Pecan Praline Cake

the Louisiana celebration layer cake: two moist butter-cake layers filled and frosted with silky pecan praline buttercream, crowned with a shatter of homemade pecan praline, the New Orleans confection tradition turned into a festive centrepiece

Origin: New Orleans, Louisiana, USA

From the journey of Pecan.

The pecan praline cake is the Louisiana festive table's most ambitious expression of the praline tradition: the flavour and texture of the New Orleans street candy, translated into a layered celebration cake. It belongs to the lineage of Southern American layer cakes (the caramel cakes, the coconut cakes, the Lane cake of Alabama) but with a specifically Louisiana identity rooted in the praline culture of New Orleans. Southern American layer cake-making is one of the great vernacular baking traditions of the continent, and the Louisiana version carries all of its characteristic elements: a generous, yielding butter-cake sponge; a frosting applied in thick, pillowy swirls that doubles as the cake's structural decoration; and a crowning flourish that makes the occasion explicit — here, the broken shards of homemade pecan praline embedded in the frosting, their pale, crystalline sweetness contrasting with the amber praline buttercream beneath. The praline buttercream is the heart of the recipe: it is made by cooking a traditional New Orleans praline mixture to the soft-ball stage, cooling it, and then beating it into softened butter in the manner of a Swiss-meringue-style buttercream. The result is a frosting of astonishing depth (caramel-sweet, pecan-fragrant, slightly sandy in texture where the fine crystallised sugar caught in the butter) that is far more complex than a standard American buttercream and far more suited to the warm, indulgent climate of the New Orleans table.

Ingredients

Cake

280 g plain flour
2 tsp baking powder
0.5 tsp fine salt
225 g unsalted butter, softened
300 g caster sugar
4 large eggs, at room temperature
2 tsp vanilla extract
240 ml buttermilk, at room temperature
150 g pecan halves, toasted and roughly chopped, for folding into the batter

Praline Buttercream

200 g caster sugar
100 ml double cream
60 g unsalted butter
0.25 tsp fine salt
1 tsp vanilla extract
340 g additional unsalted butter, softened to room temperature, for the buttercream base

Decoration

80 g pecan pralines (from the pralines recipe, or made fresh for this cake), broken into shards

Method

Preheat the oven to 180°C / 160°C fan. Grease and line two 20 cm round cake tins. Whisk together the flour, baking powder, and salt. In a large bowl, beat the butter and caster sugar for the cake until very pale and fluffy, about 5 minutes. Beat in the eggs one at a time, then the vanilla.
Fold in the flour mixture in three additions alternating with the buttermilk in two additions, beginning and ending with the flour. Fold in the chopped toasted pecans. Divide evenly between the prepared tins. Bake for 30–35 minutes until a skewer inserted in the centre comes out clean. Cool in the tins for 10 minutes, then turn out onto a rack to cool completely.
Make the praline base for the buttercream: combine the 200 g caster sugar, double cream, 60 g butter, and salt in a heavy saucepan. Cook over medium heat, stirring until the sugar dissolves, then boil without stirring to 114–115°C (soft-ball stage). Remove from heat, add the vanilla, and pour into a clean heatproof bowl. Beat vigorously until the mixture turns opaque, pale, and thickened (the praline stage). Allow to cool completely to room temperature.
Beat the 340 g softened butter in a stand mixer until very pale and fluffy, about 5 minutes. Add the cooled praline mixture a spoonful at a time, beating on medium speed after each addition, until all the praline is incorporated and the buttercream is smooth, silky, and spreadable.
To assemble: place one cake layer on a serving plate. Spread generously with praline buttercream. Top with the second layer. Frost the top and sides of the cake with the remaining buttercream, creating swirls with the back of a spoon or a palette knife.
Press the broken praline shards into the top and sides of the frosted cake just before serving, so the praline retains its snap. Serve within 4–6 hours of assembly.

Notes

The praline buttercream is more labour-intensive than a standard American buttercream but far superior in flavour: the caramelised sugar gives it a depth that icing sugar and butter cannot replicate. If the praline base seizes in the pan before you can pour it, add 1 tablespoon of warm cream, return to very low heat, and stir until liquid again. The assembled cake keeps refrigerated for up to 2 days; bring to room temperature for 30 minutes before serving so the buttercream softens.
