The Caramel Krunch Shake is part of KFC’s Kwench specialty drinks line, featuring a creamy caramel milkshake drizzled with caramel sauce and topped with a crunchy speculoos (biscoff-style) crumb. This is a homemade interpretation designed to get close to the original, not KFC’s proprietary recipe.

What makes KFC’s Caramel Krunch Shake special
KFC’s Caramel Krunch Shake stands out for its combination of a thick, creamy vanilla milkshake, rich caramel sauce, and a topping of crunchy speculoos biscuit crumbs. The brand describes it as “a creamy and indulgent caramel milkshake drizzled with a luxurious caramel sauce & topped with a krunchy speculoos crumb.” The signature element is the contrast between the smooth shake and the crispy, spiced biscuit topping. When recreating this at home, it’s important to keep the biscuit crumbs as a topping only—blending them in would lose the crunch that defines the drink. A 4:1 ratio of ice cream to milk helps achieve the dense, spoonable texture KFC serves in store.
Ingredients
- 2 cups vanilla ice cream
- 1/2 cup whole milk
- 3 tablespoons (plus extra for drizzling) caramel sauce
- 2-3 biscuits, crushed speculoos (biscoff-style) biscuits — Buy on Amazon
- to top whipped cream (optional)
Tools you’ll need
- Blender (for smooth blending without over-thinning)
- Tall glass (preferably chilled to help keep the shake thick)
- Measuring cups and spoons
- Wide straw or long spoon
- Small bowl or bag for crushing biscuits
How to make it
- Measure and prep: Gather 2 cups of vanilla ice cream, 1/2 cup of whole milk, and 3 tablespoons of caramel sauce. Crush 2–3 speculoos (biscoff-style) biscuits into coarse crumbs. Chilling your glass beforehand helps keep the shake thick.
- Blend the base: Combine ice cream, milk, and caramel sauce in the blender. Use the 4:1 ice cream-to-milk ratio for a shake that’s thick and creamy. Blend just until smooth—overblending warms and thins the shake, while underblending leaves chunks behind.
- Pour and swirl: Pour the blended shake into your chilled glass. Drizzle extra caramel sauce around the inside before pouring for a visual and flavor boost.
- Add toppings: Generously sprinkle the crushed speculoos biscuits over the top. Add whipped cream if desired. Only add the crumb at the end—this keeps their signature crunch.
- Serve immediately: Enjoy with a wide straw or long spoon. The shake is thick, so a standard straw may not suffice.
For the best results, use high-quality caramel sauce for depth and avoid over-blending. You can find more drink recipes in our copycat drinks collection.
How close is it to the original?
This home version mirrors KFC’s Caramel Krunch Shake in sweetness, creaminess, and the textural contrast of the biscuit topping. The exact crunch and spiced notes of the speculoos crumb may vary based on the brand you use, but the overall effect is very similar. Home blenders might not achieve the ultra-thick consistency of KFC’s commercial machines, and some reviewers note that homemade versions can be slightly less thick or even a touch sweeter if your caramel sauce is particularly sugary. Most reviewers agree the shake is “very sweet, creamy, and enjoyable,” with the crunchy topping as a highlight—though a few find it a bit sweet or not quite as thick as KFC’s original.
Troubleshooting
- Shake too thin: Too much milk or overblending can result in a runny texture. Stick closely to the 4:1 ice cream-to-milk ratio and blend only until just smooth.
- No crunch in topping: Blending the biscuits into the shake instead of topping it will dissolve their texture. Always add the biscuit crumbs at the very end.
- Shake melts too quickly: Pouring into a warm glass or working too slowly can lead to a thin shake. Chill your glass first and serve immediately after blending.
Variations
- Different biscuit brands: If you can’t find Lotus Biscoff, any speculoos-style or spiced tea biscuit will work, though the flavor may shift slightly.
- Salted caramel: Swap in salted caramel sauce for a deeper, less sweet finish.
- Dairy-free version: Use plant-based vanilla ice cream and oat or almond milk for a non-dairy alternative. The shake will be a bit less creamy but still satisfying.
Storage
This shake is best enjoyed immediately after blending. If you must hold it, store the base (without biscuit topping) in the freezer for up to 30 minutes, then stir and top with fresh crumbs before serving. The biscuit topping will lose crunch if stored for long.
