Use High-Quality Butter Opt for unsalted, high-fat butter (82% or higher) for the best rich and tender texture. Let it soften at room temperature before mixing for a smooth dough.
Chill the Dough Refrigerate the dough for at least 30 minutes before baking. This prevents spreading and helps maintain a delicate, crumbly texture.
Choose a Good Raspberry Jam Use high-quality, thick raspberry jam or preserves with real fruit pieces. Avoid overly watery jams, as they can make the cookies soggy.
Incorporate Almond Flour Replace a portion of all-purpose flour with almond flour for an extra buttery, melt-in-your-mouth texture and a subtle nutty flavor.
Don’t Overmix the Dough Mix just until the ingredients are combined. Overworking the dough can lead to tough cookies instead of a light, crumbly texture.
Create the Perfect Crumble Topping Mix cold butter, flour, sugar, and a pinch of salt with your fingertips until crumbly. This ensures a crisp, buttery topping that contrasts with the soft jam.
Bake Until Lightly Golden Bake at 350°F (175°C) until the edges are slightly golden but not too brown. This keeps the cookies tender while ensuring a crispy crumble top.
