Coming Up With A Healthy Substitute

Do you know that before I made low carb keto a lifestyle, Reese’s Peanut Butter Cups were a regular part of my life? Fast forward, and a real Reese cup hasn’t crossed my lips.

BUT….by no means that I suddenly stopped loving the combination of peanut butter and chocolate.

However, traditional chocolate and peanut butter bars no longer fit my lifestyle.

So, a new healthier version needed to take its place.

Creating a low carb treat like these keto peanut butter swirl brownies gave this girl an excuse to enjoy chocolate and peanut butter goodness.

AND…it gives you another easy keto treat to try.

This recipe starts with a peanut butter base and then get’s a MASSIVE dose of chocolate with a fudge swirl.

Quality Of Ingredients Matter

Before I share my keto peanut butter and chocolate brownies with you, lets talk about the quality of your ingredients.

To begin with, your peanut butter needs to be an all-natural variety. One that has zero sugar added. This will ensure that it’s low in carbs and that doesn’t throw you out of ketosis.

When using an all natural peanut butter remember to give it a good stir to ensure that all it’s fully incorporated before mixing it into your keto peanut butter swirl brownie batter.

The quality of your chocolate also matters. Personally, I’m pretty partial to Herhsey’s Dark cocoa powder.

Substitute Almond Butter For Peanut Butter Easily

But what if you can’t have peanut butter? Or you’re looking for a way to further reduce the carbs.

Not a problem…. I’ve created this recipe several times with almond butter instead of peanut butter and guess what?  Almond butter also goes amazingly with chocolate.

So, if you have a peanut allergy or don’t include legumes in your diet, don’t let that deter you from this easy keto peanut butter swirl brownies.
