Low Carb Peanut Butter Frosted Cupcakes

Everyone loves cupcakes! We recently made these for a dinner we were attending and not everyone there was doing keto. However, everyone loved these cupcakes! Unless you looked at the ingredients, you might not believe that these really are low carb. I think that there are three things that really make these cupcakes good:

The Right Texture

Any time we make a low carb version of anything, it seems like duplicating the texture is always the hardest part. The low carb ingredients that we use always have a great flavor, but sometimes the texture isn’t comparable to the “real thing.” That certainly isn’t the case with these cupcakes though! In our humble opinion, we really don’t think that you’ll be able to tell the difference between these and a standard cupcake! These are light, fluffy, moist, and cakey – the best adjectives in the word!

When you make the batter, you might notice that it is a little thick. That is exactly the type of batter you want! Fill your muffin cup about 2/3 of the way full with your thick batter and you’ll be off to a great start!

The Right Taste

It’s one thing for a low carb cupcake the have the right texture, but its a whole other thing for it to have the right taste! When it comes down to it, taste is what really matters, and trust me when I say that these have the right taste. I think the reason that these have such an authentic taste is because we used monk fruit to sweeten the cake. I can’t tell you enough how much of a difference monk fruit makes in a recipe. Monk fruit has absolutely no aftertaste so you won’t have to worry about any nasty chemical flavors ruining the taste of your cupcakes! All you will taste are the scrumptious flavors of cake, peanut butter, and maybe a little bit of heaven.

Cupcake Toppings

This is where these cupcakes really start to shine. The cake on its own is great, but when you top these with a delicious peanut butter frosting it takes them to a whole other level! To be honest, I don’t know why peanut butter frosting isn’t more popular than it is! Peanut butter compliments almost everything well and these cupcakes are no exception. If you really want to take these to another level, drizzle some ChocZero chocolate syrup over them. If you do, I can guarantee that these will be your new favorite dessert!
