If you've worked hard this week (or even if you haven't), you deserve a treat. This keto milkshake recipe will have you feeling like you're at the neighborhood Dairy Queen while staying right within your macros.

If you’re anything like me, your relationship with sugar may have been the exact thing that led you to the ketogenic lifestyle.  

In fact, it was my nearly insatiable candy bar cravings that caused me to realize I had a serious sugar addiction.

While it only took about 30 days to break the sugar addiction, I still crave those decadent desserts I used to love so much.  Two of my old favorites were, of course, the Dairy Queen Blizzard and the McDonald’s McFlurry.  Both were so good but both are definitely not keto.

Ready for something yummy and delicious that definitely fits your macros? This easy keto fat bomb Reese's Cup milkshake is ready to satisfy all of your sweet tooth cravings.

If there’s anything great that the keto diet has brought us, it’s the delicious, delicious fat bomb.  I mean, c’mon, who is the genius who thought that up?  She’s right up there with the guy who invented fat head pizza dough.  

“The hero we need…” and all that.

Keto Milkshake Base

Anyway, I love the whole fat bomb idea and wanted to incorporate it into a milkshake.  That’s why we start with 2/3 cup of full fat coconut milk or coconut cream.  Adding the avocado makes the shake extra creamy while keeping it healthy and dairy-free.

For the flavorings we use standard Cocoa Powder to achieve our chocolate base.  Next, we add both natural peanut butter and peanut butter powder.  Finally, we sweeten it up with liberal amounts of Swerve sweetener and sugar-free peanut butter syrup.

Keto Milkshake "Reese's Cup" Add Ins

Okay, so we couldn’t use actual Reese’s Cups in here and keep it keto.  We had to get creative.

I mentioned before that I like my milkshakes chunky…ala, The Blizzard, and I didn’t want to sacrifice here.  I found these Lily’s Chocolate Peanut Butter Cups at the grocery store and knew I had to try them.

These worked perfectly and one was enough to add significant chunk to this already decadent milkshake.

NOTE: Freeze the peanut butter cups for 30 minutes prior to cutting into chunks to keep them from sticking together.  They are much easier to work with.

Keto Milkshake Topping Ideas

When making a milkshake, I feel like the toppings are the most important part.  C’mon, would you just look at that picture.

For this recipe, I just kept it simple. 

A little homemade whip cream (just heavy cream and Swerve sweetener) from this handy whip cream dispenser.

Finally, we top the whip cream with the remaining chopped candy bar.

Absolutely delicious and a treat the whole family will love.

  1. If you don’t have the PB syrup or powder will this still turn out? 😛 I could buy powdered PB but syrup would be impossible to find in Canada.

    1. Yes, you can make adjustments as needed. If you don’t have the peanut butter syrup or the powder, up the amount of peanut butter and maybe add a bit of keto-approved sweetener. The syrup helps sweeten the milkshake.

  2. 4 stars
    Really good. I struggle with this diet because I’m not too much of a meat eater but I’m also lactose intolerant. So was kind of like the perfect fit because I love chocolate and I love peanut butter. I didn’t add the lessee or the whipped cream but it still turned out amazing and I will definitely have this again especially probably in the morning because I do not eat breakfast. I would love to see other milkshakes or smoothies for this diet. ❤️ -Ishi

    1. Thanks for the input Ishara and I’m so glad you liked this Keto Reese’s Cup Milkshake recipe. I plan on doing some more milkshakes in the near future and I love making them with coconut milk as opposed to heavy cream since it just agrees with my stomach better. I’m not necessarily lactose intolerant but too much dairy can cause problems.
