Ingredients
Method
Preparation
- Preheat your oven to 350 degrees F (175 degrees C). Line a 12-cup cupcake pan with paper baking cups.
- In a large bowl, mix the softened butter and granulated sugar together until light and fluffy, about 5 minutes.
- Stir in the egg whites, one at a time, blending well after each addition.
- Stir in the flour, baking powder, and vanilla until just combined. Add milk as needed until the batter is similar in consistency to pancake batter.
- Spoon the batter into the prepared cups, filling each about two-thirds full.
Baking
- Bake for 18 to 20 minutes, or until the tops spring back when lightly pressed. A toothpick inserted into the center should come out clean.
- Allow the cupcakes to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.
Filling and Frosting
- For the filling, place the raspberry jam into a piping bag fitted with a 230 tip. Press the tip into the cooled cupcake and fill it with jam until you feel slight resistance.
- For the frosting, mix the softened butter, cream cheese, sifted confectioners sugar, and vanilla extract in a stand mixer until creamy and well-blended, about 3-5 minutes.
- Pipe the frosting over the filled cupcakes, and chill until ready to serve.
Notes
For best results, bring dairy ingredients to room temperature before baking. Store in an airtight container at room temperature for up to 2 days, in the fridge for about a week, or freeze for up to 3 months.
