Gluten-Free Pumpkin Layer Cake with Brown Butter Frosting

Gluten-free pumpkin layer cake with brown butter frosting and a ring of candied pecans

This is the project cake. Two layers, brown butter in both the cake and the frosting, a skillet of candied pecans and pepitas, and crystallized ginger through the topping.

It takes an afternoon and it is the one you make when the occasion warrants it.

Built on Pamela's Bread Mix, which gives the crumb enough structure to hold two layers without crumbling.

So good, no one will guess it is gluten-free, the way Pamela's has done it since 1988.

Brown Butter Is the Whole Point

Browning butter means cooking it past melting until the milk solids toast and it turns nutty and golden. It takes 5 to 10 minutes and it changes the flavor of everything it touches.

Use a heavy saucepan and swirl it occasionally. If it foams, spoon most of the foam off; the rest subsides as it browns.

Pour it into a bowl and leave the brown bits in the bottom of the pan. Those bits are bitter rather than nutty.

The recipe divides it two ways: three quarters of a cup for the cake, and half a cup plus two tablespoons for the frosting. The frosting portion goes into the refrigerator to solidify while you make everything else, since it needs to be solid to beat properly.

The mix this is built on Pamela's Gluten-Free Bread Mix Dairy-free, egg-free, and nut-free. Yeast packet included in the bag. GFCO-certified.

These Layers Are Fragile

A gluten-free cake has nothing holding it together while it is hot.

Let the layers cool in the pans a full 15 minutes before turning them out. Rushing this is how a layer breaks in half.

Line the pan bottoms with parchment rounds and spray twice, before and after the paper goes in. Or use pans with removable bottoms.

The cake is done when it starts to pull away from the sides and a toothpick comes out clean, about 38 to 42 minutes.

Assembling It

Three quarters of a cup of frosting on the first layer, then three quarters of a cup of the nut mixture over it, then the second layer.

Frost the top and sides with the rest, then arrange the remaining nut topping in a ring about an inch and a half in from the edge. That ring is what makes it look finished.

It can be covered with a cake dome and refrigerated up to 2 days, and it is best served at room temperature.

Directions

  1. Make the brown butter. Melt the 1 cup plus 6 tablespoons of butter in a heavy 1-quart saucepan over medium heat. Cook, swirling occasionally, until it turns nutty golden brown, 5 to 10 minutes. Spoon off most of the foam if it rises. Pour into a bowl, leaving the brown bits in the pan.
  2. Leaving any brown bits behind, measure out 3/4 cup for the cake and 1/2 cup plus 2 tablespoons for the frosting into two bowls. Refrigerate the frosting portion so it solidifies while you work.
  3. Make the topping. Melt the 1 1/2 tablespoons of butter in a heavy 10 to 12-inch nonstick skillet over medium heat. Add the pecans and pepitas and cook until the pecans brown slightly and the pepitas begin to pop, 2 to 3 minutes. Sprinkle in the brown sugar and salt and stir until the sugar melts and coats the nuts, about 2 minutes. Stir in the crystallized ginger. Remove from heat and let cool in the skillet.
  4. Heat the oven to 350 degrees F with a rack in the center. Spray two 9-inch round cake pans, line the bottoms with parchment rounds, and spray again. Or grease and flour two 9-inch pans with removable bottoms.
  5. Set the yeast packet aside, it is not used here. In a medium bowl, whisk together the Bread Mix, baking soda, baking powder, cinnamon, ground ginger, salt, and cloves.
  6. In a large bowl, whisk the pumpkin puree with the oil if using fresh, the granulated sugar, brown sugar, eggs, and buttermilk until very well blended. With a rubber spatula, stir in the dry mixture until just combined. Gently whisk in the 3/4 cup of cooled brown butter until fully incorporated.
  7. Divide the batter evenly between the pans. Bake 38 to 42 minutes, until the cake starts to pull away from the sides and a toothpick comes out clean.
  8. Cool the layers in the pans 15 minutes before turning out onto a rack to cool completely. They are very tender, so do not rush this.
  9. Make the frosting. With a stand mixer and paddle attachment, beat the solid brown butter, cream cheese, and brown sugar on medium-high until the sugar dissolves and the frosting lightens, 2 to 3 minutes. Gradually beat in the powdered sugar until smooth and fluffy, 1 to 2 minutes.
  10. Assemble. Put one layer on a cake plate and spread 3/4 cup of frosting over it. Sprinkle 3/4 cup of the nut mixture over the frosting and top with the second layer. Frost the top and sides with the rest, then arrange the remaining topping in a ring about 1 1/2 inches in from the edge.

Recipe Tips & Notes

The Yeast Packet

Pamela's Bread Mix comes with a yeast packet in the bag. This recipe does not use it.

Set the packet aside before you measure. The yeast has no role here, since the batter goes straight into the oven with chemical leavening doing the lifting, and it is easy to tip in by accident when emptying the bag.

Save it for a loaf of bread, or discard it.

Make-Ahead and Storing

The assembled, frosted cake can be covered with a cake dome and refrigerated up to 2 days. It is best served at room temperature, so take it out about an hour before.

The layers can be baked a day ahead, cooled completely, wrapped tightly, and left at room temperature.

The brown butter can be made up to a week ahead and refrigerated. Let the cake portion come back to pourable before using it.

The nut topping keeps a week in an airtight container at room temperature.

The layers freeze up to 2 months, unfrosted and well wrapped. Thaw at room temperature before assembling.

Ways to Change It Up

Skip the crystallized ginger if you cannot find it. Add a quarter teaspoon of ground ginger to the topping instead.

Walnuts in place of pecans at the same two thirds of a cup.

A single-layer version. Bake the whole batch in a 9x13 and frost the top only. Start checking at 35 minutes.

Add a half teaspoon of flaky salt over the frosting before the nut ring goes on.

Fresh pumpkin puree works, which is why the oil is listed as conditional. Drain it in a sieve first, since it is wetter than canned.

What This Contains

This recipe contains milk and egg.

The butter, buttermilk, and cream cheese are dairy. The two eggs are structural.

The pecans and pepitas are tree nuts and seeds. Pepitas are pumpkin seeds rather than tree nuts, but the pecans are, so this is not a nut-free recipe.

Pamela's Bread Mix itself is dairy-free, egg-free, and nut-free, so the allergens come entirely from what you add.

Everything from Pamela's is certified by the Gluten-Free Certification Organization and made in a certified gluten-free, peanut-free facility.

Recipe FAQs

Melt it in a heavy saucepan over medium heat and keep cooking past melting until the milk solids toast and it turns nutty golden brown, 5 to 10 minutes. Swirl occasionally and spoon off most of the foam if it rises. Pour it out, leaving the dark bits in the pan, since those are bitter.

They have nothing holding them together while hot. Let them cool in the pans a full 15 minutes before turning out, line the bottoms with parchment rounds, and spray both before and after the paper goes in.

Yes. Bake the layers a day ahead, cool completely, and wrap tightly at room temperature. The assembled frosted cake keeps 2 days refrigerated under a dome, and it is best served at room temperature, so take it out about an hour before.

No. Set it aside before you measure. The cake is leavened with baking soda and baking powder, and the yeast has no role. It is easy to tip in by accident when emptying the bag.

Yes, which is why the recipe lists 2 teaspoons of oil as conditional. Fresh puree is wetter and less rich than canned, so drain it in a sieve first and add the oil to compensate.
