Butterscotch Pecan Layer Cake with Praline Crunch and Sea Salt Tips, FAQ & printable recipe

Tips for success

Keep the cake chilled between each phase, because the frosting is the structure of the layers and firms as it cools. A short rest in the refrigerator makes the difference between a neat stack and a slipping one. Bring the cake out of the refrigerator about 20 minutes before serving, so the sponge softens and the frosting is pleasantly creamy rather than cold and firm.

Pour the warm butterscotch sauce gently and keep the pitcher close to the cake so the stream stays controlled. Let the sauce find its own path down the sides instead of spreading it heavily with the spatula, which can disturb the frosting. Save a little extra sauce for finishing, since the glossy coat on the outside uses more than the layers do.

Variations

• Walnut version: Swap the pecans for toasted walnut halves in the topping and on the ring. The slightly bitter flavor of walnuts pairs well with butterscotch, and the crunch stays just as satisfying on the top of the cake.
• Extra praline layer: Add a thin layer of chopped praline crumbs between two of the sponge layers before adding frosting. The extra crunch gives each slice a contrasting bite in the middle of the cake.
• Brown butter frosting: Replace the pale cream frosting with a brown butter buttercream, cooling the browned butter before whipping it with sugar. The nutty, toasty flavor deepens the butterscotch and makes the slices taste richer.
• Salted caramel finish: Drizzle a little extra warm butterscotch sauce over each slice just before serving, and finish with a few more flakes of sea salt. The extra sauce and salt sharpen the caramel flavor for guests who want more.

Storage and make-ahead

Fridge

Refrigerate the covered cake for up to three days, and let it rest 20 minutes at room temperature before serving for the best texture.

Freezer

Freezing is not recommended because the cream frosting and the glossy sauce can separate and lose their smooth finish when thawed.

Store the finished cake covered in the refrigerator, where it keeps its shape and the sauce stays glossy. Use a cake dome or loose wrap that does not touch the top, so the praline shavings and pecans stay crisp. Keep the cake away from strong-smelling foods, since cream frosting absorbs odors.

Remove it from the refrigerator 20 minutes before serving to let the sponge soften slightly. Leftover slices should be wrapped individually and refrigerated within two hours of serving, and they keep well for about three days.

You can prepare the sponge layers and the butterscotch caramel sauce a day in advance, then keep them separate and chilled until you assemble the cake. Toast and chop the pecans ahead and store them in an airtight container at room temperature.

Grate the praline on the day you decorate, since shavings can soften if they sit in a warm kitchen. Assemble, chill and coat the cake the same day you serve it so the frosting is firm and the sauce looks glossy. Following this order keeps the components fresh and makes the final decorating quick and clean.

Serving ideas

Serve the cake at cool room temperature so the frosting is creamy and the sponge is tender. Cut slices with a long knife dipped in hot water and wiped between cuts, which keeps each layer distinct and the glossy sauce neat.

Set each slice on a plate with a small spoonful of extra butterscotch sauce and a few grated praline shavings for crunch. A glass of cold milk or a cup of strong coffee pairs well with the sweetness of the butterscotch and the toasted pecans.

This cake suits a holiday table, a birthday, or a dinner party where dessert is the highlight. Because it looks dramatic with very little extra effort, it works well as a centerpiece on a cake stand.

Leave the decorated ring of pecan halves visible and keep the flaky sea salt on the side so guests can add a pinch to their own slice if they like the contrast of salt and caramel.

Butterscotch Pecan Layer Cake with Praline Crunch and Sea Salt

Prep 45 minCook 10 minRest 30 minTotal 1 h 25 minServes 12

Ingredients

• 3 vanilla sponge cake layers, store-bought or made ahead
• 3 cups pale cream frosting, such as a whipped vanilla buttercream
• 1 cup warm butterscotch caramel sauce, store-bought or made ahead
• 4 oz firm butterscotch praline pieces, for grating
• 2 tbsp packed brown sugar
• 1 cup pecan halves, toasted and chopped, plus 12 whole toasted pecan halves for the top
• flaky sea salt, to taste

Instructions

1. Roughly chop the toasted pecans with a chef's knife on the cutting board. Add the brown sugar and chop them together until the mix is coarse and sandy. Set the mixture aside for the topping.
2. Break the firm butterscotch praline pieces into smaller chunks. Grate them on a fine microplane-style grater over the board so golden curls and shavings fall onto the surface. Keep the shavings separate.
3. Place one sponge cake layer on the turntable inside the acetate ring. Spread an even, thick layer of pale cream frosting over the top, reaching the edges. Build the next layer the same way.
4. Pour the warm butterscotch caramel sauce from the metal pitcher over the frosting on each layer. Let it drip down the sides. Place a pecan half in the center of the top layer.
5. Stack the remaining sponge layers with frosting and sauce between each one. Press gently to align the layers. Refrigerate the cake for 30 minutes so the frosting firms.
6. Remove the acetate ring. Coat the whole cake with glossy butterscotch sauce, smoothing it with the offset spatula. Arrange a ring of whole toasted pecan halves along the top edge.
7. Sprinkle the chopped pecan and sugar mixture and the grated praline over the top. Finish with a pinch of flaky sea salt. Slice with a long knife dipped in hot water and serve.
