Butterscotch Pecan Layer Cake with Brown Butter Frosting Tips, FAQ & printable recipe

Tips for success

To get clean, even slices, use a long, sharp knife and wipe it with a damp paper towel between cuts. Dip the knife in hot water and dry it before slicing for the cleanest edges.

For the best flavor, let the cake sit at room temperature for about 30 minutes before serving. This allows the frosting to soften and the butterscotch sauce to become slightly more fluid, making the cake easier to slice and more enjoyable to eat.

If you are making the cake ahead of time, assemble it without the butterscotch sauce and pecans, and refrigerate. Add the sauce and pecans just before serving to keep the crunch. The chocolate curls can be made a day in advance and stored in an airtight container at room temperature. They will stay crisp and beautiful.

Variations

• Chocolate Butterscotch Cake: Use chocolate cake layers instead of butterscotch for a richer flavor. The butterscotch sauce and pecans will still shine, and the chocolate adds a deep contrast.
• Salted Caramel Version: Substitute caramel sauce for the butterscotch sauce and add a little extra flaky sea salt. The salted caramel pairs beautifully with the pecans and chocolate curls.
• Gluten-Free Option: Use gluten-free cake layers and ensure the butterscotch sauce is gluten-free. The rest of the ingredients are naturally gluten-free.
• Bourbon Butterscotch: Add 2 tablespoons of bourbon to the butterscotch sauce for a grown-up twist. The bourbon adds warmth and complexity to the caramel flavor.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 4 days. Bring to room temperature before serving.

Freezer

Freeze unfrosted cake layers for up to 2 months. Frosted cake can be frozen for up to 1 month, but the texture may change.

Reheat

Reheat individual slices in the microwave for 10-15 seconds to warm the sauce, or serve at room temperature.

Store leftover cake in an airtight container in the refrigerator for up to 4 days. The cake is best served at room temperature, so take it out of the fridge about 30 minutes before serving.

The butterscotch sauce may soak into the cake slightly, but it will still be delicious. The pecans will lose some crunch over time, but the flavor will remain.

The cake layers can be baked and frozen for up to 2 months. Wrap them tightly in plastic wrap and foil. The frosting can be made a day ahead and refrigerated; let it come to room temperature and re-whip before using.

The butterscotch sauce can be made ahead and reheated gently. The chocolate curls can be made a day ahead and stored in a cool, dry place.

Serving ideas

Serve this cake as the grand finale to a dinner party or at a birthday celebration. Cut generous slices and place them on dessert plates.

A dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream on the side would be lovely, though the cake is rich enough to stand alone. Pour a little extra warm butterscotch sauce over each slice for an extra indulgent touch.

The cake is best enjoyed the day it is assembled, when the layers are moist and the pecans are at their crunchiest. If there are leftovers, they are still wonderful the next day, but the texture will be softer. Pair with a cup of strong coffee or a glass of cold milk to balance the sweetness.

Butterscotch Pecan Layer Cake with Brown Butter Frosting

Prep 40 minCook 35 minTotal 1 h 15 minServes 12

Ingredients

• 3 9-inch butterscotch cake layers, store-bought or made ahead
• 2 cups mascarpone cheese
• 1/2 cup unsalted butter, softened
• 1/2 cup butterscotch sauce, plus more for drizzling
• 2 cups confectioners' sugar
• 1 tsp vanilla extract
• 1 1/2 cups toasted pecan halves
• 4 oz caramelized blonde coverture chocolate, in a solid block
• 1/2 cup warm butterscotch sauce
• 1 cup candied pecan praline
• flaky sea salt, for sprinkling, to taste

Instructions

1. Chop the toasted pecan halves into small pieces and set aside. Grate the solid block of caramelized blonde coverture chocolate on the large holes of a box grater to create a pile of golden chocolate curls. Set the curls aside in a cool place so they do not melt.
2. In a large bowl, beat the mascarpone cheese and softened butter with an electric mixer until smooth and creamy. Gradually add the confectioners' sugar, beating until light and fluffy. Mix in the vanilla extract and 1/2 cup butterscotch sauce until fully combined and smooth.
3. Gently warm the extra butterscotch sauce in a small saucepan over low heat or in a microwave-safe bowl in 15-second intervals, stirring between each, until it is warm and pourable. Set aside but keep warm.
4. Place one cake layer on a serving plate or cake stand. Spread a generous amount of the mascarpone butterscotch frosting over the top, reaching the edges. Top with the second cake layer and repeat with more frosting. Place the third layer on top, then spread a thin crumb coat over the entire cake. Chill for 15 minutes to set.
5. Spread the remaining frosting over the top and sides of the cake, creating swirls or a smooth finish as desired. Make sure the top is level and the sides are fully covered.
6. Pour the warm butterscotch sauce over the crown of the assembled cake, starting from the center and letting it flow outward. Use a spoon or offset spatula to guide the sauce to the edges so it drips down the sides in an even pattern.
7. Pile the candied pecan praline generously on top of the cake, covering the surface completely. Press lightly to help them adhere. Sprinkle the chopped toasted pecans over the praline for extra crunch and texture.
8. Drizzle extra warm butterscotch sauce over the pecans, letting it cascade down the sides. Sprinkle with flaky sea salt. Slice a thick triangular wedge and lift it onto a metal cake server to serve, showing off the layers, chocolate curls, and creamy frosting.
