One of the biggest challenges when baking on a keto or low-carb lifestyle is finding the right sweetener. We all want that perfect balance of sweetness, texture, and flavor without spiking blood sugar. But with so many options—erythritol, monk fruit, allulose, stevia, blends—it can feel overwhelming to know which one works best, especially in baking.
As someone who lives with diabetes and bakes regularly for my family here in the Dominican Republic, I’ve had plenty of trial-and-error moments with keto-friendly sweeteners. From collapsed cakes to cookies that turned out more like puddles, I’ve seen it all! But over time, I’ve discovered which sweeteners perform well in different baked goods and how to tweak recipes when substitutions are necessary. In this guide, I’ll share everything I’ve learned so you can make your low-carb baked goods taste just as good as traditional ones.
Erythritol: The Most Popular Keto Sweetener for Baking
Erythritol is one of the most widely used keto sweeteners, and for good reason. It’s a sugar alcohol that’s about 70% as sweet as sugar, with almost zero calories and a glycemic index of zero. The best part? It mimics sugar’s texture really well, making it great for cookies, muffins, and even cakes.
The downside is that erythritol can crystallize after cooling, leading to a slightly crunchy texture in things like cheesecake or frostings. It can also cause a cooling sensation on the tongue, which some people don’t love. Personally, I’ve found that when I make my Grammie Shirley’s ginger snaps using erythritol, the cookies have a nice crunch that reminds me of her original recipe—though I do warn the kids about the cool aftertaste!
Here in the Dominican Republic, erythritol isn’t always easy to find, so I stock up whenever I can. If I run out, I sometimes use a blend of stevia and erythritol, which gives a closer taste to sugar without as much crystallization.
Monk Fruit Sweetener: Sweet Without the Aftertaste
Monk fruit is another excellent keto-friendly sweetener, and it’s one of my personal favorites for baking. Pure monk fruit extract is incredibly potent, so you’ll usually find it blended with erythritol or allulose to balance the sweetness.
The great thing about monk fruit blends is that they don’t usually have the cooling effect of erythritol alone, and they bring a clean, sugar-like taste. I love using monk fruit-erythritol blends when baking muffins for my kids because the sweetness tastes familiar to them—no complaints about “weird flavors.”
When Sarah makes her famous auyama squash bread (a local pumpkin-like squash we get fresh from the market), monk fruit blends give it the perfect moist sweetness without spiking my blood sugar. The bread stays soft for days, even in our humid climate, as long as we store it properly.
Allulose: The Closest Thing to Real Sugar in Baking

Allulose is a newer sweetener that has been getting a lot of attention in the keto world, and for good reason—it caramelizes and browns just like sugar, making it fantastic for cookies, brownies, and sauces. It’s about 70% as sweet as sugar, with almost no calories and a very low impact on blood sugar.
The texture is what makes allulose stand out. Unlike erythritol, it doesn’t crystallize after baking, so your cheesecakes stay creamy and your brownies stay fudgy. I’ve used allulose in my low-carb cheesecake, and it was honestly the closest thing to my Grammie Shirley’s original version I’ve ever made.
The only catch? Allulose can be expensive and isn’t always available here in the Dominican Republic. When I do get my hands on it, I save it for special desserts, like birthday cakes or group gatherings in our ministry work—those times when I really want to impress without anyone knowing it’s low-carb.
Stevia: A Good Backup, But Not Always Great for Baking
Stevia is one of the oldest natural sugar substitutes, but it doesn’t always shine in baking. Pure stevia extract is extremely sweet, and it can have a bitter aftertaste if used on its own. That said, it works well in combination with other sweeteners, especially erythritol.
For example, when I’m making a crock pot dessert like a low-carb apple crisp (yes, I use chayote squash instead of apples—budget-friendly and diabetic-friendly!), I’ll sometimes add a little stevia to bump up the sweetness without adding bulk. It’s not my go-to for cookies or cakes, but it has its place.
When baking in humid conditions like we have here, stevia’s lack of bulk actually helps since it doesn’t clump as much. Still, I wouldn’t rely on it as my main sweetener for baked goods.
Best Keto Sweetener Blends for Foolproof Baking
While each sweetener has its strengths and weaknesses, the truth is that blends often give the best results. That’s why many keto bakers—including me—end up keeping multiple sweeteners in the pantry.
Some of my favorite blends:
Monk fruit + erythritol – for muffins, quick breads, and cookies.
Allulose + monk fruit – for cheesecakes, brownies, and caramel-based recipes.
Erythritol + stevia – for frostings and icings where bulk matters, but bitterness can be balanced.
Blends help smooth out the cooling effects, bitterness, or crystallization problems that single sweeteners sometimes have. When I bake for larger ministry gatherings, I often rely on these blends so I don’t have to worry about a cake collapsing or cookies turning grainy.
One practical tip: humidity in the Dominican Republic can cause clumping in powdered sweeteners. I always store mine in airtight containers with a little packet of silica gel (saved from vitamin bottles) to keep them dry. That way, when inspiration strikes, I’m ready to bake without frustration.
Conclusion: Which Sweetener Should You Choose?
So, which keto sweetener is best for baking? The answer really depends on what you’re making:
For cookies and quick breads: erythritol or monk fruit blends.
For cheesecakes and brownies: allulose or allulose blends.
For frostings or recipes needing bulk: erythritol or erythritol + stevia.
For everyday baking: monk fruit blends are a reliable all-rounder.
If you’re just starting out, I recommend picking up a monk fruit-erythritol blend. It’s versatile, widely available, and tastes the most like sugar. From there, experiment with allulose when you can find it.
At the end of the day, keto baking is about making recipes that taste good, fit your lifestyle, and bring joy to your table—whether you’re making a special dessert for your kids, a cake for a ministry potluck, or just a batch of cookies to enjoy with coffee.
