Place the strawberries in a food processor or high-speed blender and purée until smooth. Reserve 2 tablespoons of the purée for the glaze.
2½ cups fresh strawberries
Pour the remaining purée into a small saucepan and simmer over medium heat for 15–20 minutes, stirring occasionally, until reduced to about ½ cup and thickened. Set aside to cool completely.
Preheat your oven to 325°F (165°C). Generously grease and flour a 12-cup Bundt pan.
In a large mixing bowl, beat the butter on high speed for 2 minutes, until creamy. Gradually add the sugar and continue beating for 4 minutes, until the mixture is pale and fluffy. Add the eggs one at a time, mixing well after each addition and scraping down the bowl as needed.
1 cup unsalted butter, 3 cups granulated sugar, 5 large eggs
Reduce the mixer speed to low. Add the flour in two batches, followed by the salt and baking soda. Mix until just combined—do not overmix.
3 cups all-purpose flour, 1 teaspoon salt, ½ teaspoon baking soda
Add the buttermilk, cooled strawberry purée, and vanilla extract. Stir until the batter is smooth and fully combined.
1 cup buttermilk, 1 teaspoon vanilla extract
Pour the batter into the prepared Bundt pan and smooth the top. Bake for 70–80 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes, then carefully invert onto a wire rack or serving platter. Allow to cool completely before glazing.
In a small bowl, whisk together the reserved 2 tablespoons of strawberry purée, powdered sugar, vanilla extract, and lemon juice until smooth and pourable.
2 tablespoons strawberry purée, 2 cups powdered sugar, 1 teaspoon vanilla extract, 1 teaspoon lemon juice
Once the cake is fully cooled, drizzle the glaze over the top. Let it set for a few minutes before slicing.
Serve and enjoy with fresh berries or a dollop of whipped cream!
