HOW TO MAKE STRAWBERRY-FILLED CUPCAKES
Prepare the filling:
- Make a slurry: In a small bowl or cup mix the cornstarch with the water until completely dissolved and the water is cloudy.
- Combine the ingredients: In a small pot over low-medium heat- combine the diced strawberries, the sugar, the cornstarch mixture, and vanilla.
- Cook and cool: Stir and bring to a boil. Lower to a simmer and cook for 5 minutes until the strawberries thicken up. Let the mixture cool completely.
Prepare the cupcakes:
- Prepare for baking: Preheat the oven to 350F and line a muffin tin with 12 cupcake liners. Set aside.
- Combine the dry ingredients: In a medium-sized bowl combine the cake flour, baking powder, baking soda, and kosher salt. Whisk until combined.
- Cream the butter and sugar: In the bowl of a hand mixer or stand mixer fitted with the paddle attachment cream the butter for 1 minute on medium speed. Scrape down the bowl and add sugar. Mix on medium speed for 2 minutes until light and fluffy.
- Add the eggs and vanilla: Scrape down the bowl and add the egg, egg whites, and vanilla extract. Mix for 1 minute on medium speed.
- Assemble the cupcake batter: Add in 1/3rd of the dry ingredients, then half of the buttermilk, and alternate, starting and ending with the dry ingredients. Mix only until combined. Do not overmix.
- Distribute and bake: Using a 3 tbsp cookie scoop, scoop the batter into the muffin liners ¾ of the way full. Bake for 20 minutes or until the centers set. Cool the cupcakes completely.
HOW TO FILL CUPCAKES
- Before filling, make sure the cupcakes are completely cooled.
- Using a cupcake corer or a small pairing knife, cut a small hole in the middle of the cupcake, making sure not to reach the bottom of the cupcake You dont want the filling to fall out! Eat or discard the top.
- Add 1-2 tsp of cooled strawberry filling to the cupcake then frost right on top!
Frosting the cupcakes
For this recipe we used classic American vanilla buttercream frosting and garnished it with crushed freeze dried strawberries. If you want to go full on strawberry you can top these with my fluffy strawberry frosting or ever a tangy strawberry cream cheese frosting.
I used a large star tip and a piping bag to pipe the frosting right on top of the cupcakes.
This recipe makes exactly 12 cupcakes and can be easily doubled.
TIPS FOR RECIPE SUCCESS
- Make sure your ingredients are at room temperature. Room temperature ingredients mix together much better and produce a more consistent cupcake. Learn how to soften butter quickly.
- Don’t overmix the cupcake batter. Mix only until combined so you don’t end up with tough cupcakes.
- Cook the strawberry filling until thickened. This will help it stay in the cupcakes and not run out when you take a bite.
- Let the strawberry filling cool completely before adding it to the cupcakes. Otherwise, the heat will cook the cupcakes and they will become dense.
- Use a small cookie scoop to portion out the batter. This will help ensure that all the cupcakes are uniform in size and bake evenly.
STORAGE AND FREEZING
To store frosted cupcakes: Strawberry cupcakes are best stored in an airtight container in the fridge for up to 4 days as they have a fresh fruit filling. Let them come to room temperature before serving. The strawberry filling can be made 5 days in advance if stored in a proper airtight container.
To store unfrosted cupcakes: Strawberry cupcakes without frosting can be stored at room temperature in an airtight container for up to 72 hours.
To freeze: Strawberry cupcakes freeze well for up to two months. I recommend freezing them unfrosted and then thawing and frosting when you’re ready to serve them. To properly freeze, place them in a freezer-safe container or bag for up to three months. When ready to serve, remove them from the fridge and let them thaw overnight on the counter before frosting.
Can I use frozen strawberries to make the filling?
It’s best to use fresh strawberries because frozen ones can make the filling watery which will make the cupcakes soggy.
Can I use a different kind of fruit for the filling?
Yes! This recipe would also be delicious with raspberries, blueberries, or blackberries.
