In a large bowl, beat the softened butter and sugar together until the mixture is smooth, light, and fluffy, this step builds the base of your cookies, so take your time with it.
Once it’s nicely creamed, mix in the egg, vanilla extract, and fresh lemon juice until everything is fully combined and the batter looks silky.
Carefully fold in the flour, lemon zest, baking powder, and baking soda, mixing just until everything is mostly combined, avoid overmixing.
If your raspberries are frozen and whole, break them into smaller bits.
Carefully fold them into the dough, just a few folds, so you keep those beautiful raspberry streaks running through.
Chill the dough in the fridge for about 20 minutes to help it firm up and reduce spreading.
Use the chill time to heat your oven to 350°F (175°C) in preparation for baking. Line a baking sheet with parchment paper.
Once the dough is ready, scoop it out and place the cookie balls on the sheet, leaving space between each one to let them spread.
Bake for 10–12 minutes, or until the edges look slightly golden and puffed.
Allow the cookies to cool slightly on the tray before placing them on a wire rack to finish cooling. Whether warm or cooled, they’re absolutely irresistible!
