Keto Iced Bulletproof Coffee — a creamy, frothy, and energizing low-carb coffee drink made with high-quality coffee, MCT oil (or coconut oil), and unsalted butter or ghee. It’s a perfect fat-forward beverage for keto mornings, a satisfying pre-workout pick-me-up, or a creamy iced treat that keeps you in ketosis.

I discovered Bulletproof Coffee early in my keto journey — it quickly became my go-to when I wanted something more than plain black coffee. The iced version is my favorite in hot weather: rich, smooth, and it keeps hunger at bay until lunch. Over time I tweaked the ratios until I found the perfect balance of creaminess and clean energy without the sugar crash.
๐งพ Ingredients (1 serving)
- 1 cup (240ml) strong brewed coffee, cooled
- 1 tbsp MCT oil (or coconut oil)
- 1 tbsp unsalted butter or ghee
- 2 tbsp heavy cream (optional)
- Ice cubes
- Few drops liquid stevia or 1–2 tsp powdered erythritol (optional)
- Optional: 1/4 tsp vanilla extract or a pinch of cinnamon
๐จ๐ณ Instructions — Step by Step
- Brew & chill: Make a strong cup of coffee using your preferred method (French press, espresso, or drip). Let it cool for a few minutes or chill in the fridge if you prefer a very cold drink.
- Combine in blender: Add cooled coffee, MCT oil, unsalted butter/ghee, heavy cream (if using), and sweetener or vanilla to a blender.
- Blend: Blend on high for 20–30 seconds until frothy and emulsified. This creates a rich, latte-like foam without dairy sugar.
- Serve: Place ice in a tall glass. Pour the blended coffee over the ice and finish with a light dusting of cinnamon or a few coffee beans for presentation.
- Enjoy: Drink immediately for best texture and flavor.
- Use freshly brewed, good-quality coffee — the flavor matters more since this recipe is fat-forward.
- Room-temperature butter blends more easily; if your butter is cold, blend a little longer to emulsify.
- For a dairy-free version, skip heavy cream and use full-fat canned coconut milk (use the thick part) or increase MCT/coconut oil slightly.
- Start with 1 tablespoon MCT oil; if you’re new to MCTs, try 1 teaspoon first to assess tolerance (MCTs can cause stomach upset in some people when taken quickly).
- If you don’t have a blender, use an immersion frother or a milk frother to emulsify the fats — but a high-speed blender gives the best foam.

๐ฅ Why this works for keto
This iced Bulletproof Coffee focuses on healthy fats (MCT oil and butter) to provide steady energy and support ketosis. The fats help keep you full and stabilize blood sugar compared to sweetened coffee drinks. MCT oil in particular is rapidly converted into ketones, which some people find helpful for mental clarity and energy on keto.
๐ Variations & Add-ins
- Vanilla Almond: Add 1/4 tsp vanilla extract and use unsweetened almond milk for a nuttier flavor.
- Mocha: Add 1 tsp unsweetened cocoa powder and a touch more sweetener for a chocolatey twist.
- Spiced: Add a pinch of cardamom or cinnamon for a cozy spice profile.
- Collagen boost: Stir in 1 scoop of unflavored collagen powder for protein and joint support.
๐ง Storage Tips
Because this is best fresh for the emulsified foam, I recommend enjoying it immediately. If you must store, keep the blended mix (before adding ice) in a sealed jar in the fridge for up to 24 hours. Re-blend or shake well before serving over fresh ice.
❓ Frequently Asked Questions
- Is Bulletproof Coffee safe every day?
- Many people enjoy it daily as part of a ketogenic routine, but consider overall dietary balance — rely on whole foods for meals and not just fats. If you have medical conditions, check with your healthcare provider.
- Will this break fasting?
- Yes — because it contains calories from fat. It’s not suitable if you’re trying to maintain a strict water-only fast, but some people use Bulletproof Coffee during intermittent fasting windows intentionally for fat-adapted energy.
- Can I use olive oil instead of MCT oil?
- Olive oil has a different flavor and fatty acid profile. It can work in a pinch, but MCT oil is preferred for a neutral taste and rapid ketone production.
I usually make this in the morning before work — it keeps me focused and satisfied. If you're new to MCT oil, take it slow and find the amount that works for your digestion. For hot months, iced is unbeatable.
