Chocolate Buttercream Vanilla Cupcakes with Strawberry Filling

This flavor combination was brought to you by my very pregnant friend who wanted these cupcakes for her birthday, last month. She must have changed her mind at least ten times, about her birthday treat. She finally settled on the vanilla cupcakes with strawberry filling and chocolate buttercream frosting. I made her chocolate buttercream frosting for her cake last year and she fell in love. This frosting is all she talks about, so I knew she would want it again. I also made her a little extra frosting and she had it with some strawberries….after she polished off some cupcakes. Hehe!

The cupcakes came out pretty good. Although, I did try a new recipe for the cupcakes themselves. Why in the world would I try a new recipe when I am making them for someone else? I just don’t know. I used a recipe that had sour cream in it…I can do without it next time. The cupcakes were soft and moist but I really like my regular recipe better.

1 1/2 cups all-purpose flour
3/4 cup granulated sugar
1 1/2 tsp baking powder
1/2 tsp salt
8 tbs unsalted butter, room temperature
1/2 cup sour cream
1 large egg, room temperature
2 large egg yolks, room temperature
1 1/2 teaspoons vanilla extract
2 tbs whole milk

16 oz butter
2-3 cups of powder sugar
3 egg yolks
5 oz dark semi-sweet chocolate, melted and cooled to room temperature

Strawberry Filling:
2 1/2 cups of chopped strawberries
2 tbs lemon juice
1 cup sugar (I don’t like too much sugar but feel free to add more, if you like)


*I made the strawberry jam a day before because I was making my own. If you are using store-bought jam, you are good to go for the cupcakes, so skip this part.

Strawberry Filling/Jam:

1. Chop the strawberries and place them in a pot. Add the lemon juice and sugar. Set the heat on medium, stir and cook for about 15-20 minutes. Lower the heat to medium low and cook, stirring occasionally, for another 20-25 minutes.

2. Drain off about a third of the liquid. (You can use the strawberry liquid on top of the ice cream of in a milk) Place the cooked berries in a blender and puree. Refrigerate until you are ready to use it.


~Preheat the oven to 350 and grease a 12-cup muffin pan.

1. Beat the butter and sugar until light and smooth.

2. Add the egg and egg yolks, one at a time.

3. Add the sour cream, milk and vanilla extract.

4. Add the flour, salt and baking powder. Mix until all ingredients completely combined.

5. Divide the batter between the muffin cups (filling the cups about 2/3 full) and bake for 20 minutes. Do a toothpick test to make sure the cupcakes are done.

6. Fill a pastry bag with the strawberry jam filling. Use a long thin decorating tip. Insert the tip into the cooked cupcakes while they are still hot and squeeze some of the filling into them.

Chocolate Buttercream Frosting:

1. Warm the chocolate in a double boiler or in the microwave until melted and allow to cool slightly.

2. Beat the butter until it is fluffy (about 3-5 minutes) and then add in the icing sugar and the egg yolk alternately, beating after each addition.

3. The mixture should be very fluffy.

4. With the mixer still running on medium low, gradually drizzle in the melted chocolate.

5. Transfer the frosting to the pastry bag and frost the cupcakes.
