This single layer brown butter cake is tender, soft and bursting with flavor. It's a simple brown butter cake topped with a brown butter and cream cheese frosting.
Start by browning 1 cup of salted butter that will be used for both the cake and the frosting. You'll melt two sticks of butter in a medium saucepan, and then continue to cook past the point of boiling. You will do this over medium heat, past the point of the butter foaming, until it turns a nice golden brown, and has a nutty smell. Make sure you are stirring and watching it, because it will turn from perfectly brown to burnt fairly quickly. Once finished browning, pour all of it into a bowl and allow to cool completely. If you want to rush the process you can stick it in a fridge or freezer for 10-15 minutes.
To make the cake:
Preheat the oven to 325 F, and spray and line an 8 or 9 inch round or square baking pan with parchment paper.
Measure out ¼ cup of the browned butter into a medium bowl fitted with a paddle attachment. Cream butter and sugar together until light and fluffy, about 2 minutes. Add oil, eggs and vanilla and beat again for another 2 minutes.
In a small bowl whisk together flour, baking powder, and salt.
Add the dry ingredients, alternating with the buttermilk, in three parts, starting and ending with the dry ingredients.
Pour the batter into prepared baking pan.
Bake for about 26-32 minutes or until a light golden brown around the edges, and a toothpick comes out clean from the middle. Set aside to allow to cool.
To make the frosting:
In a medium size bowl mix together the rest of the browned butter (which should be about ½ cup) and the cream cheese until smooth.
Add in the salt, vanilla and powdered sugar and beat until smooth. Add in a little whipping cream or milk if needed to reach desired consistency.
Top cake with frosting. Cut and serve.
Notes
Once you brown the butter you will lose volume/moisture which is why you start with 1 cup of butter and end up with about ¾ cup. Cakes will have the best results if made with room temperature ingredients. I like to pull my eggs, milk, cream cheese and butter out of the fridge an hour or two before I start baking. This cake can also be made in a 9x13 pan for a thinner cake. If doing that I would bake it for 22-26 minutes. OR, double the recipe and bake on a cookie sheet to serve a crowd, or two round cake pans for a layered cake.I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
