How to make Sonic bourbon caramel iced coffee
Sonic Bourbon Caramel Iced Coffee is a flavored iced coffee drink from Sonic Drive-In that combines smooth cold coffee with a bourbon-inspired caramel flavor.
Ingredients
- Cold Brew Coffee (1 ½ cups)
- Bourbon Caramel Syrup (2 tablespoons)
- Homemade Bourbon Caramel Syrup:
- ½ cup sugar
- 2 tablespoons butter
- ¼ cup heavy cream
- 1 teaspoon vanilla extract
- ¼ teaspoon imitation bourbon flavoring (optional)
- Homemade Bourbon Caramel Syrup:
- Milk or Cream (¼ cup)
- Ice
- Whipped Cream
- Caramel Drizzle
- (Optional) Mini Cowboy Hat Garnish
Instructions
- Make the Cold Brew Coffee: If you’re preparing cold brew at home, combine coarse ground coffee and water in a 1:4 ratio. Let it steep in the refrigerator for 12-24 hours. Strain the coffee using a fine mesh sieve or coffee filter. Your homemade cold brew is ready!
- Prepare the Bourbon Caramel Syrup (if making from scratch): Heat the sugar in a saucepan over medium heat, stirring constantly until it melts into a deep amber color.
- Add butter and stir until fully incorporated. Slowly pour in the heavy cream (be careful, as it will bubble up). Reduce heat and let it simmer for 2 minutes.
- Remove from heat and stir in vanilla extract and optional imitation bourbon flavoring. Let it cool completely before using.
- Assemble the Drink: Fill a glass with ice—ideally, nugget ice for that authentic Sonic feel. Pour in the cold brew coffee, followed by the bourbon caramel syrup. Stir gently to combine. Add milk or cream to taste, then stir again for a creamy consistency.
- Add the Toppings: Pipe whipped cream over the coffee using a swirl motion for a polished look. Drizzle caramel sauce on top for added sweetness and a professional finish.
- If you want to mimic Sonic’s playful presentation, add a miniature cowboy hat garnish or other decorative touch for fun!
Tips for the Best Results
- Use Quality Coffee: Choose a good-quality medium or dark roast coffee for your cold brew to ensure rich flavor.
- Adjust Sweetness: Start with 2 tablespoons of bourbon caramel syrup and adjust to your preferred sweetness level.
- Custom Milk Options: Feel free to use dairy-free alternatives like almond milk, oat milk, or coconut milk for a twist.
- Double the Batch: Make extra cold brew and caramel syrup so you can enjoy this drink all week long.
- Chill Your Glass: Pop your glass in the fridge for a few minutes before filling it to keep your iced coffee even colder.
What to serve with
Sonic Bourbon Caramel Iced Coffee is undeniably rich, smooth, and sweet, making it a perfect centrepiece for a coffee break or dessert hour. However, pairing this delectable coffee with complementary treats can elevate your experience even more.
Caramel-Focused Treats
- Caramel Cookies: Soft caramel thumbprint cookies or caramel-dipped biscotti can create a perfectly harmonious match.
- Salted Caramel Brownies: The interplay between salty and sweet flavors mirrors the complexity of your Sonic Bourbon Caramel Iced Coffee, making them a decadent pairing.
- Caramel Popcorn: A crunchy, sweet-salty snack is both playful and additive to the coffee’s caramel tones.
Fall Favorites
- Pumpkin Muffins: The warm spices, like cinnamon and nutmeg, in pumpkin muffins complement the bourbon caramel coffee and create a cozy fall experience.
- Apple Pie or Strudel: Apple and caramel are a trusted flavor combo. Pair this iced coffee with apple-based desserts for a comforting treat.
Chocolate Treats
- Chocolate Croissant: The buttery flakiness of a croissant and the smooth richness of chocolate pair perfectly with the coffee’s sweet syrup.
- Dark Chocolate Bark: Slightly bitter dark chocolate balances the sweetness of the drink for a sophisticated pairing.
Ingredients Substitutes
Recreating Sonic Bourbon Caramel Iced Coffee at home sometimes means working with what you already have in your kitchen or adapting for allergies, dietary preferences, or the lack of specific ingredients.
1. Cold Brew Coffee
Cold brew coffee is the foundation of this drink, offering a smooth and mellow taste. However, if you don’t have cold brew on hand or prefer alternatives, here are some substitutes:
- Iced Coffee: Brew regular coffee and let it cool before serving over ice. While it may not offer the same smoothness as cold brew, it’s an easy substitute.
- Instant Coffee: Combine 1-2 teaspoons of instant coffee granules with cold water and stir until dissolved. This option is quick and convenient, though it won’t deliver the flavor depth of cold brew.
- Espresso and Water: Mix 1 or 2 shots of espresso with cold water to mimic cold brew. This creates a strong coffee base with bold flavor. (Great for adding intensity!)
- Decaf Coffee: Use decaf options for those who prefer to avoid caffeine without compromising the drink’s deliciousness.
2. Bourbon Caramel Syrup
The bourbon caramel syrup is the star flavoring in Sonic’s drink, but there are several ways to replace or replicate it:
Store-Bought Alternatives:
- Regular Caramel Syrup: It’s widely available and works as a solid replacement, though you’ll miss out on the subtle bourbon undertones. Add ½ teaspoon of vanilla extract to give it extra depth.
- Butterscotch Syrup: Similar to caramel but with a richer, buttery taste. It complements the coffee perfectly.
- Honey or Maple Syrup: While not identical to caramel, these syrups add natural sweetness and complexity that pairs nicely with coffee.
DIY Alternatives:
If you’re making your own caramel syrup but lack bourbon flavoring, you can try these substitutes:
- Vanilla Extract: Replace imitation bourbon flavoring with vanilla for a fragrant sweetness.
- Cinnamon: A pinch of ground cinnamon added to homemade caramel can provide a warm, spiced dimension similar to bourbon notes.
- Optional Alcoholic Twist: If you’re okay with alcohol, you can add a splash (a few drops) of real bourbon to your homemade caramel syrup for authenticity. For a non-alcoholic fix, use bourbon-flavored extracts.
3. Milk or Cream
The creaminess of the iced coffee balances the bold coffee and sweet caramel flavors. If you’re out of milk or have specific dietary needs, there are plenty of substitutes:
- Non-Dairy Milk: Almond milk, oat milk, coconut milk, or soy milk work beautifully as alternatives to dairy milk. Oat milk, in particular, creates a creamy texture and natural sweetness.
- Whipped Coconut Cream: For a rich and indulgent substitute, use whipped coconut cream instead of dairy cream in your coffee.
- Half-and-Half or Heavy Cream Alternatives: If you want a richer texture without heavy cream, try evaporated milk or full-fat canned coconut milk.
4. Whipped Cream
Whipped cream is used for topping and presentation. If you’re missing whipped cream or want a healthier or vegan option:
- Non-Dairy Whipped Toppings: Many brands offer plant-based whipped creams made from almond, oat, or coconut milk. These are great substitutes and work just as well for topping.
- DIY Whipped Cream Substitute: Chill full-fat canned coconut milk, scoop out the solid layers, and whip until fluffy. You can also add a sweetener like powdered sugar or vanilla for flavor.
5. Caramel Drizzle for Topping
The caramel drizzle adds beauty and extra sweetness to the drink’s presentation. Here’s how you can substitute or get creative:
- Chocolate Syrup: A rich chocolate drizzle adds a fun variation for chocolate lovers.
- Maple Syrup: Pour maple syrup sparingly over the whipped cream for a warm, sweet twist.
- Honey: A thin drizzle of honey works in a pinch and adds a unique flavor that pairs well with coffee.
6. Ice
Sonic’s nugget ice is iconic for its texture, but you don’t have to rush out to find it. Here are substitutions:
- Crushed Ice: Use a blender to crush regular ice into smaller pieces to mimic nugget ice.
- Regular Ice Cubes: Classic ice cubes work well if nugget ice isn’t available. For an extra cold drink, freeze coffee cubes so your iced coffee doesn’t dilute when the ice melts.
- Reusable Ice Cubes: If you’re concerned about watering down the drink, use reusable food-grade ice cubes or stainless-steel chilling stones.
Final Thoughts
With this recipe, you don’t need a drive-thru to enjoy the indulgent sweetness of Sonic Bourbon Caramel Iced Coffee. Perfect for mornings, afternoons, or whenever your sweet tooth and coffee cravings strike, this homemade version is sure to become a favorite.
