Egg Coffee

I’ve been following Mark Sisson’s writing on nutrition since we spoke at the same convention in Orlando together a few years ago, and enjoy some of the more unconventional recipes he shares from time to time. Recently, someone shared an article he wrote about adding egg yolks to coffee after he heard about Vietnamese egg coffee, so I decided to give it a try.

Egg coffee

Four egg yolks, mixed and slowly stirred into to sixteen ounces of coffee with a fork produced a smooth, creamy taste that was much lighter than I expected and surprisingly did not taste like yolk at all. Unlike butter and coconut or MCT oil, which do not blend well with a fork and tend to separate after a while even when mixed with a blender, the yolk and coffee mixture remained consistent. Yesterday I tried adding a heaping tablespoon of coconut oil, just to see how it would mix, and although the eggs still mixed smoothly the coconut oil separated and started to pool at the top after a few minutes. Today I figured I’d give the Vietnamese version a try, and whipped four egg yolks and a two tablespoons of sweetened, condensed milk  in the bottom of the mug (as opposed to the one egg yolk and two teaspoons the recipe called for) before stirring in the coffee. It blended perfectly, and tasted great (while adding about 120 calories).

If you’re trying to increase your protein and calorie intake, you can’t go wrong with eggs. A dozen extra large egg yolks will give you around 660 calories and 36 grams of protein. If you save the whites to mix in a smoothie or shake the total goes up to about 960 calories and a substantial 84 grams of protein. All for less than three dollars. By comparison, a single serving of most weight gain powders costs between three and five dollars, and only provides about half the calories and protein (for example, Weider Mass Gainer 2000, costs $3.66 per serving, with only 400 calories and a meager 25 grams of protein – most of the calories come from maltodextrin). Use one yolk for every four ounces of coffee, or two per cup. Separating all those yolks quickly becomes a pain in the ass, so if you plan to try this I recommend getting a good egg separator. I picked up a Good Grips 3-in-1 Separator this morning which has an edge for cracking and sits right on the edge of a bowl or glass, and made the process much easier.

After separating the yolks add them to a separate container for mixing, optionally along with your choice of sweetener. When pouring your coffee, make sure to leave enough room for the yolks, then slowly pour them in while stirring with a fork. They mix very easily so you don’t need to mess with a blender, which makes one less thing you have to wash later.

Give it a try and let me know what you think, or share your own recipe in the comments below.

    (Hey, your four yolks + condensed milk are >200 calories, not 120. From a tracking obsessive.)

    This seems much more appealing than Bulletproof Coffee, though I still prefer to eat my calories with a fork.

    My go-to salad dressing is 1TB of coconut oil, cooked ~1m in the microwave until liquid and hot, then mixed together with 2-4 egg yolks.

      The 120 calories are from just the condensed milk, not the eggs. With the four extra large egg yolks and the two tablespoons of condensed milk it is around 340 calories.

      Thanks for the salad dressing idea, I’ll give that a try.

        Hi Drew,
        I’m adding the coconut butter on my diet. What the daily doses? Thank you.

          It depends on your nutritional requirements. If you need more fat, use more. If you’re already getting plenty of quality fats from meat, fish, and eggs, use less. I usually put one tablespoon in each of the three sixteen ounce mugs of coffee I usually drink between six o’clock and noon.

    or you can try this very simple method to separate egg yolks.

    • Drew Baye January 8, 2014 at 4:29 pm #

      This is better than the old shell transfer method, but using the Good Grips egg separator or something like it is still faster. With the separator on the lid of a bowl you just crack the egg into it, the white goes through into the bowl, and you dump the yolk in another container. Also, I’d be concerned about breaking the yolk with the bottle if you’re not careful.

    Hi Drew,

    Nice tip! However, be careful about consuming those raw egg whites in a smoothie. This is from Chris Masterjohn:

    Raw Egg Whites Contain Digestive Enzyme Inhibitors and Anti-Nutrients

    Raw egg whites should not be consumed. They contain inhibitors of the digestive enzyme trypsin, which are destroyed by heat. Consuming 100 grams of raw egg white with one egg yolk compared to consuming the same food cooked was shown in one study to reduce protein digestion from 90 percent down to 50 percent.

    Raw egg whites also contain an anti-nutrient called avidin. Avidin is a glycoprotein that binds to the B vitamin biotin, preventing its absorption. Biotin is necessary for fatty acid synthesis and the maintenance of blood sugar, and is especially important during pregnancy when biotin status declines.

      Thanks for the heads up. I’ll stick with the yolks for the coffee and dump the whites or save them for cooking.

    • Stevo September 3, 2015 at 12:54 pm #

      Whenever I consume raw eggs, I take a Biotin supplement at the same time; offsets Avidin concerns, and adds about $4-5/month to the budget.

      • Drew Baye September 3, 2015 at 5:16 pm #

        Hey Stevo,

        I only put the yolks in coffee and discard the whites, so avidin binding biotin isn’t a problem.

    Coffee? Don’t need the catecholamines. Get a better, cleaner boost from yerba mate. No catecholamines – as long as you keep the water under 195 – plus theobromine to boost mood.

    I’m about to do another cup now.

    • Drew Baye January 10, 2014 at 2:03 pm #


      I’m not worried about the catecholamines and not a fan of yerba mate, and although it might turn out to be nothing, there is research showing a correlation between yerba mate intake and oral cancer. I’ll stick with coffee.

      • Dave January 10, 2014 at 2:12 pm #

        Catecholamines depress physical performance. Studies using pure caffeine as a supplement show a boost. Coffee does not and that’s the reason why. I’ve verified this in my own workouts.

        That cancer study has been fisked; don’t have the link handy.

        • Drew Baye January 10, 2014 at 2:40 pm #


          I’ve done fine with “bulletproof” coffee (grassfed butter and MCT oil) and plan to continue drinking it with egg yolk for a while to gauge the effect. I don’t care much for tea, but I might give yerba mate a run in the future.

          • Dave January 10, 2014 at 2:47 pm #

            Fair warning: Taste-wise I’d *much* rather drink a good cup of coffee. And your egg coffee sounds magnificent.

            I’ve had real Kona twice. The first of which was one of the great taste experiences of my life. Second was pretty good too.

            Thanks to no catecholamines and the theobromine the kick is smooth and no jitters.

            Though, as in my coffee days I take two days off per week to avoid adrenal exhaustion.

    Sounds like it would make quite the pre workout… While on this subject is it true you shouldn’t have saturated fats around a workout as they slow down digestion therfor slow delivery of nutrients to the muscles?

    • Drew Baye January 13, 2014 at 9:14 am #


      No, the problem with consuming fats too soon before a workout is they slow down the rate your stomach empties into your duodenum so they can be more effectively broken down and absorbed. If you have a high fat meal too soon before a high intensity workout you better have a puke bucket handy.

    What Drew said! I couldn’t believe how good ot tastes!
    I’m starting a 2 week cutting diet, so obviously I’m looking for low carb options. During this trial, I will not be using cream and sugar like I usually do. It mixes smooth and consistent and lightens the coffee like cream… And tastes creamy.

    Asked my wife to try it and she gave me a definitive “ew!” She tried it and was surprised.

    For those who are leary of raw eggs, let me assure you that it is lightly cooked by the temp of freshly poured coffee. Like hollandaise sauce, it thickens without curdling.

    Leftover whites are mixed with whole eggs to scrabble or for omelette.

    Don’t knock it til you try it.
    Thank you, Drew, for a great tip!

    • Drew Baye January 17, 2014 at 3:08 pm #


      I was surprised as well. It doesn’t taste at all what I expected. It’s a good option if you’re trying to reduce carbohydrate intake, but don’t drop your carbs too low, as doing so may cause an increase in cortisol and decrease in testosterone levels.

    Hey Drew,

    Any advice for trying to consume more protein? I am 140 lbs, ~10-15% body fat, so 1g protein per lean body mass would come out to ~120g of protein/day. Over a carton of eggs a day? Shit.

    • Drew Baye January 18, 2014 at 2:57 pm #


      Eat more beef. If you’re trying to increase protein intake without increasing calories too much, choose leaner cuts or leaner ground beef.

      • Wade Gwin January 18, 2014 at 4:14 pm #

        Alright, I’ll give it a shot. As always, thanks for the advice, Drew.

        • Drew Baye January 18, 2014 at 4:22 pm #


          You’re welcome. Cool notebooks on your web site, BTW. Those would make great training journals.

          • Wade Gwin January 18, 2014 at 4:33 pm #

            I wish you could feel the leather… It’s so soft—just makes you want to use it. Thanks again.

            • Drew Baye January 18, 2014 at 4:37 pm #


              I used to own a lot of leather, got rid of it after I got engaged since my wife wasn’t into that sort of thing.
