Banana & nuts sponge biscuit

Ingredients

Biscuit

5 eggs (5 pc)

120 grams (4.2 ounces) sugar

150 grams (5.3 ounces) flour

250 grams (8.8 ounces) banana puree

5 grams (0.18 ounces) corn starch

50 milliliters (1.7 fluid ounces) vegetable oil

10 grams (0.35 ounces) baking powder

1 teaspoon (0.17 fluid ounces) wine vinegar

5 grams (0.18 ounces) vanillin

50 grams (1.8 ounces) pecans

50 grams (1.8 ounces) walnuts

Instructions

Step 1

Step 1: Fry the nuts in a dry frying pan until they are fragrant and lightly toasted. Grind them into crumbs. This will enhance the flavor and texture of the final biscuit.

Step 2

Step 2: In a mixing bowl, whip the eggs with the sugar until the mixture is fluffy and pale. Sift the flour, corn starch, baking powder, and vanillin into the mixture and gently stir with a spatula from the bottom to the top. Be gentle to maintain the airy texture of the batter.

Step 3

Step 3: Blend the bananas until they form a smooth puree. Mix this puree with the vegetable oil and wine vinegar. Add the mixture to the dough and combine well. Add the ground nuts and gently fold them in. Ensuring the puree is smooth will help achieve a uniform texture in the biscuit.

Step 4

Step 4: Pour the batter into 2 baking molds, each 18 cm (approximately 7 inches) in diameter. Preheat your oven to 170°C (338°F). Bake the biscuits for 45 to 55 minutes, checking for doneness with a dry skewer. If the skewer comes out clean, the biscuits are done.

Step 5

Step 5: Once baked, allow the biscuits to cool. Wrap the cooled biscuits in foil and place them in the fridge overnight. Each biscuit should be approximately 4 cm (1.6 inches) high. The next day, cut the biscuits into 4 layers. Cooling the biscuits overnight helps in easier slicing and enhances the flavor.

Step 6

Step 6: Enjoy your delicious banana pecan walnut sponge biscuits! Bon Appetit!
