Preheat your oven: Set your oven to 350℉ (175℃) and prepare a jumbo muffin tin by lightly greasing it or using muffin liners to prevent sticking.
Mix the butters and sugars: In a large mixing bowl, combine 1 cup of softened unsalted butter, 1/4 cup of granulated sugar, 1/3 cup of powdered sugar, 1 teaspoon of vanilla extract, and 1 teaspoon of almond extract. Beat the mixture with an electric mixer for 1-2 minutes until it's fluffy and creamy.
Add the dry ingredients: Gradually incorporate 2 1/4 cups of all-purpose flour and 1/4 teaspoon of kosher salt into the wet mixture. Mix gently until the dough resembles coarse crumbs, being careful not to overwork it.
Form the crust: Scoop 1/4 cup of dough into each muffin well of the prepared tin. Press the dough lightly into the bottom and up the sides to form a base.
Add raspberry jam: Spoon 1/2 cup of seedless raspberry jam into each crust, adding about 1/2 to 1 tablespoon depending on preference.
Top with remaining dough: Crumble the remaining dough over the raspberry jam, covering it generously.
Bake: Place the muffin tin in the preheated oven and bake for 18-22 minutes, or until the tops are lightly browned and the jam is bubbly.
Cool and serve: Remove the muffin tin from the oven and allow the Raspberry Crumble Delights to cool in the tin for about 10 minutes. Carefully release them and transfer to a wire rack to cool completely before serving.
