The Role of Each Ingredient
Every ingredient plays a specific role in these cupcakes. The flour provides the necessary structure so the cupcakes hold their shape without becoming dense. Butter enriches the batter, and when creamed with sugar, it traps air that makes the cupcakes light and fluffy. Sugar isn’t just for sweetness—it also helps incorporate air into the batter, contributing to the airy texture. The levain makes the batter more pliable and adds a subtle depth of flavor, while vanilla enhances all the flavors and delicately perfumes the cupcakes.
Why Creaming Butter and Sugar Matters
Creaming the butter and sugar is a key step for perfectly light cupcakes. Beating these two ingredients together for 2–3 minutes incorporates air into the batter, allowing the cupcakes to rise and stay tender. Skipping this step, or not beating long enough, can result in slightly denser cupcakes.

The Importance of Room Temperature Eggs
Using room temperature eggs makes a noticeable difference. Cold eggs can harden the butter when added, causing lumps in the batter and preventing the cupcakes from rising properly. Room temperature eggs mix smoothly, ensuring a uniform batter and evenly tender cupcakes.

Tips for Perfect Salted Caramel Cupcakes
A few tips to ensure success: always sift your dry ingredients to prevent lumps and create a better texture. Don’t overmix the batter once the flour is added; mix just enough to incorporate everything. For the frosting, beat the butter until light and creamy before adding sugar, cream, and caramel—this guarantees a light and airy frosting. To create the marbled effect, add the extra caramel on top and swirl with a toothpick or spatula, without overmixing, to preserve the visual appeal.

With these small touches, every cupcake becomes a true delight: fluffy, fragrant, and topped with a perfectly balanced creamy salted caramel frosting. Even beginners can achieve impressive results, and the aroma that fills the kitchen while baking instantly sets the scene for indulgence.

Ingredients
For the cupcakes
140 g all-purpose flour
8 g (2 tsp) baking powder
4 g (½ tsp) salt
110 g unsalted butter
200 g sugar
10 g (1 tbsp) vanilla extract
2 large eggs, room temperature
100 g active sourdough starter
140 g whole milk
For the marbled caramel frosting
200 g unsalted butter, softened
400 g powdered sugar
5 g vanilla paste or extract
30 g caramel
30 g cream
60 g extra caramel for marbling
For the cupcakes
1 cup all-purpose flour
2 tsp baking powder
½ tsp salt
½ cup unsalted butter
1 cup sugar
1 tbsp vanilla extract
2 large eggs, room temperature
½ cup active sourdough starter
½ cup whole milk
For the marbled caramel frosting
¾ cup unsalted butter, softened
3 ¼ cups powdered sugar
1 tsp vanilla paste or extract
2 tbsp caramel
2 tbsp cream
4 tbsp extra caramel for marbling
Steps
1
Preheat the oven to 350 °F (177 °C) and line a 12-cup muffin pan with cupcake liners (or use mini liners for 48 mini cupcakes).
2
In a large bowl, sift together the flour, baking powder, and salt. Set aside.
3
In another bowl, beat the butter and sugar on high speed for 2–3 minutes until the mixture becomes lighter, creamy, and fluffy. Add the eggs, levain, and vanilla, and mix well. Then add the milk. The batter may look slightly grainy or lumpy—that’s completely normal. At low speed, add the flour mixture, mixing just enough to combine to keep the cupcakes tender.
4
Divide the batter into cupcake liners, filling each about 2/3 full. Bake in the preheated oven at 177 °C (350 °F) for about 15 minutes for mini cupcakes or up to 20 minutes for large ones, until a toothpick inserted in the center comes out clean and the tops are golden. Let cool completely before frosting.
5
For the frosting, in a large bowl, beat the softened butter at medium-high speed for 2–3 minutes until light and airy. Add powdered sugar, vanilla, caramel, and cream, and beat about 30 seconds just to combine, without overmixing.
To create the marbled effect, drop the extra 60 g of caramel in small spots over the frosting and swirl with a spatula or toothpick, without fully mixing to keep the marbled look.
6
Frost the cooled cupcakes using a piping bag or spatula. For an extra indulgent look, drizzle a few strands of caramel on top.
Store cupcakes 2–3 days at room temperature in an airtight container, or refrigerate if the frosting is very creamy. For even more flavor, use a well-fed, active sourdough starter.
