Keto Grasshopper Bars get a delicious low carb update. These fudgy low carb chocolate brownies with a minty buttercream filling and a sugar-free chocolate topping are sure to please.
I’ve been having some fun lately going back through old recipes and seeing which of them might be worthy of a little update. Some I update because I’ve discovered a new way of doing things that applies to the recipe in question. Some I update because while it was pretty good back then, I know I can do better now.
And in almost all cases, they can use new and improved photography. In this particular case, all three of these things seem to be true. My low carb Grasshopper Bars are quite a popular recipe but they are more than five years old now. Time for an update to make them tastier, healthier, and even easier to make!
How to make Keto Grasshopper Bars
Back in those old days, I was still searching for a brownie recipe that met my high expectations for rich, fudge-like chocolatey goodness. Nothing I was creating really came close for that fudgy texture I was so desperately seeking, although the flavour was pretty good.
But I’ve since perfected my low carb brownie recipe and have used it numerous times, in my Double Espresso Brownies, my German Chocolate Brownies, and my Almond Joy Brownies. It is, in my humble opinion, the perfect brownie base because it can be taken out early for extra fudgy-ness, or baked a little longer for more cakey brownies. It’s up to you.
Also in my nascent blogging days, I didn’t realize that there were healthier, more natural ways to get a lovely minty green colour for the filling. Of course back then I just plopped some green food colouring in and called it a day.
Since that time, I’ve discovered that a number of great natural food coloring options. I really like using these vegetable based powders from Color Kitchen. I will warn you, however, that they are quite powerful and have a tendency toward neon vibrancy if you use too much of it. I usually sprinkle a beat in just a little at a time until I get the color I want.
I also used plain erythritol back then, which has that strong minty cooling sensation. That was actually a good fit for Grasshopper Bars, but I didn’t love it in other things. And since I’ve discovered Swerve, which give me no cooling sensation, I haven’t looked back. Also using Lily’s Baking Bar for the topping means I don’t have to worry about trying to get sweetener properly whisked in to unsweetened chocolate, which is almost impossible to get perfectly smooth.
Dairy Free Grasshopper Bars?
One extra little twist that I threw at this new version was using dairy-free cream cheese for the filling. I find that cream cheese gives a low carb “buttercream” more structure so I don’t have to use quite as much powdered sweetener. And I have wanted to try using the Kite Hill almond milk cream cheese in a regular dessert, hoping it would hold up and taste as good as regular cream cheese. It certainly was!
My next-door neighbour, who was going to be partaking of these little bars, eats no dairy besides butter (the whey and casein in most dairy bothers him). He absolutely raved about these so I sent him home with the leftovers and a big thumbs up for Kite Hill almond milk cream cheese.
If you want to make the bars completely dairy-free, try coconut oil in place of the butter in the bars, filling, and topping. Make sure it’s slightly softened but not entirely melted before beating it in.
- 1 1/3 cup almond flour
- 3/4 cup Swerve Sweetener
- 1/3 cup cocoa powder
- 1 tsp baking powder
- 1/4 tsp salt
- 1/2 cup butter
- 4 ounces unsweetened chocolate chopped
- 5 large eggs
- 1/2 tsp vanilla extract
- 1/4 cup to 3/4 cup water
- 8 ounces cream cheese softened
- 1/2 cup butter softened
- 2/3 cup powdered Swerve Sweetener
- 1 1/2 tsp peppermint extract
- Natural green food coloring
- 5 ounces sugar-free dark chocolate chopped
- 1 tbsp butter
-
Preheat oven to 300F and grease a 9x13 inch baking pan well.
-
In a large bowl, whisk together the almond flour, sweetener, cocoa powder, baking powder and salt.
-
In a medium saucepan, melt butter and unsweetened chocolate together over low heat, stirring until smooth. Add to almond flour mixture.
-
Stir in eggs and vanilla extract. Whisk in just enough water to make batter pourable, but not too thin. Pour batter into prepared baking pan and smooth the top.
-
Bake 25 to 30 minutes, until just set in the center. 20 minutes for more fudgy brownies, 30 minutes for more cakey brownies. Remove and let cool completely.
-
Beat cream cheese and butter together until smooth. Add sweetener, and peppermint extract until well combined and smooth. Add green food coloring until a light minty green is achieved. Spread over cooled brownie base and refrigerate until firm, about 1 hour.
-
In a heatproof bowl set over a pan of barely simmering water, melt chocolate and butter together, stirring until smooth. Spread over chilled filling and let set, about 20 minutes.
JENNIFER ASHER says
These look amazing! I can’t wait to try them. I get a very strong cooling sensation from swerve 🙁 I wonder why some do and some don’t?
Carolyn says
Every palate is different. It’s the only one I DON’T get the cooling sensation from.
Julie says
“you can also substitute 1/4 cup of the Swerve with 1/4 liquid stevia extract)”
1/4 what of liquid stevia?
Carolyn says
Just any liquid stevia extract…comes in a bottle with a dropper.
Jen R says
I think she meant what measurement (teaspoon, tablespoon, etc) 🙂
Carolyn says
Ah. The question “what kind” was confusing. Recipe is fixed!
Carolyn says
1/4 teaspoon
[email protected] A Dash of Cinnamon says
These look so good! They look a bit like Andes mints lol
Cathi says
Also wondering what kind of stevia!
Carolyn says
Just any liquid stevia extract…comes in a bottle with a dropper.
Carolyn says
1/4 teaspoon, btw.
janet says
Is the Matcha tea just for color or does it have some other use in the recipe?
Can I just leave it out, cause I don’t have any and I REALLY want to make these today!
Carolyn says
Just for colour.
Autumn says
I would love to make these, but the Lily’s chocolate upsets my stomach, do you have a general amount of sweetener I could add to unsweetened chocolate instead for the topping? I know it won’t be as smooth, but it’s worth it for my stomach!
Carolyn says
Make the topping from this recipe: https://alldayidreamaboutfood.com/2015/09/low-carb-death-by-chocolate-cheesecake.html
Deb says
I needed this recipe yesterday! Today was our church picnic and I’m known for my creme de menthe brownies. I made a THM cake instead; it just wasn’t the same. Can’t wait to try this some day!
Carolyn says
I hope you love it when you do try it!
Ashley says
These grasshopper brownies are so good, I could literally cry. I had to package half of them up and bring them to work because otherwise I would have managed to eat them all myself! My co-workers loved them, by the way, and couldn’t even tell they were low carb!
One question – is the total NET carb count 6.01 or 2.35 (after subtracting the fiber)? I’m never sure when it’s OK to subtract in a baked good and when it’s not.
Thanks for the amazing recipe!
Carolyn says
The net carb count is right at the top, 2.35g. The total carb count is 6.01 but that is before subtracting the fiber.
Ashley says
D’oh. Great reading comprehension, me. I must have been drunk on chocolate;)
Carolyn says
No worries!
Stephanie says
Do you use salted or unsalted butter in this recipe?
Paige says
Ok, I made these a few days ago and they. are. amazing. So rich, but not too sweet. Great top off dessert to end the day with.
Spaceranger says
OK, I have been tearing through your dessert recipes and they are amazing. As a kid my favorite Christmas treat was grasshopper brownies. I made your version today. I looooove them. Also, I pretty much always have matcha green tea powder on hand, but not green food coloring. Also I hate feeding my kids food coloring. I was sooooooo happy to color these with matcha. Such a great idea. For the very top layer I used the ganache recipe from your nanaimao bar tarts because I really like it. I don’t regret doing that. I went for more “cakey” brownies so baked the brownie layer for 30 minutes. , That layer is a little dry and crumbly. Is that common for the 30 minute version, or did I maybe do something wrong? If (when) I make these again, I’ll try baking the brownie part for only 20 minutes, but I do prefer cakey for this particular dessert. Thanks a million! I”m a huge fan!
Laureen says
WOULD these freeze ok?
Carolyn says
They would be fine, I think.
Samantha Hill says
wow these were fantastic for Christmas – the kids didn’t realise that they were healthy – but nor did I tell them. I almost missed out – I got only 1 and a bit slices. I didn’t use matcha powder just green food colouring and I also added a couple of sheets of gelatine to make sure it held up ok. Perfect. I will do it again.
Thanks for the recipe, nice out of the fridge on a hot summers day here.
Kathy says
Any replacement ideas for Swerve? Need to look up what’s in there. Don’t usually like sweeteners.
Kathy Poche says
What purpose does the matcha green tea powder serve? Is it a flavoring or more for color?
Carolyn says
Colour!
Deborah Kloss says
I used chlorophyll drops for the coloring…worked great!
Elizabeth says
Delish! Brownie base is a winner; thought I over-cooked them (25-26 min at 300 in a coated metal pan), but center ones remained fudgy, edges more cakey. Like others, I get the cooling sensation with stevia sweeteners (even with Swerve), but the mint really is perfect for this. The most challenging part for me of following a ketogenic diet has been the lack of baking my old standards, so thank you so much for your passion for baking!
Stacey says
Do these have to be refrigerated?
Carolyn says
Yep, that’s the best for them. They are okay for a few hours on the counter.
Guinan says
I always get confused about the “unsweetened” chocolate. I can buy chocolate with sweeteners – no sugar. And I can also buy completeley unsweetened, no sweetener, no sugar, no nothing.
How do you diferenciate between the two?
Carolyn says
Unsweetened chocolate is chocolate with NO sweeteners and will often say 100% cacao or cocoa. Sweetened chocolate, even it it’s sugar-free, usually says “dark chocolate” “milk chocolate” etc. When in doubt, look at the ingredients.
Carolinagirl says
You are a genius, these were amazing! This was my first keto Christmas, and i was making our usual paleo goodies for my husband and kids. One of my favorites was a paleo Thin Mint cookie, and i was delighted to find this recipe to have while they were having their Thin Mints. My son even liked this recipe better than the Thin Mints! I have made several of your recipes for the holidays and birthdays, and i truly appreciate the options you have given me to still be have a special treat on a special occasion!
Carolyn says
So glad you liked them!
krissy says
You had me at chocolate and mint! These are incredible. A new family favorite!
Natasha says
These are fantastic – the colors and flavors are just right – these can easily pass as elf brownies for Christmas. YUM!
Jessica says
Thank you so much! Love this recipe!
Becky Hardin says
These look so incredible!! Chocolate and Mint together are one of my favorite combos.
Anna says
Loving this low carb version of grasshopper brownies! So delicious!
Megan Oehley says
Would Lily’s chocolate chips work for the chocolate topping?
Carolyn says
Sure!
Sue says
I’d like to make a half batch in an 8×8 pan. Would it be better to use 2 eggs or 3?
Sue says
I made these in May and had some left over. Put them in the freezer for the whole summer since I was leaving town. Just got back in town and found them in the freezer, not remembering I left them there. Bonus! Left them in the refrigerator overnight to thaw and they are so good.
Carolyn says
Like money in your pocket!
Joan says
I just got done making them. These were so yummy! The only issue I had was that I couldn’t get the chocolate topping to spread enough all the way across my 9X13 pan. So I ended up melting more chocolate and topping it again. Then when cutting them, my chocolate cracked in many of the bars. I couldn’t figure out how to get 25 bars out of the pan so I cut them into 32 and that amount was fine as they are very rich. I tried to use a heated knife and oil sprayed knife, but they cracked. The taste was worth the effort to make these, but I wish I could nail the presentation. My topping looked nothing like yours. My chocolate wasn’t shiny either, it got dull after I took it out of the fridge. I would love any tips you have to get a better presentation.
Carolyn says
What brand of chocolate did you use?
Monica says
I want to thank you for your fabulous cookbooks and recipes!!! These were absolutely delicious!!! I kept them in the refrigerator. I used Swerve granular for the sweetener For the brownies and I noticed a crystallization feeling in the brownie portion after a couple of days. Should I use powdered swerve for brownies? Or any other suggestions? Thank you!!
Alyson Stewart says
I LOVE your best brownies recipe you’ve posted since this grasshopper recipe came out. Could I swap it in for the brownie base in this recipe?
Carolyn says
Sure but you will need more of it. I would increase the ingredients in the brownie batter all by 30%.
