Butterscotch Sauce
- 1/4 cup (4 Tbsp; 56g) unsalted butter
- 3/4 cup (150g) packed light or dark brown sugar
- 3/4 cup (180ml) heavy cream
- 2 teaspoons pure vanilla extract
- 1/2 teaspoon salt
Brown Sugar Cupcakes
- 1 and 2/3 cup (209g) all-purpose flour (spooned & leveled)
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup (200g) packed light or dark brown sugar
- 1/2 cup (8 Tbsp; 113g) unsalted butter, melted
- 1 large egg, at room temperature
- 1/4 cup (60g) yogurt*
- 3/4 cup (180ml) milk*
- 1 Tablespoon (15ml) pure vanilla extract
Vanilla Frosting
- 1 cup (16 Tbsp; 226g) unsalted butter, softened to room temperature
- 3–4 cups (360-480g) confectioners’ sugar
- 1/4 cup (60ml) heavy cream*
- 2 and 1/2 teaspoons pure vanilla extract
- salt, to taste
Instructions
- Make the butterscotch sauce: In a medium saucepan over medium heat, melt the butter. Whisk in the brown sugar, then whisk in cream then let mixture bubble and thicken for 5 minutes without stirring. Remove from heat and whisk in vanilla and salt. Allow to cool.
- Preheat oven to 350°F (177°C). Line 12-count cupcake pan with liners or spray with nonstick spray. Set aside.
- Make the cupcakes: Whisk the flour, baking powder, baking soda, and salt together in a medium bowl. Set aside. In a large microwave-safe bowl, melt butter in the microwave. Whisk in the brown sugar vigorously until no lumps remain. Whisk in egg, yogurt, milk, and vanilla extract until combined. Slowly mix in dry ingredients until no lumps remain. Batter will be thick. Divide batter between 12 cupcake liners. Bake for 20 minutes or until a toothpick inserted in the center comes out clean. Allow to cool completely before filling.
- Make the frosting: In a medium bowl, beat softened butter on medium speed with an electric or stand mixer fitted with a paddle attachment. Beat for 3 minutes until smooth and creamy. Add confectioners’ sugar, cream, and vanilla extract with the mixer running. Increase to high speed and beat for 3 minutes. Add more confectioners’ sugar if frosting is too thin or more cream if frosting is too thick. Beat in a pinch of salt, taste, then beat in another pinch if desired.
- Fill & frost the cupcakes: Fill a plastic squeeze bottle or piping bag (with a filling tip) with butterscotch sauce and push tip of bottle into top of each cupcake, applying enough pressure to fill each cupcake with sauce. Top with vanilla frosting and drizzle with remaining butterscotch sauce. I used a Wilton 1M tip for my frosting.
- Cupcakes remain fresh covered at room temperature for 2 days or in the refrigerator for 4 days. Store any leftover butterscotch in the refrigerator for up to 1 week. I recommend a cupcake carrier for storing and transporting decorated cupcakes.

- Yogurt: Sour cream OR nonfat, low fat, vanilla, plain, Greek or regular yogurt is OK.
- Milk: Skim milk, 1%, 2%, whole, almond milk, soy milk, coconut milk, or rice milk is OK.
- Heavy Cream: Heavy cream preferred in frosting for optimal texture. Milk or half-and-half are acceptable substitutes, but your frosting won’t be as creamy or fluffy.
