If your house is full of blondie fans, this bundt cake is going to be a home run. My husband's family goes absolutely bananas over his Nana's Butterscotch Brownies, so they were more than happy to see the same flavors show up in cake form with a vanilla glaze drizzled over the top. White chocolate and butterscotch chips together might be my favorite flavor pairing — they're basically soulmates.
Bundt cakes were actually the first cakes I ever learned to make, purely because of how simple they are. Throw everything into a pretty pan, bake, then drizzle some glaze on top as a finishing touch? Sold, every time.
This one disappears fast whenever it's on the counter.
Ingredients
For the Cake
- 3 cups all-purpose flour
- 2 1/2 cups packed light brown sugar
- 2 teaspoons baking powder
- 3/4 teaspoon salt
- 1/2 teaspoon baking soda
- 4 large eggs
- 8 oz. sour cream
- 1/2 cup unsalted butter, melted
- 1/4 cup vegetable oil
- 1 tablespoon vanilla extract
- 1 cup white chocolate chips
- 1 cup butterscotch chips
For the Glaze
- 1 cup powdered sugar
- 1 teaspoon vanilla
- 1 tablespoon butter, melted
- 2-4 tablespoons milk (depending on desired thickness)
Instructions
- 1Preheat the oven to 350 degrees. Whisk together the flour, brown sugar, baking powder, salt, and baking soda in a large bowl.
