  • 1/4 cup unsweetened cocoa powder
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 cup almond flour

Directions

Description

Une fusion paradisiaque de brownies fondants et de biscuits aux pépites de chocolat fondants, couronnés de noisettes grillées et de morceaux de chocolat fondants : ces brookies épais de style boulangerie sont riches, noisetés et totalement irrésistibles.


Ingredients

  • 1/2 tasse de compote de pommes non sucrée
  • 1/2 tasse de sirop d’érable ou d’agave
  • 1/4 tasse de poudre de cacao non sucrée
  • 1/4 cuillère à café de sel
  • 1/2 cuillère à café de bicarbonate de soude
  • 1/2 tasse de farine d’amandes
  • 1/4 tasse de farine d’avoine
  • 1/2 cuillère à café d’extrait de vanille
  • 1/4 tasse de beurre d’arachide ou de beurre d’amande
  • 1/4 tasse de sucre de coco
  • 1 cuillère à soupe de lait végétal
  • 1/2 cuillère à café d’extrait de vanille
  • 1/4 tasse de farine d’avoine
  • 1/4 cuillère à café de bicarbonate de soude
  • 1/4 tasse de morceaux de chocolat noir
  • 1/4 tasse de noisettes grillées hachées

Instructions

  1. Préchauffer le four à 350 °F (175 °C) et chemiser un moule à muffins de cercles de papier sulfurisé ou de moules en silicone.
  2. Dans un saladier, mélangez tous les ingrédients de la base du brownie jusqu’à obtenir une consistance lisse. Déposez environ 2 cuillères à soupe de pâte au fond de chaque coupelle.
  3. Dans un autre bol, mélanger le beurre de noix, le sucre de coco, le lait et la vanille. Ajouter la farine d’avoine et le bicarbonate de soude, puis incorporer les pépites de chocolat et les noisettes.
  4. Déposez des cuillerées de pâte à biscuits sur la base du brownie et appuyez doucement pour aplatir légèrement.
  5. Cuire au four pendant 18 à 20 minutes, ou jusqu’à ce que le dessus des biscuits soit doré et légèrement ferme au toucher.
  6. Laisser refroidir dans le moule pendant 10 minutes avant de transférer sur une grille.

Notes

  • Pour une version sans noix, utilisez du beurre de graines de tournesol et omettez les noisettes.
  • Laissez refroidir brièvement la pâte à biscuits pour la manipuler plus facilement si elle est trop molle.
  • Conserver dans un contenant hermétique jusqu’à 5 jours ou congeler pour une durée de conservation plus longue.
