavor Variations
- Lemon-Blueberry – Swap blackberries for blueberries and add a lavender garnish.
- Raspberry-Lemon – Pair tangy lemon with vibrant raspberries.
- Coconut-Lemon – Add shredded coconut to the filling for a tropical twist.
- Poppyseed-Lemon – Fold a tablespoon of poppyseeds into the batter for texture.
Serving Ideas
- Elegant brunch centerpiece – Slice thin for guests to enjoy alongside tea or coffee.
- Garden party dessert – Garnish with edible flowers and mint sprigs.
- Casual weekend treat – Serve chilled with extra lemon curd drizzled over each slice.
