This homemade caramel frappe recipe transforms your kitchen into a gourmet coffee shop in just 5 minutes. I've perfected this creamy, indulgent beverage after countless summer afternoons experimenting with coffee-to-caramel ratios, and now it's become my signature treat when friends visit.
I originally created this recipe during a heatwave when I desperately wanted my caffeine fix without the warmth. Now it's become our Sunday afternoon tradition, with my teenagers requesting it before their study sessions.
Ingredients
- 2 cups strong coffee, chilled: The stronger the coffee, the more authentic the coffee shop taste will be. I recommend brewing double-strength.
- 2 cups whole milk: Creates the creamiest texture; the fat content makes all the difference.
- ⅓ cup caramel syrup: Store-bought works perfectly, but homemade elevates it to another level.
- 4 cups ice: Use fresh ice cubes for the cleanest flavor. Older ice can absorb freezer odors.
- 1 teaspoon granulated sugar: Acts as a flavor enhancer more than a sweetener. Fine sugar dissolves better.
- Whipped cream (optional): Fresh whipped cream is incredible, but canned saves time and still delights.
Step-by-Step Instructions
- Prepare Your Coffee:
- Brew coffee at double strength and refrigerate until completely cold. This prevents the ice from melting too quickly and diluting your frappe. I often make a batch the night before for morning frappes.
- Master the Blending:
- Place all ingredients in your blender with ice at the bottom for better blade contact. Pulse a few times to break down the ice before blending on high for 30-45 seconds. The texture should be smooth but thick enough to hold a straw upright.
- Perfect Your Presentation:
- Pour immediately into tall glasses. The frappe will separate quickly, so serve right after blending. If making for guests, chill the glasses in the freezer for 10 minutes beforehand for that professional touch.
- Add Finishing Touches:
- Top with a generous swirl of whipped cream and an extra drizzle of caramel. For special occasions, I add a sprinkle of sea salt to create a salted caramel variation that's absolutely divine.

The caramel syrup is truly the star ingredient here. After trying numerous brands, I found that the slightly bitter notes in a quality caramel syrup perfectly balance the sweetness and complement the coffee. My daughter now requests this instead of birthday cake every year, served in her special glass mug with extra whipped cream.
Make Ahead Options
You can prepare the coffee component up to three days in advance. I often make a large batch of strong coffee at the beginning of the week and store it in the refrigerator specifically for frappes. This cuts your prep time down to just two minutes when a craving hits.
Dietary Variations
This recipe works beautifully with dairy alternatives. Oat milk creates the creamiest non-dairy version, while almond milk offers a lighter option with a subtle nutty flavor that complements the caramel. For a vegan version, use plant-based milk and top with coconut whipped cream.
Cold Brew Alternative
For an even smoother, less acidic frappe, substitute the chilled coffee with cold brew concentrate. Use 1 cup cold brew concentrate mixed with 1 cup of cold water. Cold brew creates a naturally sweeter base, which means you might want to reduce the added sugar slightly. I discovered this variation during a summer experiment and now prefer it during warmer months.
Temperature Tips
The temperature of your ingredients significantly impacts the final texture. For the perfect consistency, ensure your coffee is refrigerator-cold and your milk is straight from the fridge. If your kitchen is particularly warm, briefly chill your blender jar before making the frappe. This prevents premature melting and maintains that thick, frosty consistency that makes a frappe so satisfying.
