Pastry & Baked-Good Ratios

Frangipane (Almond to Butter to Sugar to Egg, 1:1:1:1)

Also: crème frangipane, almond cream ratio, crème d'amande

Equal weights of ground almond, butter, sugar, and egg — the almond cream filling that bakes from a loose paste into a moist, cakey interior in tarts, galettes, and pastries.

Frangipane (properly crème d'amande, or almond cream) is a four-ingredient filling defined by its 1:1:1:1 weight ratio: ground almonds, butter, sugar, and eggs. Mixed raw and spread into unbaked pastry shells, it bakes into a moist, slightly cakey, deeply almond-flavored layer that sets firmly enough to hold fruit or be sliced cleanly. The equal-weight ratio ensures that the fat (butter + almond fat) and the protein/water from eggs balance each other perfectly, producing neither a greasy nor a dry result. True frangipane (in professional usage) sometimes refers to a crème d'amande lightened with pastry cream, but in home and artisan baking the pure 1:1:1:1 almond cream is universally called frangipane.

The proportions

Ground almonds (almond flour / blanched almond meal) · 1 part (e.g. 125 g)Unsalted butter · 1 part (e.g. 125 g)Sugar (icing/powdered or caster) · 1 part (e.g. 125 g)Whole eggs · 1 part (e.g. 125 g, approximately 2.5 large eggs)
1 part (e.g. 125 g)
Ground almonds (almond flour / blanched almond meal)Blanched (skin-off) gives a pale, fine texture; unblanched adds color and a slightly more rustic flavor; use fine-ground for smoothest filling
1 part (e.g. 125 g)
Unsalted butterAt room temperature for easy creaming; European-style high-fat butter yields a richer result
1 part (e.g. 125 g)
Sugar (icing/powdered or caster)Icing sugar produces a smoother, less grainy filling than granulated; caster sugar is acceptable if creamed thoroughly
1 part (e.g. 125 g, approximately 2.5 large eggs)
Whole eggsAdded one at a time to prevent the emulsion from breaking; egg provides moisture, protein structure, and lift

Method

Beat butter and sugar together until pale and fluffy. Add the ground almonds and mix until incorporated. Add eggs one at a time, beating well after each addition until the filling is smooth, cohesive, and slightly glossy. The filling can be used immediately or refrigerated for up to 5 days. Spread into a pre-baked or raw pastry shell to a depth of 1–2 cm, top with fruit or bake plain, and bake at 350–375 °F (175–190 °C) until puffed, set at the center, and golden — about 25–35 minutes depending on depth.

Tips

  • Do not overbake — frangipane should be just set at the center with a slight wobble; it continues to set as it cools and becomes cakey rather than custard-like if overbaked.
  • The filling can be piped with a piping bag for precise tarts or spread with an offset spatula; either way, leave 5 mm of headspace as it puffs during baking.
  • Adding 1–2 tablespoons of rum, amaretto, or kirsch to the filling before baking adds complexity and keeps the crumb especially moist.
  • Fruit pressed lightly into the surface before baking (pear halves, apricots, cherries) sinks slightly as the frangipane rises around it — always cut fruit to a uniform thickness for even baking.
  • If the filling curdles when eggs are added, the butter was too cold. Return to room temperature and beat vigorously; it usually re-emulsifies.
  • A thin layer of jam (apricot, raspberry) spread on the pre-baked tart shell before adding frangipane adds a flavor bridge and seals the pastry against sogginess.

Variations

  • Pistachio Cream (Pistachine)

    Substitute all or half the almond flour with ground pistachios; add a touch of almond extract to amplify the nut flavor

  • Hazelnut Frangipane (Praliné)

    Replace almonds with ground toasted hazelnuts; the natural fat content is similar; pairs exceptionally with chocolate or pear

  • Coconut Cream Filling

    Replace almonds with desiccated coconut and reduce butter slightly to account for coconut's higher fat content; used in tropical tarts

  • Lightened Frangipane (with pastry cream)

    Fold in equal volume of pastry cream to the finished almond cream; produces a lighter, more mousse-like texture — the classic professional 'frangipane'

  • Brown Butter Frangipane

    Brown the butter to beurre noisette before using; adds toasted, nutty depth; allow to re-solidify before creaming

Related ratios

  • Tart Dough / Pâte Sablée (1:2:3)

    The standard pastry shell into which frangipane is baked; short dough's richness complements the almond cream

  • Marzipan (2:1 almond to sugar)

    A related almond-sugar paste but very different in use — marzipan is sweet, pliable, and raw; frangipane is a baked filling

  • Pastry Cream (3:2:1)

    Folded into frangipane to create lightened professional-style almond cream; adds custard softness

  • Pound Cake (1:1:1:1)

    Same equality ratio as frangipane but baked as a standalone cake; frangipane is denser and used as a filling, not a crumb

Notes

Frangipane vs. marzipan — a common confusion

Frangipane and marzipan are frequently confused because both involve ground almonds and sugar, but they are fundamentally different preparations. Marzipan is a cold-process paste: finely ground almonds and sugar are worked together with a binding agent (egg white, rose water, or glucose syrup) to form a pliable, plastic dough used for modeling and coating. Frangipane is an unbaked cream that contains butter and whole egg and is always baked into a pastry shell. Marzipan has a pure, clean almond-sugar sweetness. Frangipane has a richer, more complex baked flavor — caramelized sugars, toasted almond fat, eggy custardy notes — and a cakey texture rather than a dense, chewy one.

Why the 1:1:1:1 ratio works

Almond fat (about 50% of almond weight) plus butter fat together give frangipane its characteristic richness. Equal-weight egg counterbalances this fat load with water and protein: the water steams during baking, creating lift, while the protein coagulates to set the filling. Equal-weight sugar both sweetens and controls browning. The four components at equal weight hit a natural equilibrium — enough fat for moisture and flavor, enough protein for structure, enough sugar for sweetness without excessive caramelization. Increasing any one component at the expense of the others predictably tilts the filling: more almond = drier and denser; more butter = greasier; more egg = more custard-like; more sugar = sweeter and more prone to over-browning.
