What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any fuss. Most are pantry staples, and the gold dust is an optional but dazzling finishing touch.

• For the Cake Batter:
• All-purpose flour – 2 ½ cups (312g), sifted
• Baking powder – 2 ½ teaspoons (10g)
• Salt – ½ teaspoon (3g)
• Unsalted butter – 1 cup (227g), softened (I recommend using Kerrygold for a rich texture)
• Granulated sugar – 1 ¾ cups (350g)
• Large eggs – 4, room temperature
• Whole milk – 1 cup (240ml), room temperature (use unsweetened almond milk for a dairy-free twist)
• Pure vanilla bean paste – 2 teaspoons (for that intense vanilla flavor; vanilla extract works too but a little less punchy)
• For the Vanilla Buttercream Frosting:
• Unsalted butter – 1 cup (227g), softened
• Powdered sugar – 4 cups (480g), sifted
• Heavy cream – 3 tablespoons (45ml) (or coconut cream for dairy-free)
• Pure vanilla bean paste – 1 ½ teaspoons
• Salt – a pinch
• For Decoration:
• Edible gold dust – 1 teaspoon (optional but highly recommended for that signature Leo sparkle)
• Gold leaf flakes (optional, for an extra luxe touch)

Feel free to swap the all-purpose flour with a gluten-free blend if needed. I usually find Bob’s Red Mill Gluten-Free Flour works well here without sacrificing texture. For the gold dust, I love the quality from Chef’s Choice—it sticks well and isn’t overpowering.

Equipment Needed

• Two 8-inch (20cm) round cake pans – non-stick or lined with parchment paper
• Electric hand mixer or stand mixer – for smooth, fluffy batter and frosting
• Mixing bowls – medium and large sizes
• Measuring cups and spoons – for precise measurements (I’m partial to stainless steel sets for accuracy)
• Rubber spatula – to fold ingredients gently
• Cooling racks – to cool the cakes evenly
• Offset spatula or butter knife – to frost the cake smoothly
• Small soft brush – perfect for applying the gold dust evenly

If you don’t have cake pans, you can use a 9×13-inch (23×33 cm) pan, but the baking time will need adjustment. I once used silicone pans for this recipe, and while the cake released nicely, the edges browned a little faster, so keep an eye on it.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your two 8-inch round pans with butter and lightly dust with flour or use parchment paper for easy release. This usually takes about 10 minutes.
2. Mix dry ingredients. In a medium bowl, sift together the flour, baking powder, and salt. Set aside. This prevents lumps and ensures even rising.
3. Cream butter and sugar. In a large mixing bowl, beat the softened unsalted butter and granulated sugar on medium speed until pale and fluffy, about 3-4 minutes. You’ll know it’s ready when the mixture looks lighter and smells sweetly buttery.
4. Add eggs one at a time. Crack the eggs in one by one, beating well after each addition. If the batter looks like it might curdle, don’t panic—keep mixing, and it will come together.
5. Blend in vanilla bean paste. Stir in the vanilla bean paste until evenly distributed. The vanilla flecks add a lovely visual and flavor punch.
6. Alternate adding dry ingredients and milk. With the mixer on low speed, add the dry ingredients in three parts, alternating with the milk in two parts, beginning and ending with the dry ingredients. Mix until just combined—overmixing can make the cake tough.
7. Divide batter evenly. Pour the batter into the prepared pans, smoothing the tops with a spatula. Tap the pans gently on the counter to release air bubbles. This step helps avoid uneven holes in the cake crumb.
8. Bake for 30-35 minutes. The cake is ready when a toothpick inserted in the center comes out clean or with a few moist crumbs. I usually start checking at 28 minutes since ovens vary.
9. Cool in pans for 10 minutes. Then turn cakes out onto cooling racks to cool completely before frosting. This prevents the buttercream from melting.
10. Make the vanilla buttercream. Beat softened butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar, one cup at a time, beating on low until combined. Add heavy cream, vanilla bean paste, and a pinch of salt. Beat on high speed for 3-4 minutes until fluffy and spreadable. If it’s too thick, add a little more cream; if too thin, add a bit more powdered sugar.
11. Assemble the cake. Level the tops with a serrated knife if needed. Spread a thick layer of buttercream on the first cake layer, then place the second on top. Cover the entire cake with a thin crumb coat and chill for 15 minutes.
12. Finish frosting and decorate. Apply a final coat of buttercream for a smooth finish. Using a soft brush, lightly dust the cake with edible gold dust. Add gold leaf flakes for extra shimmer if you like. Remember, less is more with the gold dust—it should look like a gentle glow, not overwhelming.

Cooking Tips & Techniques

• Room Temperature Ingredients: I can’t stress this enough—eggs, milk, and butter should all be at room temperature. This helps the batter mix evenly and results in a tender crumb.
• Don’t Overmix: Overworking the batter develops gluten, making the cake dense. Mix just until the ingredients come together.
• Use Real Vanilla Bean Paste: It gives a richer flavor and those pretty vanilla specks. I tried using only extract once, and it just wasn’t the same.
• Chill Between Frosting Layers: The crumb coat chills help lock in crumbs, so your final frosting looks clean.
• Gold Dust Application: Use a dry, soft brush, and apply sparingly. If you get too heavy-handed, it can look powdery rather than luminous.
• Multitasking: While the cake bakes, start whipping the buttercream. It saves time and keeps your kitchen workflow smooth.
• Common Mistakes: Forgetting to level cake layers can make the final cake look lopsided. Use a serrated knife or cake leveler for even layers.

Variations & Adaptations

• Chocolate Twist: Swap ½ cup (60g) of flour with unsweetened cocoa powder for a chocolate version. Add ¼ cup (60ml) milk extra to keep the batter moist.
• Gluten-Free Option: Use a 1-to-1 gluten-free flour blend. I recommend letting the batter rest for 10 minutes before baking to hydrate the flours.
• Dairy-Free: Replace butter with vegan butter and use coconut or almond milk. Use dairy-free cream for the frosting.
• Seasonal Flavors: Add 1 teaspoon ground cinnamon or a splash of orange zest to the batter for a seasonal touch that pairs beautifully with the gold dust.
• Personal Favorite: I once added toasted chopped pecans between the layers for crunch—it was a hit at a family brunch.

Serving & Storage Suggestions

This cake is best served at room temperature so the vanilla buttercream is soft and luscious. I like to slice it up and serve alongside a cup of strong coffee or a cold glass of milk. For a Leo birthday party, it pairs beautifully with sparkling rosé or a lightly fruity iced tea.

Store leftover cake covered in an airtight container in the fridge for up to 4 days. Before serving again, let it sit at room temperature for about 30 minutes to soften the frosting. You can also freeze the unfrosted cake layers wrapped tightly for up to 2 months. Thaw overnight in the fridge and bring to room temp before frosting.

Flavors actually deepen after a day or two in the fridge, so if you can wait, it tastes even better the next day. Just keep that gold dust touch fresh by applying it right before serving.
