These blackberry cupcakes are the most tender cupcakes! They are vanilla cupcakes that use a no calorie sweetener and are filled with a blackberry jam. They topped with a blackberry cream cheese frosting. These cupcakes are a must bake!
The Most Tender Cupcakes
These cupcakes are super moist and tender because of one ingredient. They have Allulose no calorie sweetener from Wholesome Sweeteners.
Allulose sweetener is a rare sweetener made naturally from figs, raisins, and kiwi. This sweetener is super sweet, but the best part? Zero Calories!
This sweetener is just as sweet as regular white sugar but so much better for you. When I was first recipe testing these cupcakes, I couldn't tell this was made with anything other than white sugar.
Another reason that Allulose sweetener is the best, is that it is perfect for baking. It turned these cupcakes into this incredibly tender texture. I tried making these cupcakes with regular sugar and Allulose, the one with Allulose sweetener felt a lot more moist!
After baking with it, I am sold! The only difference is you have to use slightly more of this sweetener compared to white sugar to get the right sweetness.
How To Make Vanilla Cupcakes
These vanilla cupcakes are such a staple cupcake. They have a strong vanilla flavor and they are easy to make.
- Use cake flour- Using cake flour will help getting a more tender crumb. Cake flour has less gluten than regular flour. I found cake flour at my local grocery store. Make sure you sift it!
- Beat butter and Allulose sweetener- Next, beat these together for 3 minutes. This will aerate the butter and give you a better rise with the cupcakes. It will start by being crumbly, but it quickly turns light and fluffy.
- Add sour cream and vanilla- Make sure to use full fat sour cream. The fat from the sour cream breaks down the gluten to create a more moist and tender crumb.
- Add in eggs one at time- Slowly add these in and mix until just combined before adding another one. Scrape the bowl to make sure the butter is mixed in.
- Add in dry ingredients and buttermilk- Pour these in 3 different intervals. This will make sure everything is getting mixed together well.
- Scoop- Use a cookie scoop to easily scoop the batter into the muffin tin. Fill until about ⅔rds full.
Once the muffin tin is full, bake for 15-17 minutes. Next, let the cupcakes cool completely before decorating and filling.
Easy Blackberry Jam
When I first made these cupcakes, I tried a blackberry puree in the cupcakes. The flavor of blackberries was almost non-existent! That's why I made a blackberry jam. When you bite into the cupcake, it is such a strong flavor!
To make this blackberry jam, combine blackberries, Allulose sweetener, lemon juice, salt and water. Then, heat for 8-10 minutes. Since we are only making a little to fill the cupcakes, it doesn't take long to make.
Halfway through cooking, take a potato masher or a wooden spoon to mash the blackberries.
The jam has to be completely cool before adding it into the cupcakes. I suggest making this first, or a day ahead.
Filling The Cupcakes
Use a cupcake corer or a sharp knife to cut into the cupcakes. Cut only ⅔rds down the cupcakes. Save the tops, because you will be replacing them later.
For easy filling, use a teaspoon to fill the cupcakes. Use all of the jam! Then, replace the tops.
Purple Blackberry Cream Cheese Frosting
This frosting is naturally purple which make these even better! To get this purple color, it uses blackberry puree.
The blackberry puree needs to be run through a sifter so there are no seeds in this frosting. A small container of blackberries will make ⅓ cup of puree, and we only need ¼ cup.
First, beat the butter and cream cheese together until light and fluffy. Then, add in the powdered sugar. Wholesome Sweeteners has a great organic powdered sugar that I recommend.
There is a lot of powdered sugar in this recipe. This is to create a stiffer frosting for piping on top of these cupcakes. I tried using less, and the frosting was goopy.
Next, add in the blackberry puree and salt and mix well!
For best results, place frosting in the fridge for 15 minutes to firm it up. Then, use a wooden spoon to mix until creamy before frosting the blackberry cupcakes.
How To Store The Cupcakes
These cupcakes should be stored in the fridge in an air tight container.
They will last up to 5 days in the fridge.
Freezing The Cupcakes
I don't recommend freezing the cupcakes when they are fully decorated. The frosting texture with the jam would be weird thawing from frozen.
However, you can make the cupcakes ahead of time, and freeze! Wrap each cupcake in cling wrap and store in an air tight container. Freeze up to 1 week.
To thaw, place on the counter for at least 2 hours before filling and decorating.
