Whoopie Pies or Gobs? I don’t care what you call them as long as I can have one! Keto-fying this recipe makes it easy to enjoy this rich and delicious cakes!

There are arguments about the name of these delectable cakes as well as how to fill them. Some prefer a marshmallowy frosting, others a meringue style frosting while others prefer a cream cheese frosting. All fillings would be amazing for these low carb and high protein chocolate cakes. This particular recipe features a cream cheese frosting.

While traditional whoopie pies or gobs are a rich treat usually built around wheat flour and sugar, this version is a much healthier result based on a few key ingredients! Read on to see how you can make this keto version!

KEY INGREDIENTS

ALLULOSE

My true keto love! This sweetener tastes and behaves so similarly to sugar. It also helps keep baked goods like this nice and soft. Allulose is a rare, naturally occurring sugar that is very low in calories and well as low carb. It’s hands down my favorite keto ingredient. It’s the backbone of my baking.

OAT FIBER

This ZERO calorie fiber is usually used as a filler but in this recipe it makes up the bunk of the “flour” for our cakes. It is light and fluffy but can be a bit dry on its own. LifeSourse is absolutely my recommended brand. Other brands I’ve tried have been heavier and much darker and have resulted in a much less pleasant final product!

CASEIN AND WHEY PROTEINS

These are the two other main ingredients to our flour. They work together extremely well with the oat fiber to produce a light fluffy cake that is high in protein, so it’s healthy too!

TECHNIQUE

These Keto Whoopie Pies AKA Gobs are actually really easy to make! This is a very simple recipe that doesn’t require advanced techniques. Phew! If you wanted the sandwiches to be VERY precise, you could create a template on your parchment papers. Choose a round guide like a 12 oz can or a pint glass and trace circles on the parchment paper. Turn the parchment over (to avoid getting graphite on your cakes) and use the circles as guides for precisely making cake circles!

TROUBLESHOOTING

Why is my Keto Whoopie Pie batter dry?

This batter is naturally dry, but if it seems too dry did you omit the coffee and not replace it with almond milk? Double checking all the liquids, if it is still very dry, try adding an additional tablespoon of almond milk. The final texture should be stiff like a mousse.

How can I tell when the Keto Whoopie Pies are done?

Because these cakes are flat and the batter is light, they will cook quickly. Insert a knife at the thickest part of one and check that it comes out clean.

How to I prevent the Keto Whoopie Pies from cooking unevenly?

Try to ensure that the cakes are all the same size so that they’ll cook at the same rate. Also, rotate the pan half way through if your oven doesn’t heat evenly. I do not recommend using convection with this recipe.

SERVING

These would be great in many settings!

How to serve Keto Whoopie Pies:

  • For a birthday or kids party – they are cake sandwiches!
  • Great for a picnic or outdoor gathering; no cutlery required
  • Perfect for a potluck or to take to a party

Variations on this recipe

What should I drink with Keto Whoopie Pies?

MILK! That’s my first thought. A nice cup of coffee with some almond milk would be amazing too. Black tea would also be nice – maybe even some yummy iced milk tea!

STORING

With the frosting, these are best kept in the fridge. If you make the cakes ahead they can be frozen, defrosted then filled the day you plan to eat.

Ingredients
  

WHOOPIE PIES

    DRY INGREDIENTS

    • 1/2 cup oat fiber specifically LifeSource brand
    • 1/2 cup allulose
    • 6 tablespoons cocoa powder
    • 1/4 cup casein protein specifically Muscle Feast
    • 1/4 cup whey protein specifically Isopure
    • 1/2 teaspoon salt
    • 1/2 teaspoon xanthan gum I have omitted this successfully
    • 1/2 teaspoon baking soda
    • 1/8 teaspoon baking powder

    WET INGREDIENTS

    • 1 egg
    • 3/4 cup unsweetened almond milk
    • 1/4 cup avocado oil can substitute melted coconut oil or vegetable oil
    • 2 tablespoons Greek yogurt sour cream also works
    • 2 tablespoons coffee optional, if not used add 2 tablespoons of almond milk
    • 2 teaspoons vanilla extract

    CREAM CHEESE FROSTING

    • 8 oz cream cheese full fat block
    • 1 stick butter
    • 2-3 cups allulose powdered in a blender
    • 2 teaspoons vanilla

    Instructions
     

    WHOOPIE PIE INSTRUCTIONS

    • Preheat oven to 325 degrees F.
    • In one bowl, mix all dry ingredients.  Cocoa and protein powders can clump so be very thorough.
    • In a separate bowl, combine wet ingredients.  Slowly add dry ingredients to wet until the mixture is well incorporated.  The texture should be pudding-like.  If it’s too stiff, add another tablespoon of almond milk.
    • Line two sheet pans with parchment paper.
    • Scoop the batter onto the parchment making 2″ sized circles; leave room for cakes to expand as they bake.
    • Bake at 325 F and begin checking for doneness at 10 minutes.  Cake is done when set and a knife inserted at the thickest part comes out clean.
    • Allow to cool on a rack completely before filling.

    FROSTING INSTRUCTIONS

    • Cream room temperature cream cheese and butter until fluffy.
    • Add powdered allulose a little at the time until well incorporated. I prefer using 2 cups for a less sweet option.
    • Add vanilla and a pinch of salt, if using unsalted butter.
    • Pipe or spread onto fully cooled cakes and assemble your whoopie pies.
    • Enjoy!

      This recipe looks so good! I’ve never made homemade whoopie pies before but I certainly want to try now! Thanks for the recipe!

      • A friend from Pennsylvania (where they’re called gobs) introduced me to them. It’s been a love affair since then! I hope you’ll try and enjoy some soon!

    3. These look mighty tempting.
