Mug Blondie Ingredients

Let’s quickly run through what you’ll need to make this protein blondie. I’ll tackle common questions about ingredient modifications you might have.

Protein Powder

I used VanillaPEScience Select Whey and Casein Blend for this recipe. Interestingly enough, PEScience makes a blondie flavor in this protein, but I’ve yet to try it. If you come across it, that may eliminate the need for the next ingredient on the list.

Before we cover the sweetener, however, I’ll add that you can use any protein powder you like for this mug blondie. Another common protein powder I use is the Vanilla Cupcake Dymatize 100% Whey. I tested this recipe with both and found the Dymatize worked better with slightly less protein powder in the mix.

That’s why you’ll find a note in the recipe card about starting with 1/2 scoop instead of 2/3 scoop with other protein powders. It’s better to undershoot than have a dry or tough protein blondie, ya know?

Swerve Brown Sugar

Like I mentioned above, you mayfind that a blondie flavored protein powder alleviates the need for brown sugar. But I’m a proponent of buying vanilla protein powder since it’s a bit of a blank slate that can be turned into other flavors by adding ingredients like cocoa powder, brown sugar, etc.

In this case, I used Swerve’s brown sugar substitute. If you’re unfamiliar with Swerve, here’s a line straight from their about page:Swerve is zero-calorie, non-glycemic and measures cup-for-cup like sugar. It’s sweet, safe and natural.

If you don’t have Swerve on hand, the easiest swap would be plain brown sugar. The recipe only calls for half a tablespoon. So the calories won’t be affected too drastically.

Light Butter

When I say I tested this recipe 25 times, know that’s undershooting the real number. One of my most popular recipes is a one-minute, 100-calorie protein brownie that has just three ingredients—pumpkin, cocoa, and protein powder. And a modification for that recipe is using unsweetened apple saucein place of the pumpkin or going half pumpkin half apple sauce.

Honestly, I thought this mug blondie might be as simple as protein powder, apple sauce, and brown sugar. But it’s really difficult to mask the apple flavor without cocoa powder considering you need quite a bit of apple sauce to avoid a dry protein blondie.

Pumpkin and apple sauce are what I like to call lower calorie fat replacements. They mimic some of the properties of fat in a recipe—moisture, tenderness, binding—without actually having fat and all the calories. These ingredients have their limits, though.

So, the recipe calls for light butter, which is a favorite ingredient of mine. It has half the calories of regular butter and a little bit goes a long way in making high protein goodies fluffy and moist. That said, this long section about light butter and fat replacement is to show you there are other options, including other fats like coconut oil.

Final Notes

In case you’re wondering about the all purpose flour, my typical recommendation for swapping coconut flour is two or three for one. In this case, that would be 1/2 a tablespoon of coconut flour. If you go for something like almond flour, I might keep it at one tablespoon. This might take some tinkering on your end.

If you try this high protein mug blondie, make any modifications, or experiment in any way, I’d love to hear about it. Snap a pic and tag me on Instagram@mugsformusclesor join my freeFacebook groupand share it with the crew.
