Healthy Deep Dish Sugar Cookie takes the classic to a whole new level – high protein, low carb, sugar free, lower fat and still has the soft, thick, and chewy texture.

I’ve gotten a number of requests recently for recipes with almond flour, and really wanted to give something simple a try. And yes I say simple because I know that baking with almond flour can be quite tricky. Tie that in with baking with protein powder and you’re just creating trouble.

A lot of thought later I decided to go for this single serve deep dish sugar cookie. All the festive holiday vibes, plus the low carb factor from almond flour and high protein factor from the protein powder.

Best part is that it’s still a fairly lower fat and lower carb recipe for the portion size! And it’s a single serve recipe that has no butter!

So let’s dive in!

Ingredients for Healthy Deep Dish Sugar Cookie

This single serve protein birthday cake is made with a few simple and healthy ingredients, and has no flour, butter or oil and no sugar either!

Vanilla Protein Powder for sugar free sugar cookie. I used Quest Nutrition Vanilla Milkshake whey-casein protein powder for this recipe.
Almond Flour – I used this one from Nature’s Eats, but you can use any other brand.
Or even regular flour if you don’t need to do low carb.
Unsweetened Appledauce
Unsweetened Almond Milk
Baking Powder
Sprinkles

If you need to add more sweetness, Stevia Powder or Zero Calorie Sugar Substitute; I use Lakanto, to keep the sugar cookie sugar free; (code HAYLSKITCHEN for a discount here too)

Can I use other Flour for this sugar cookie in a mug?

I used almond flour, but you can replace this with other options too.

Cashew Flour or Oat Flour for a gluten free option
Regular all purpose flour, or even whole wheat pastry flour (not whole wheat flour. The pastry flour)
1:1 Gluten Free Baking Flour would also work just fine.

How can I make this Protein Sugar Cookie Mug Recipe Vegan?

There’s no butter in this single serving protein sugar cookie mug, so you can easily make it Vegan with a few simple substitutions:

Protein Powder: Replace Whey-Casein with a plant-based protein powder. Be sure to choose one that you enjoy the flavor of, as it will significantly impact the overall taste of the cake.
I also recommend adding a bit of vanilla extract and sweetener in this case since plant based protein powders have a bit of an earthy taste.
Egg White: I haven’t tried this myself, but try a flax egg instead! Or maybe even aquafaba (chickpea liquid)
Sprinkles: Be sure to use sprinkles that are plant-based.

What if I don’t have applesauce?

Feel free to use mashed banana or pumpkin puree, but this will alter the flavor of the cake a little.

Can I use other milk in this deep dish protein sugar cookie?

You can use any other plant-based milk you prefer, such as soy milk, oat milk, or cashew milk. Regular milk in 1% or 2% would also work just as well.

How to make Deep Dish Sugar Cookie with Protein Powder

This protein powder deep dish sugar cookie really is a simple one, and here’s how to put it together:

Preheat oven to 350°F (175°C). Make sure your oven rack is in the center position for even baking.
Lightly grease a 1 cup ramekin. You can use cooking spray or a small amount of oil or butter. Greasing the ramekin will prevent the cookie from sticking.
In a mixing bowl, whisk together the vanilla protein powder, almond flour, and baking powder. Make sure there are no lumps in the dry ingredients.
Add the unsweetened applesauce, almond milk and egg to the dry ingredients. Stir until just combined.
Taste the batter and add sweetener if needed. If you prefer a sweeter cookie (or your protein powder is not sweet enough), you can add a small amount of stevia or your preferred zero-calorie sweetener.
Gently fold in the sprinkles.
Pour the batter into the greased ramekin. Smooth out the top with a spatula.
Bake for 20ish minutes, or until the top of is just set. You can insert a toothpick into the center of the cake to check for doneness. If it comes out moist but not fully wet, it done.
Let the cookie cool slightly before eating.

How to Store Single Serving Low Carb Sugar Cookie:

This single serving low carb sugar cookie is really good and easy to finish, but just in case you have leftovers or want to make it ahead and save some for later, here’s how:

Room Temperature: Simply cover the ramekin with plastic wrap or aluminum foil and leave for a few hours.
Refrigerator: For longer storage, refrigerate the healthy protein deep dish sugar cookie for up to 4 days. Make sure to cover it tightly to prevent it from absorbing other flavors in the fridge.
