Preheat oven to 350℉ (180℃). Line a baking pan with parchment paper.
Spread the almond flour in an even layer across the pan. Bake for 10 minutes, stirring the flour every 3 minutes with a spatula for an even toast. Set aside to cool completely (about 20 minutes).
Frangipane Almond Cream
Stir the vanilla and almond into the beaten eggs. Whisk together the toasted almond flour and all purpose flour in a small bowl.
20 grams all purpose flour, 100 grams eggs, ¾ tsp pure vanilla extract or vanilla bean paste, ¾ tsp almond extract, 100 grams almond flour
Place the butter and sugar in the bowl of a stand mixer fitted with a paddle attachment. Cream on medium speed for about 3 minutes until pale and fluffy.
Mixing on low speed, add in a third of the flour mixture, followed by a third of the eggs. Repeat until all the flour and eggs have been incorporated. Scrape bottom and side of the mixing bowl as needed.
To add rum, mix it in at the very end.
15 grams rum
Don't over mix. It should look like a soft textured paste.
Transfer to airtight container and refrigerate until ready to use. Allow the frangipane to come back to room temperature for a spreadable consistency to fill and bake inside pastries.
Notes
Almond cream is used as a pastry filling that must be baked. It is not for raw consumption due to the uncooked eggs.
