Keto Vanilla Cupcakes in a Jar (With Homemade Buttercream)

By Bree

At first glance, this classic vanilla cupcakes in a jar recipe looks like it’s quite a fancy dessert indeed. There’s no need to worry if you’re a baking novice though, as everyone who knows me knows how much I love simplicity when it comes to my dessert recipes. Despite the fancy final appearance, this cupcake recipe is deceptively easy to prepare. The vanilla cupcakes are gluten and sugar-free and the homemade buttercream frosting is unbelievably delicious — this dessert is definitely a real keto style fat bomb! And unlike the cupcakes that you’ll find in the bakery section at the grocery store, there’s no need to feel guilty for indulging in these cupcakes. As a matter of fact, this dessert could be a rather useful recipe for helping to keep those unwanted pounds off!

Cupcakes Are Even Better in a Jar

Instead of using refined wheat flour to make your cupcake batter, you’ll be opting for coconut flour and baking powder instead. Along with almond flour, I always turn to coconut flour as my go-to keto baking flour because it’s such a nutrient-dense option that is perfect for my keto dieting needs. It’s a rich source of dietary fiber and it’s full of medium chain triglyceride saturated fats, my absolute favorite kind of fatty acid.

It’s unfortunate that in this day and age there are still so many people out there who shy away from saturated fats in all varieties, when the most recent research shows that it’s an essential fat to include in your diet. In fact, medium chain triglyceride fatty acids have been shown to be incredibly beneficial when it comes to helping people achieve their weight loss goals without negatively impacting metabolic risk factors.

As with our other great keto cake recipes, these cupcakes will also require you to mix together some high quality fat ingredients to make a “wet” mix to pair with the coconut flour mixture. You’ll need to beat six large eggs together with a zero calorie sweetener like Stevia for a few minutes, and then reduce the speed in order to add in some unsweetened almond milk, vanilla extract, and melted butter. I strongly recommend that you use grass-fed butter in this recipe, and all of our keto recipes for that matter. It’s been proven to possess higher concentrations of omega-3 fatty acids and disease-fighting antioxidants when compared with regular types of butter. (2)

After combining your “wet” mixture with the coconut flour, scoop the batter into your prepared muffin cups and bake them for about 20 minutes. While they’re baking, you can make your homemade buttercream frosting by mixing more grass-fed butter and Stevia until they form a smooth and creamy mixture, and then adding in some vanilla extract and softened cream cheese. To finish the recipe off and give this dessert it’s fancy layered appearance in a jar, simply follow the directions listed below for cutting the cupcakes into horizontal pieces and layering them in with the frosting. You can then place them in the refrigerator until you’re ready to enjoy them.
