Keto Butter Coffee

Coffee lovers, I have great news for you, coffee is keto-friendly. Even better, you can make some delicious and easy keto coffee recipes that taste like your local coffee, at home in 5 minutes.

What’s a keto bulletproof coffee?

Bulletproof coffee is a popular keto breakfast drink created by Dave Asprey. It replaces your traditional cup of coffee or coffee latte. It is smooth and creamy as a latte coffee but does not contain any milk, sugar, or carbs.

Instead, it contains all the fatty acids you need to produce ketones quickly and keep your energy levels steady.

Keto Coffee Recipe with MCT Oil

Why should I drink bulletproof coffee?

On a keto diet, your body is in a shortage of carbohydrates and cannot produce use glucose as a source of energy. Instead, your body uses ketones, that can be consumed by your muscles or brain as an alternative source. So feeding your body with fatty acids that can quickly generate ketones is the key to:

  • Keeping your energy levels steady,
  • Feeling fulfilled and not hungry.
  • Increasing your focus and mind clarity.
  • Boosting your weight loss.

Bulletproof coffee is a coffee full of quality fat, like MCT oil and butter. MCT oil or Medium Chain Triglyceride is made of 3 fatty acids that have medium-length chains. It means they are broken down fast and they are quickly absorbed by your body to produce ketones, your source of energy in ketosis.

MCT oil in keto coffee goes straight into your liver to produce ketones. This means that bulletproof coffee helps you lose weight faster on a keto diet because it provides a quick and steady source of fat to give your body energy and fullness.

How to make this bulletproof coffee recipe for the keto diet?

Hot brewed coffee

Since you must blend your ingredients together, it is very important to start with hot freshly brewed coffee. Instant coffee will work too but the flavor of your keto coffee won’t be as good.

Quality fat

Bulletproof coffee is a simple combination of hot brewed coffee with:

MCT oil

MCT Oil increases the sensation of fullness, improves gut health, and on a keto diet, it also promotes fat burning as it gives a quick supply of ketones to your body. You can swap MCT oil for extra-virgin coconut oil, but MCT oil is far more concentrated. In fact, MCT oil contains is entirely made of Medium-Chain Triglyceride compared to about 50%-60% in coconut oil.

The main fatty acids from MCT oil are:

  • Caproic acid (C6)
  • Caprylic acid (C8)
  • Lauric acid (C12):  a powerful anti-fungal and antibacterial that shows benefits on gut health and helps people on a candida diet.

Grass-fed butter or ghee

Grass-fed butter is added to keto coffee for texture and creaminess. While it also adds healthy fat to feel fuel and keep your energy level steady, it adds a smooth texture that MCT doesn’t have. A rich, creamy texture to your keto coffee recipe while adding fulfilling fat.

Keto Coffee with Butter

A blender or immersion blender

A keto bulletproof coffee recipe is very easy to make with only 4 ingredients. However, the key to making a tasty keto coffee with butter is to use a blender! In fact, you MUST blend all your bulletproof coffee ingredients together on high-speed or the creamy coffee texture won’t form.

If you don’t blend your brewed coffee with MCT oil and butter, it will results in two layers, coffee at the bottom and fat on top. It won’t taste good at all!

Another option is to use an immersion blender or hand milk frother. Place all the ingredients in a tall mug, wide enough to fit your immersion blender or milk frother. Blend until creamy.

Bulletproof coffee and keto intermittent fasting

Does bulletproof coffee break your keto fast?

It’s the most common question on a keto diet. Technically, yes any calorie can break a fast. However, on a keto diet, fat is your fuel. So if you only consume pure fat, no protein, no carbs during you fast, you won’t break it.

Keto Bulletproof Coffee ZERO Carbs

It means that drinking a bulletproof coffee won’t hurt your fast at all. You will simply add more energy to your body and fullness that help you last your fast longer! So yes, you can drink one bulletproof coffee while fasting.

This will boost your fat-burning metabolism and help you fast longer without feeling hungry too quickly.

Should I drink bulletproof coffee if I am not on keto?

Since fat slows down your digestion, adding fat in your coffee creates a feeling of fullness and keeps your blood sugar level steady for longer.

It means that the benefits of adding fat or butter in coffee are great for anyone, not only people on a keto diet. However, keep in mind that bulletproof coffees are high in saturated fat, and not suitable for people with cholesterol or some other health issues.Bulletproof Coffee

Also, if your body is not fat-adapted, meaning it is not used to using ketones as a source of energy, it won’t have the weight-loss benefits it brings to someone following a keto diet.

What are the health benefits of bulletproof coffee?

The weight-loss effects of keto butter coffee are for people following a strict weight-loss keto meal plan. Some of the bulletproof coffee benefits you will experience after drinking bulletproof coffee on a keto diet are:

  • No energy crash, steady energy level
  • Fullness and less hunger
  • Increased mind focus
  • Weight-loss
  • Fighting the keto flu

What can I add to my butter coffee?

You can make your keto coffee even tastier by adding some of the following:

  • Collagen peptides – add 1 tsp of collagen powder, some are vanilla-flavored and will give a tasty vanilla flavor to your keto coffee.
  • Heavy cream – if you are not drinking this bulletproof coffee during your fasting period, feel free to add 1 tablespoon of heavy cream or unsweetened almond milk.
  • Sugar-free sweetener – make it sweet by adding safe keto sweeteners like 1-2 teaspoons of stevia drops or 1-2 tablespoons of erythritol.
  • a pinch of ground cinnamon on top – it doesn’t add carbs to your drink but a lovely cinnamon flavor

  1. First, I want to thank you for so many fabulous recipes! Just curious…why does MCT oil and grass-fed butter not break your fast but heavy cream will?

    • Thanks for following my recipes ! Well, heavy cream contains carbs 3.7 g per 100 ml but MCT oil, coconut oil or butter contains zero carbs its pure fat, so it doesn’t impact your blood sugar level or ketosis. I hope it make sense, Enjoy the coffee! XOXO Carine

      • 5 stars
        I’ve made this the past 2 mornings and haven’t missed the cream like I thought I would. Thanks for your reply…really appreciate the insight! 🌞

  2. I have come across FB group pages on Keto saying that putting hot coffee in a blender might lead to an accident where the blender explodes due to the hot liquids being put in the machine. But I see that you just put the hot coffee in your blender as seen on the video. Have you encountered/heard other stories like these before? It makes me scared to try blending my BPC since I have an Oster Glass blender and not like yours which I am guessing is more expensive. Thanks for the tips.

    • Not all blender can handle warm liquid, but most of them can, especially if yours has a glass jug ! Glass resist really well to high temperature. Simply refer to the manufacturer manual to be sure your brand can blend hot liquid. Mine is a Kitchenaid and can handle soup and any liquid between 190F and 210F so it can easily blend a freshly brewed coffee. Another option as mentioned in the post is to place all the ingredients into a coffee mug or large tall recipient and use an immersion blender or milk frother. Enjoy, XOXO Carine
