                Set your oven to 350°F (175°C) and line a muffin pan with paper liners.

                Grab a medium bowl, toss in the flour, baking soda, baking powder, and salt, then give it a whisk. Put it aside for now.

                In a big bowl, beat the soft butter with sugar for about 2-3 minutes until it’s nice and fluffy. Add the eggs one at a time, then mix in the vanilla and lemon zest.

                Add the dry mixture to the wet stuff in turns, swapping with buttermilk. Start and end with the dry mix. Stir until it’s just all together.

                Scoop the batter into the prepared liners so they’re about 2/3 full.

                Pop the tray in the oven and bake for 18-20 minutes. Use a toothpick to check—they’re done when it comes out clean. Cool completely on a rack after removing them.

                Once the cupcakes cool, dig out a little from the middle with a knife or cupcake corer. Fill each hole with a mix of raspberry jam and lemon curd before popping the tops back on.

                Beat the butter until creamy, then slowly add the powdered sugar. Toss in the vanilla and gradually mix in cream until it’s nice and spreadable. Whip until fluffy.

                Spread or pipe frosting over each cupcake, then place a fresh raspberry right on top.
