Ingredients You’ll Need

Each ingredient in this Decadent French Butter Cake Recipe works in harmony to create that rich, tender texture and subtle sweetness that makes this cake so memorable. Here are a few tips to make sure you get the best results.

• Unsalted butter: Using unsalted butter lets you control the saltiness perfectly. Make sure it’s softened to room temperature for smooth mixing.
• Granulated sugar: Divided in the recipe, it adds sweetness and helps create that slight crunch on top when sprinkled before baking.
• Large eggs: Room temperature eggs blend more evenly, helping your cake rise beautifully.
• Vanilla extract: A good quality vanilla makes a noticeable difference here—it lifts the flavors without overpowering.
• Cake flour: This lighter flour keeps the cake tender and crumbly instead of dense.
• Baking powder: Essential for a nice lift and light texture.
• Salt: Just a pinch enhances the flavors and balances sweetness.
• Sour cream: Adds moisture and a subtle tang that cuts through the richness beautifully.
• Whole milk: Use it to loosen the batter slightly, making sure the cake stays soft and moist.
• Granulated sugar for topping: Sprinkled generously before baking to give you that irresistible buttery crunch on top.
• Powdered sugar (optional): For dusting after baking to add a touch of elegance.
• Fresh berries (optional): They add freshness and a pop of color that pairs wonderfully with the cake’s richness.

Variations

While I adore the original Decadent French Butter Cake Recipe just as it is, I’ve played around with a few tweaks that add a bit of personal flair—feel free to make it your own!

• Lemon zest: Adding a teaspoon of lemon zest gives the cake a bright, fresh twist that balances the buttery richness. I tried this on a sunny spring afternoon and it was a hit!
• Almond extract: Swapping half the vanilla for almond extract creates a lovely nutty note, which feels especially comforting in the cooler months.
• Dairy-free option: Use dairy-free sour cream and a non-dairy milk substitute if you’re avoiding dairy—just keep an eye on the batter consistency.
• Fruit-filled: Toss in fresh blueberries or raspberries right before baking for a juicy surprise inside. I love this version when berries are in season.
• Gluten-free: Substituting cake flour for a gluten-free baking mix works well, but I recommend adding a little xanthan gum for that perfect crumb.

How to Make Decadent French Butter Cake Recipe

Step 1: Cream the butter and sugar until fluffy

Start by beating the softened unsalted butter with about 1 cup of the granulated sugar until it’s light and fluffy—this usually takes 3 to 5 minutes with an electric mixer. This step is crucial because it traps air and gives your cake its tender crumb. Don’t rush; you want that pale, creamy texture before moving on.

Step 2: Add eggs and vanilla one at a time

Next, add the eggs one by one, mixing well after each addition so they incorporate fully. Then stir in the vanilla extract. If your eggs are room temperature, they’ll blend easier and help the batter stay smooth without curdling.

Step 3: Mix dry ingredients and combine

In another bowl, whisk together the cake flour, baking powder, and salt. Then, alternate adding the dry ingredients and the sour cream (with the whole milk) to the butter mixture. Start and finish with dry ingredients, mixing gently just until combined to avoid overworking your batter.

Step 4: Bake with a sugar topping for crunch

Pour the batter into a buttered cake pan and smooth the top. Sprinkle the remaining 2 tablespoons of granulated sugar evenly over the surface—this creates a lovely golden, crunchy crust as it bakes. Bake in your preheated oven until a toothpick inserted in the center comes out clean, usually around 40-45 minutes. Make sure not to overbake to keep it moist!

How to Serve Decadent French Butter Cake Recipe

Garnishes

I usually dust the top lightly with powdered sugar for a simple, elegant finish. Fresh berries like raspberries or strawberries add a fresh, slightly tart contrast that complements the buttery sweetness. Sometimes, a dollop of whipped cream makes it feel extra special when sharing with guests.

Side Dishes

This cake pairs beautifully with a hot cup of tea or coffee for an afternoon pick-me-up. For brunch, I love serving it alongside fresh fruit salads or a light citrusy sorbet to balance the richness. It’s been my go-to for casual gatherings and also for treats after a savory dinner.

Creative Ways to Present

For birthdays, I’ve decorated this cake with edible flowers and fresh sliced strawberries on top—instantly festive and elegant. Another favorite is serving individual slices with a drizzle of warm berry compote or a scoop of vanilla ice cream, which makes it feel like a true dessert experience.

Make Ahead and Storage

Storing Leftovers

After baking, I usually let the cake cool completely and then store any leftovers in an airtight container at room temperature for up to 2 days. It stays wonderfully moist and flavorful, but be sure to keep it covered to prevent drying out.

Freezing

I’ve had great luck freezing slices wrapped tightly in plastic wrap and then foil—just thaw them overnight in the fridge. The texture holds up well, so you don’t feel like you’re missing out on any of that buttery goodness when you pull a piece out later.

Reheating

To revive leftover cake, I pop a slice in the microwave for about 15 seconds or warm it gently in a low oven wrapped in foil. It softens up perfectly and tastes almost freshly baked—just be careful not to overheat and dry it out!
