Instructions
Make the Caramel Pecan Topping
Melt and Dissolve: In a saucepan over medium-low heat, combine the brown sugar, kosher salt, butter, honey, and corn syrup. Stir frequently with a wooden spoon until the butter melts and the sugar completely dissolves. Remove from heat.
Assemble the Pan: Pour the hot caramel straight into the bottom of a 9-inch round cake pan lined with parchment paper, then scatter the chopped pecans evenly across the surface. Set aside.
Make the Cinnamon Cake Batter
Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, granulated sugar, brown sugar, cinnamon, and vanilla extract with an electric hand mixer for 2 to 3 minutes until light and creamy.
Add Eggs: Beat in the eggs one at a time, mixing well after each addition.
Alternate Dry and Wet: Add the baking powder, baking soda, half of the flour, and half of the buttermilk. Mix on low just until combined, then stir in the remaining flour and buttermilk until smooth.
Assemble and Bake
Layer: Gently spread the cake batter over the pecan caramel layer, smoothing the top with a spatula.
Bake: Bake at 180C (350F) for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean.
Invert: Let the cake cool in the pan for 10 to 12 minutes. Place your serving plate over the pan and carefully flip it upside down. Peel away the parchment paper and let it cool completely before slicing.
Notes
Room Temperature Ingredients: Ensure your butter, eggs, and buttermilk are at true room temperature before mixing. This allows the ingredients to emulsify seamlessly, creating an even, tender crumb.
Timing the Inversion: Do not let the cake cool completely in the pan. Invert it onto your serving plate while it is still warm (10 to 12 minutes after coming out of the oven) so the caramel topping stays glossy and pliable.
Toasting Pecans: For maximum depth of flavor, use pre-toasted pecans. If your pecans are raw, toast them in a dry skillet over medium heat for 3 to 5 minutes until fragrant before chopping.
Storage: Cover and store the cake at room temperature for up to 3 days, or refrigerate for up to 5 days. Bring to room temperature or warm slightly before serving.
