Are there carbs in coffee?
Yes, there are carbs in coffee but it depends on what type of coffee you are drinking and what else has been added. Plain regular unflavored instant coffee will have almost zero carbs.
Coffee is made from coffee beans, and beans have carbs, fat, and protein. How much of these macronutrients end up in your coffee will depend on how your coffee beans have been processed.
If your cup of coffee has been prepared from beans, the carb count will vary depending on whether it has been made using a plunger, espresso machine, dripped, or pressed.
These carbs in coffee charts show you exactly how many carbs are in each variety of coffee, which to enjoy and which to avoid.

Serving
Coffee and walnut bars are sturdy enough to pack for lunch, a hike, or a picnic. And sugar-free bars always make for a healthy mid-morning treat.
Use your favourite sweetener or sugar replacement to make whipped cream or cream cheese frosting to serve alongside these sugar-free coffee walnut bars.
Coffee and walnut bars can be served with whipped cream, whipped chocolate cream, or even add a splash of brandy to the whipped cream for a special treat for adults.
Are regular coffee bars keto?
Regular energy bars at stores would have misleading labels and make you think you’re about to buy something that will help you get through your day. But when you read all the ingredients, you’ll find that they're packed with added sugar as well as high carb oats and high starch grains, and not to mention the unhealthy oils.
Your blood sugars will be raised and you'll get that afternoon slump about an hour later. That's no fin for anyone.
But if you make your own homemade coffee walnut bar recipe, it is sugar-free, grain-free, and naturally gluten-free. It is a wonderful way to enjoy your coffee fix!
Storage
To help make your healthy lunchboxes fast, always have some sugar-free baking on hand in your fridge or pantry. It makes eating healthy convenient.
Because of the high egg content and natural unpreserved ingredients, these low-carb keto bars cannot be stored for long. But as long as you keep food safety in mind, they should last for up to 3 days fresh and up to 3 months frozen.
How to store for the next few days: Store in an airtight container on the kitchen bench for up to 3 days in cooler climates. Store in the fridge for up to 3 days when the temperature in the kitchen is warm or moderate.
How to store in the freezer: The sugar-free coffee walnut bars can be frozen in an airtight container for up to one month. Or why not make them as sugar-free coffee cupcakes? Easy and portable.
Are they gluten-free?
Coffee and walnut bars are naturally gluten-free because they are made with coconut flour. If you have never used coconut flour before, you need to read my Ultimate Guide to Low-Carb Flours.
Low-carb flours behave quite differently from traditional wheat flour. There is no gluten for elasticity and no sugar for volume, so there are a few simple baking rules you'll need to learn.
I have a number of recipes now that I make with coconut flour. Take a look at my Coconut Flour Recipe Finder. All the recipes in the coconut flour index, are either made with coconut flour or have a conversion so you may use coconut flour as an alternative in the recipe.

I have some coconut flour and want a cake recipe to use it up and saw yours.
I’m in the Uk and I know egg sizes vary between the UK, US, and Australia say. Just wondering which country you are writing this from so I can adjust eggs as necessary.
Libby Jenkinson
Hi Shelley, I am in New Zealand. These are the "average" sizes of eggs in different countries. In New Zealand our medium eggs are 44g, UK and European medium eggs are 53g, US medium eggs are 49g. So you would only need to adjust how many eggs a recipe uses if there was a large number of eggs in a recipe. Otherwise, most eggs range between 5-10g from each average value so on any given day (and any given tray of eggs) the weight will vary naturally.
Shelley
Thanks Libby. I use large eggs so I can now work out how many to use to be equivalent of your 8 x 44g medium eggs. Out of interest should the consistency be dropping or pouring when I’ve finished?
Libby Jenkinson
Awesome! The cake batter should be pourable.
Terry
Hi Libby- thanks for this recipe which I will be trying tomorrow. In the nutrition stats, you don't list the fat grams. Do you happen to have that number, please? Thanks so much.
Libby www.ditchthecarbs.com
My apologies, it has 11g fat. I have updated the nutrition panel.
Charlottesframe
Can you freeze these? 🙂
Libby www.ditchthecarbs.com
I have never tried but I am sure tye can be. I would freeze them sliced in an airtight container.
Ginger
I doubled the recipe and cooked it in a 9x13 pan. It took about 35 minutes. They turned out great! I thought it has more of a cake texture than a cookie texture. I brought these to school and they were a huge hit with everyone, even the non-low carb teachers.
Libby www.ditchthecarbs.com
That's brilliant!!! I love winning friends over with low-carb baking. Way to go!
Sherrie
Hi I've been busting my brian to figure out what 0.66 cups is...lol new to baking! Can you explain It to me better...thank you
Cassie
.33 is 1/3 cup so .66 is 2/3 cup
🙂

New to your site. Would like to make this recipe. What size pan did you bake it in. I need to know before I make it. Thanks for all your hard work!
Mahendra Joshi
you will love it. So much cheaper, healthier, versatile and easy to work with.

Hi Libby,
we use large eggs, what would the quantity be please and can this recipe be halved?
Libby www.ditchthecarbs.com
I would estimate (guess) that you could use 6 large eggs instead. And yes you can halve the recipe, simply dial up how many servings you would like to make, and as if my magic, the ingredient quantities recalculate for you - yay!
Kerry
Oh wow .... so so so good ... took 30 mins to cook and love

This may sound really silly, but what if I want to try this recipe... but I don't like coffee? I know... GASP! Would they taste okay using just water, or would I need to use a little coffee to get the right flavor? I like make-ahead, grab-and-go type snacks and this one sounded perfect for that (except for the coffee... LOL!). Thank you.
Libby www.ditchthecarbs.com
If you didn't add the coffee you would need to add some flavouring such as vanilla. But then the coconut flour: moisture ratio would be wonky. Why not try my other coconut flour sponge recipes instead. They are probably what you are after.
Kelly
Thank you so much! I'll give those a try.
Lynn
My husband does not like coffee and he actually likes the bread. Maybe give it a try? 🙂
Lynn
Thank you Libby for this yummy recipe. I made these a few days ago and they are delicious! I used my Nespresso too. I had to leave them in the oven for an additional 15 minutes though, so 30 minutes total baking time.
Christine Garlough
Could I substitute almond flour for coconut flour?
Libby www.ditchthecarbs.com
I'm afraid coconut flour and almond flour behave completely differently so cannot be substituted easily, instead they have to be developed into a new recipe. This article might help explain how they work and how little coconut flour is required compared wiht almond flour. Ultimate Guide To Almond Flour vs Coconut Flour
Ann Lampard
I just made these and they are scrumptious ! As a type 2 diabetic on Keto these tasted like coffee shop specials ! I will freeze and bring out as needed for a gorgeous treat. They make me feel ‘normal’. How nice is that !
Ginger
9x9 baking dish? Not seeing this info...
Sheryl
I was looking for that same bit of info.
M. J.
Me, too...what size dish, please, Libby?
Michelle Petropoulos
How about a vegan version? What can i use instead of eggs and butter?
Libby www.ditchthecarbs.com
Oooh, you've thrown me a tricky one with this request! I'm afraid this recipe in particular won't work =with so many substitutions because it is so heavy in eggs and butter. You're asking for a completely different recipe. But what an awesome request. I'll get my thinking cap on and see if I can come up with a vegan keto cake. Game on!
Angel
Hey when you say “strong coffee” do you mean just the instant coffee grains...? Or is it a cup of coffee? Do I make a cup of coffee with the boiling water? Or is it just the instant coffee grains?
Thank you!
Libby www.ditchthecarbs.com
You can use either. I generally use about 2 tbsp coffee in the hot water, or one strong espresso from my Nespresso machine. Go for it - you will know how strong you like the coffee taste. Some will like it subtle. Me? I like to knock my socks off with it.
Kjetil, Norway
Hi!
I am looking forward to try this recipe today. What size baking dish did you use?
Libby www.ditchthecarbs.com
Mine was a square 20x20cm (8x8 inch) ceramic dish. Enjoy 🙂
Kjetil, Norway
Thank you for response. I made i yesterday, and it turned out very good. ?
Libby www.ditchthecarbs.com
Awesome!
DavetteB
How do you get 14 bars from an 8x8 pan? Even 12 slices are really small.
Is more than 1pc a serving?
Thanks
Kjetil, Norway
Hi.
I thought I’d try this recipe today... How big is the baking dish you used?
Mary wood
Made these today and thoroughly enjoyed them ... thanks Libby.

Made these the minute we saw the post. Using your ingredients - the mixture seemed a bit runny - and we only used four (large) eggs. Is it supposed to be extra runny like that? So we compensated by adding a little extra coconut flour. The final product tasted okay, but a bit "spongy." Would more eggs have helped? Still can't quite crack the coconut flour recipes to our liking. May consider adding some vital wheat gluten to give it some buoyancy. And I wonder if some whipped egg whites would help too?
Either way - love these recipes regardless!
Libby www.ditchthecarbs.com
I wonder if you have the correct coconut flour? Some coconut flours aren't "defatted" (and so won't absorb as much liquid as true coconut flours do) but are more of a ground desiccated/shredded coconut mix which doesn't behave in the same fashion. I am so glad you enjoyed it anyway and are persevering with coconut flour. Once you find a brand you love, stick with it and you will love it. So much cheaper, healthier, versatile and easy to work with.

I used Jan's Organic Coconut Flour. Very fine powder. I also have used Bob's Red Mill in the past. Another note - we used Skinny Girl Stevia packets for the sweetening. Left a funny taste in our mouth. It was old, however, that may have contributed.
Having sweet things is a tricky endeavor. I think I'll stick with just the natural sweetness from fruits such as blueberries, etc. in the future.
