Preheat oven to 350°F and spray a 10-cup Bundt pan generously with nonstick spray. Whisk together flour, almond flour, baking powder, baking soda, and salt in a medium bowl; reserve 1 tablespoon of the flour mixture to toss with the raspberries.
Beat butter and C&H® Granulated Sugar in a large mixing bowl on medium speed until light and fluffy. Beat in lemon zest and almond extract. Reduce speed to low and add eggs one at a time. Beat in flour mixture in three additions, alternating with buttermilk mixture (begin and end with flour mixture), just until incorporated. Toss raspberries with reserved flour mixture and gently fold into batter.
Spoon batter into prepared Bundt pan and smooth with an offset spatula. Tap pan sharply to reduce air bubbles.
Bake for 40 to 45 minutes, until cake is golden, springs back to the touch, and a tester inserted in the center comes out clean or with a few crumbs attached. Cool in pan on a wire rack for 10 minutes; carefully invert onto rack and cool completely.
For the glaze, whisk together melted butter, salt, lemon zest, almond extract, C&H® Powdered Sugar, and milk in a small bowl. Drizzle glaze over cake and let set before serving.
Serve cake topped with fresh raspberries and lemon slices.
