Preheat the oven to 325°F. Prepare the bundt pan: spray with a non-stick baking spray and sprinkle flour throughout the pan. Shake to coat, and discard any excess flour.
In the bowl of a stand mixer fitted with a paddle attachement, cream the softened butter, shortening and sugar on medium speed for 5-7 minutes or until butter becomes noticeably lighter in color and fluffy.
1 cup unsalted butter, softened (16 Tbsp.), 1/2 cup shortening, room temperature, 3 cups sugar
Meanwhile, sift together the flour, baking powder and salt. Set aside.
3 cups All-Purpose Flour, 1/2 tsp. baking powder, 1 tsp. kosher salt
Decrease mixture to low and beat in the eggs, one at a time. Beat each egg just long enough for the yellow to disappear (about 30 seconds). Add in the lemon juice, lemon zest and lemon extract.
6 large eggs, room temperature, 1 1/2 Tbsp. lemon zest, 1 Tbsp. lemon extract, 2 Tbsp. lemon juice
Gradually add the flour mixture alternately with the heavy cream or milk, beginning and ending with the flour mixture. Beat just until combined after each addition.
1 cup heavy cream, room temperature (or whole milk)
Spoon batter into prepared bundt pan. Gently tap the pan 3-5 times on a work surface to release any air bubbles that may have developed. This will also insure that the batter fills every crevice of the pan.
Bake for 65-70 minutes or until a toothpick inserted near the center comes out clean. Cool for 10-15 minutes before inverting onto a wire rack. (Note: place a piece of parchment paper underneath for easy clean-up).
Make the lemon syrup: in a microwave safe bowl, combine the powdered sugar and lemon juice. Stir to combine and microwave for 1 minute. Poke holes all around the cake with a fork or toothpick and brush the syrup over the cake, letting it soak into the holes.
1/2 cup powdered sugar, 1/4 cup lemon juice
Once cake is cooled, mix the ingredients together for the glaze and spoon it over the cake, allowing it to drip down the sides. Slice and enjoy!
