This soft, tender maple layer cake is filled with lovely maple flavor and topped with rich brown butter cream cheese frosting. A finishing touch of toasted pecans makes it a beautiful dessert for holidays and special occasions.
Preheat the oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.
Whisk together the flour, baking powder, baking soda, and salt. Set aside.
Using an electric mixer on medium speed, beat the butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Mix in the vanilla and maple extracts.
In a small bowl, combine the sour cream, maple syrup, and buttermilk.
With the mixer on low speed, add the flour mixture to the batter in 3 portions, alternating with 2 portions of the sour cream mixture. Mix just until combined.
Divide the batter evenly between the pans, and smooth the tops.
Bake 28 to 34 minutes, or until a pick inserted into the center comes out clean.
Cool the cakes in the pans for 15 minutes. Then remove them from the pans to cool completely on a wire rack.
To make the frosting:
Melt the butter in a saucepan over medium heat. Continue cooking, stirring frequently, until the milk solids turn golden brown and the butter smells nutty.
Remove from the heat and transfer to a heatproof bowl. Cool until thickened and spreadable but still soft (similar to softened butter).
You can refrigerate to speed this along, but be sure to stir it occasionally.
Beat the browned butter and cream cheese until smooth.
Mix in the maple syrup, both extracts, and the salt.
Gradually add the confectioners’ sugar (start with the lesser amount) and mix until fluffy. Add cream (or milk) if needed to make a spreadable consistency. Or add more sugar if needed for a thicker, sweeter frosting.
To assemble:
Place one cooled cake layer on a serving plate, and frost the top of the cake. Add the second layer, and frost the top and sides.
If necessary, level the cake layers before frosting.
Press toasted pecans onto the sides and/or scatter over the top.
Notes
Maple syrup: Use pure maple syrup, not pancake syrup, for the best flavor.
Maple extract: This helps give the cake and frosting their distinct maple flavor. I don't recommend omitting it.
Brown butter: Let the browned butter cool until thickened and spreadable, similar to softened butter, before making the frosting. If it's too warm or liquid, the frosting may be too soft.
Pecans: The toasted pecans are optional. Use chopped pecans, pecan halves, or a combination.
Storage: Store the frosted cake covered in the refrigerator up to 4 days. Let it sit at room temperature briefly before serving.
