Ingredients
- All Purpose Flour: Plain, simple all purpose flour that you measure properly using a kitchen scale or the spoon-and-level method will create moist and fluffy cupcakes.
- Baking Powder & Baking Soda: Together, both of these leavening agents contribute to rise and the gorgeous cupcake domes.
- Salt: Salt brings out sweetness.
- Unsalted Butter: Melted unsalted butter adds flavor and moisture to every bite.
- Dark Brown Sugar: Dark brown sugar creates a deeper, nuttier flavor that mimics caramel.
- Egg: A large egg at room temperature adds structure to the cupcakes.
- Vanilla Extract: Vanilla rounds out the flavor and completes the cupcakes.
- Buttermilk: Room temperature buttermilk creates a moist, light, and tender cupcake.
Step by Step Process
STEP 1: Start by preheating your oven to 350 degrees Fahrenheit. Then, line a 12-count muffin pan with liners.


STEP 2: In a medium bowl, whisk all purpose flour, baking powder, baking soda, and salt together until combined. Set aside.
STEP 3: In a large bowl, whisk melted butter, dark brown sugar, a room temperature egg, vanilla extract, and room temperature buttermilk together until smooth.


STEP 4: Then, add the dry ingredients to the bowl of wet ingredients. Mix only until you see the dry ingredients disappear. Mixing past once the dry pieces have incorporated could lead to dry, dense cupcakes.
STEP 5: Transfer the batter between the liners, adding about ¼ cup of batter to each liner. Bake the cupcakes for 17-21 minutes or until the tops are light golden brown, domed, and a toothpick inserted into the center comes out with moist crumbs. Allow the cupcakes to cool before decorating.
Frosting and Decoration


STEP 1: In a large bowl with a hand mixer or in the bowl of a stand mixer fitted with a paddle attachment, beat room temperature butter, powdered sugar, and cocoa powder on low speed until smooth. This should be about 2-3 minutes of mixing.
STEP 2: Pour heavy cream into the frosting and beat on high speed for at least 3 minutes to create a light frosting. Transfer the frosting to a piping bag fitted with your desired tip or a zippable plastic bag with the corner snipped off for greater control when frosting.


STEP 3: Next, use a knife to cut out a portion of the center of each cupcake or use a spoon to dig and create a well. Add about ½ tablespoon-1 tablespoon of caramel sauce to the center of each cupcake.
STEP 4: Then, frost each cupcake as desired. Immediately, top the cupcakes with a piece of shortbread and drizzle additional caramel on top.

Frequently Asked Questions
These cupcakes pay homage to millionaire's- a classic treat with a shortbread, chewy caramel, and rich chocolate topping!
Sour cream and buttermilk work together to add moisture and a more tender texture. To ensure the moistest cupcakes possible, make sure to measure your flour properly by using a kitchen scale or by spooning and leveling flour into your measuring cups.

Expert Tips
Room Temperature Ingredients: For moist and fluffy cupcakes, make sure to use a room temperature egg and room temperature buttermilk in the batter.
Measuring Flour: To avoid dry and dense cupcakes, measure flour properly by using a kitchen scale. Measure out 175g exactly or use a spoon to transfer flour from your container to measuring cups before taking a knife to level off the top.
Creating the Well: To create a space for the filling, use a ½ teaspoon measuring tool to carve out the center of the cupcake. Do not carve too deep that you open up the bottom of the cupcake. However, you’ll get a better visual effect if you carve deeper rather than wider.
Thick Caramel: Do not use a thin caramel sauce when filling the cupcakes. If you do, the cupcake will absorb it rather than creating a thick filling effect.

- ½ teaspoon (6g) salt
- ½ cup (110g) unsalted butter, melted
- ½ cup (115g) dark brown sugar, packed

- ⅔ cup buttermilk (132g), room temperature
For the Fudge Buttercream
- 1 cup (220g) unsalted butter, room temperature
- ½ cup (54g) unsweetened dark chocolate cocoa powder
- 2 cups (240g) powdered sugar
- ⅓ cup (80g) heavy cream
Instructions
For the Caramel Cupcakes
- Preheat your oven to 350 degrees Fahrenheit and line a 12-count muffin pan with liners.
