Ingredients in the Pumpkin Spice Latte Custard Shake

Brewed Coffee

I include brewed coffee in the recipe because it’s sort of a key ingredient in the famous Pumpkin Spice Latte.

However, if you’re not a fan of coffee, no worries!

I love how this custard shake tastes when I make it with brewed chai tea instead of the coffee.

In fact, I might like it a little better with the chai tea!


The key ingredient in any custard is egg.

Eggs are what gives the custard its color and its rich flavor.

I love that they’re also a great source of protein!

This shake boasts 23 grams of protein, making it a healthy breakfast option.

How Can the Pumpkin Spice Latte Custard Shake be Considered a “Deep S”?

Trim Healthy Mama is a lifestyle where you separate your fuels.

In a nutshell, when we eat healthy carbs, we avoid fat; when we eat fats, we avoid healthy carbs.

You can read more about our experiences with Trim Healthy Mama here.

Meals that include fat are considered S meals (the S stands for satisfying). It’s easy to fall into the trap of loading up an S meal with lots of fat. I’ve definitely done that!

Deep S meals strip out certain kinds of fats (in particular, fat from dairy and nuts), and also contain virtually no carbs.

When should you have a Deep S meal?

Honestly, you should include deep S meals throughout the week.

These types of meals help you not overdo the kinds of fats that can lead to stalls.

Deep S meals are also a vital part of a fuel cycle, another tool to help if you find yourself at a weightloss plateau or stall.

Speaking of stalls, you might like my tips for breaking a THM stall.

The Deep S meal is what Pearl and Serene recommend as a “reset” if you indulge in off-plan foods at a meal!

Because sometimes when you follow this lifestyle, it’s gonna happen.

Fairly soon after beginning Trim Healthy Mama I found a recipe for a vanilla custard shake.

It tasted so good! But the amount of fat and protein in it was too high for me.

I began tweaking the recipe and playing around with other flavor combinations which is how I ended up with this PSL version!

I love that this recipe makes a really big shake!

It’s enough to be a full meal, or snack on its own.

If you choose to have one after a meal, you may want to cut the recipe in half.

Be sure to leave a star rating and review after you make the recipe!

This helps other people to find and enjoy it too.
