Ingredients
Equipment
Method
- Preheat the oven to 350°F.
- Grease a 9x13-inch baking pan.
Make the cinnamon-pecan swirl
- Stir together the brown sugar and cinnamon in a small bowl.
- Mix in the pecans.
Mix the batter
- Whisk the flour, baking powder, baking soda, and salt in a medium bowl.
- Beat the butter and granulated sugar in a large bowl with an electric mixer on medium speed until light and fluffy, about 2 minutes.
- Beat in the eggs one at a time.
- Mix in the vanilla.
- Mix in the flour mixture in three additions, alternating with the sour cream in two additions, beginning and ending with the flour mixture; mix just until combined.
Assemble and bake
- Spread half of the batter in the prepared pan.
- Sprinkle with half of the cinnamon-pecan mixture.
- Spread the remaining batter over it.
- Sprinkle with the remaining mixture.
- Bake for 32 to 38 minutes, until the cake is golden and a toothpick inserted into a cake-only spot comes out with a few moist crumbs.
- Cool in the pan for at least 15 minutes before serving.
Notes
For an even swirl, spread the batter gently so the cinnamon-pecan layers stay distinct. Refrigerate covered for up to 4 days; freezer: yes, freeze slices for up to 2 months. For a gluten-free variation, use a 1:1 gluten-free baking flour in place of the all-purpose flour.
