Preheat your oven to 350°F and measure out all the cake ingredients.
In a large bowl, beat the butter and sugar with a hand mixer on medium speed until light and fluffy.
In a separate small bowl, whisk the 6 eggs with a blending whisk.
Add vanilla, lemon zest, and milk to the eggs, then whisk until smooth.
In another bowl, mix the flour, baking powder, and salt together.
Gradually add ⅓ of the egg mixture and ⅓ of the dry ingredients at a time to the butter and sugar mixture, mixing well after each addition.
Mix until the batter is smooth and fully combined.
Gently fold the fresh cranberries into the batter with a spatula.
Coating the Bundt Cake Pan and Baking the Cake
Using gloved hands, coat the entire inside of the bundt pan with vegetable shortening, making sure to cover every corner. I like to wear food-safe disposable gloves to keep my hands clean during this step.
Sift a light layer of flour over the shortening, then tap out any excess.
Evenly pour the cake batter into the prepared bundt pan.
Bake for 50–65 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool for 10 minutes in the pan before removing it. If removed too soon, the cake might break apart.
Once slightly cooled, flip the cake onto a cooling rack and let it rest for 1–2 hours before glazing.
Making the Easy Lemon Glaze
In a medium bowl, whisk together powdered sugar and lemon juice until smooth. That’s it—your simple lemon glaze is ready to go!
Sugaring the Cranberries
Rinse the cranberries under cold water and line a baking sheet with paper towels.
Pour ½ cup of sugar into a large mixing bowl and set it aside.
In a small saucepan, combine ¼ cup of sugar and water over medium heat.
Stir until the sugar completely dissolves.
Then, let the sugar syrup cool entirely. Dip the cranberries into the syrup, then transfer them to the paper towel-lined baking sheet.
Roll a few cranberries at a time in the reserved sugar until well coated. Let the sugared cranberries dry on the lined baking sheet before assembling the cake.
Lemon Cranberry Bundt Cake Assembly
Slice a fresh lemon into rounds, then cut each round into four wedges.
Slide a piece of parchment paper under the cooling rack holding your completely cooled cake. Slowly drizzle the lemon glaze evenly over the entire bundt cake.
Decorate the top of the cake with lemon wedges and sugared cranberries for the perfect finishing touch.
