Blackberry Bundt Cake is a buttery, moist blackberry cake made with buttermilk, vanilla, and fresh or frozen blackberries, then finished with a simple blackberry glaze. This easy blackberry bundt cake has been tested over 10 times for the perfect tender crumb that isn’t overly sweet.
Preheat the oven to 325°F. Grease a large bundt pan with 1 tablespoons vegetable shortening and lightly flour for easy release.
In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter until light and fluffy. Cream with 2 1/2 cups sugar until well blended. Add each 4 large eggs, one at a time, until blended. Then the 2 teaspoons vanilla extract
In a separate bowl, sift or whisk together the 3 cups flour, 1 1/2 teaspoon baking powder, 1 teaspoon fine sea salt and 1/2 teaspoon baking soda .
Alternating, pour in the 3/4 cup buttermilk and dry ingredients in 3 increments until just mixed.
By hand, fold in the halved 1 1/2 cups blackberries.
Transfer the cake to the prepared baking pan, evening out the top with a spatula.
Bake for 60-70 minutes or until it passes the toothpick test for registers at 205°F using an instant read thermometer.
Allow to cool for 5-10 minutes before inverting onto a cooling rack to complete cooling. Do not wait until fully cool to remove from the cake pan or it will struggle to release.
Muddle 1/2 cup fresh blackberries in a bowl, stirring in 2 teaspoons milk . Optionally, strain the glaze to remove blackberry seeds. Whisk in 1-2 cups powdered sugar , adding slowly, until a drizzlable consistency.
When the cake has cooled, drizzle with the icing.
