Detailed Step-by-Step Instructions
- Prepare Equipment (5 minutes)
- Preheat oven to 350°F (175°C). Line standard 12-cup muffin tin with paper liners. Gather room temperature ingredients and digital scale.
- Mix Base Ingredients (10 minutes)
- Sift flour, baking powder, and salt in medium bowl. Beat butter, sugar, and lemon zest in stand mixer at medium speed (setting 6) for 3 minutes until pale and fluffy. Scrape bowl twice during mixing.
- Complete Batter (8 minutes)
- Add eggs one at a time, beating 30 seconds each. Mix in vanilla. Alternate adding dry ingredients and milk mixture in 3 parts, mixing 15 seconds between each. Stop when just combined - do not overmix.
- Bake and Cool (30 minutes)
- Fill liners 2/3 full (about 60g batter each). Bake 18-20 minutes until toothpick comes out clean and internal temperature reaches 205°F (96°C). Cool 5 minutes in pan, then transfer to rack.
- Fill Cupcakes (15 minutes)
- Once completely cool, cut 1-inch deep, ¾-inch wide cores from centers. Fill each with 1½ teaspoons (7g) raspberry preserves. Trim and replace cake tops.
- Make Buttercream (15 minutes)
- Beat room temperature butter (65°F/18°C) for 5 minutes until very light. Add powdered sugar in 3 additions. Mix in preserves, milk, vanilla, and salt. Beat on high speed (setting 8) for 3 minutes until fluffy.
- Decorate and Finish (20 minutes)
- Transfer buttercream to piping bag with 1M tip. Pipe swirls on each cupcake, starting from outside edge. Garnish with fresh raspberry and lemon zest if desired. Refrigerate 20 minutes to set.
Storage and Make-Ahead Instructions
Unfrosted cupcakes keep 24 hours at room temperature in airtight container. Store frosted cupcakes in refrigerator up to 3 days. Bring to room temperature 30 minutes before serving. Freeze unfrosted cupcakes up to 2 months, wrapped individually in plastic then sealed in freezer bag. Thaw overnight in refrigerator.
Quality Control Checkpoints
Batter should be smooth but not overmixed. Cupcakes must spring back when touched and reach 205°F (96°C) internal temperature. Preserves should be thick enough not to seep into cake. Buttercream temperature critical - too warm causes separation, too cold prevents smooth piping. Check all expiration dates before starting.
Required Equipment List
Stand mixer with paddle and whisk attachments essential for proper texture. Standard 12-cup muffin tin with 2½-inch diameter cups. Digital scale for precise measurements. Candy thermometer to verify temperatures. Large (16-inch) piping bag with Wilton 1M star tip. Digital instant-read thermometer for testing doneness.
Common Issues and Solutions
Dense cupcakes indicate overmixed batter - fold dry ingredients gently. Sunken centers mean oven door opened too soon - wait until minute 15 to check. Curdled batter results from cold ingredients - ensure room temperature components. Separated buttercream needs 5 minutes beating at high speed. Leaking filling means too much jam - stick to 1½ teaspoons per cupcake.
Recipe Variations
Substitute blueberry preserves and lime zest for raspberry-lime version. Use orange zest and marmalade for citrus twist. Create dairy-free option with plant-based butter and milk alternatives. Add 1 teaspoon culinary lavender to batter for floral notes. Reduce sugar to ¾ cup for less sweet version. Each variation maintains same baking time and temperature.
Safety and Quality Guidelines
Check internal temperature reaches 205°F (96°C) for food safety. Discard if left at room temperature over 24 hours. Store preserves below 40°F (4°C) between uses. Sanitize all equipment before starting. Use pasteurized eggs if serving high-risk individuals. Never consume raw batter. Verify all ingredients within expiration dates.
