For a richer lemon flavor, consider adding a teaspoon of lemon extract to the batter. Ensure the butter is properly softened for a smooth and creamy batter. If you don't have sour cream, plain Greek yogurt can be used as a substitute.
Elevate your mornings with this exquisite coffee cake, where the bright tang of lemon dances harmoniously with the creamy sweetness of white chocolate. A delightful streusel topping adds a satisfying crunch to every bite.
Preheat oven to 350 degrees F (175 degrees C). Grease and flour an 8-inch springform or cake pan, or line the bottom with parchment paper. (5 minutes)
In a small bowl, whisk together 1 cup flour, 1/4 cup white sugar, and 1/4 cup brown sugar. Stir in melted butter until crumbly. Set aside for topping. (10 minutes)
In a large bowl, cream together softened butter, 1/2 cup white sugar, and lemon zest until light and fluffy, using an electric mixer for about 3 minutes. (5 minutes)
Beat in eggs, lemon juice, baking powder, vanilla extract, salt, and cinnamon until well combined, about 3 minutes. (5 minutes)
Gradually add 2 cups flour on low speed until just combined. Mix in sour cream and milk until smooth, about 4 minutes. (8 minutes)
Fold in white chocolate chips. Pour batter into prepared pan and sprinkle evenly with the streusel topping. (2 minutes)
Bake in preheated oven until golden brown and a toothpick inserted into the center comes out clean, about 40 minutes. (40 minutes)
Cool on a wire rack for about 30 minutes before removing from pan and serving. (30 minutes)
