Preheat oven to 350ºF (180°C).
Grease a 10 to 12-inch bundt cake pan (26cm) with 2 tablespoons shortening, making sure every nook, cranny and angle is covered. Dust with flour, shaking off excess. Reserve.
Sift 2 ¼ cups all-purpose flour, 1 teaspoon baking powder and ¼ teaspoon salt. Set aside.
In a large mixing bowl, beat the 1 cup butter until creamy. You can use an electric hand mixer or a stand mixer.
Slowly add 1 ⅓ cup white sugar and beat for 3 minutes.
Add 4 eggs one at a time, beating well after each addition.
Add the1 tablespoon lemon zest, 1 tablespoon lemon juice and ½ teaspoon vanilla extract.
Beginning and ending with sifted dry ingredients, add them in 3 parts alternating with ½ cup milk in 2 parts.
Fold in 2 cups raspberries with a spatula carefully so as not to crush them.
Pour batter into prepared pan, spreading evenly.
Bake for about 50 minutes or until a cake tester or toothpick comes out clean. Depending on the type of pan and oven you use, it might take more. So always check and take baking times given in a recipe as a reference.
Let cool for 10-15 minutes and carefully invert onto a wire rack. Cool completely before glazing.
Pour the raspberry lemon glaze slowly, letting it drip down the sides. Let it dry before slicing and serving.
