“Happiness doesn’t have to be complicated. Sometimes it begins with a handful of simple ingredients and a warm oven.”

Welcome to Sprinkle Goodies – Where Baking Meets Happiness!

Recipe at a Glance

• Prep time: 15 minutes
• Bake time: 50–60 minutes
• Cooling time: about 1 hour
• Total time: approximately 2 hours
• Yield: 8–10 slices
• Pan size: 25 × 13 cm (about 9.8 × 5.1 inches; approximately 2 inches deep)
• Oven: 175°C / 350°F
• Difficulty: Easy

Ingredients

• 170 g oat flour (about 1¾ cups, spooned and levelled)
• 1 teaspoon baking powder
• 20 g unsweetened cocoa powder (about ¼ cup)
• 4 very ripe bananas, mashed (approximately 400–450 g peeled, depending on size)
• 3 large eggs, separated
• 100 g walnuts, finely chopped (about 1 cup)
• 1 additional ripe banana, sliced, for the topping
• A few walnut halves and a sprinkle of rolled oats, optional
• Melted dark chocolate for drizzling, optional

Note: Cup measures are approximate; weighing the ingredients gives the most consistent result. This recipe contains eggs and walnuts. The batter has no added sugar, but its sweetness depends on how ripe the bananas are.

Instructions

1. Preheat the oven to 175°C / 350°F. Line a 25 × 13 cm (9.8 × 5.1-inch) loaf pan with parchment paper.
2. Finely chop the walnuts. Reserve a few walnut halves for decorating, if desired.
3. Mash the four very ripe bananas with a fork until mostly smooth.
4. Separate the eggs. Beat the egg whites in a clean bowl until stiff peaks form. In another bowl, whisk the egg yolks with the mashed bananas until combined.
5. In a separate bowl, mix the oat flour, baking powder, cocoa powder, and chopped walnuts.
6. Add the dry mixture to the banana and egg yolk mixture. Stir until evenly combined, without overmixing.
7. Gently fold the whipped egg whites into the batter in two or three additions, using a spatula to keep as much air in the mixture as possible.
8. Transfer the batter to the prepared pan and smooth the top. Arrange the sliced banana over the surface and add walnut halves and rolled oats if desired.
9. Bake for 50–60 minutes. Test the centre with a wooden skewer; it should come out without wet batter. A few moist crumbs are fine.
10. If the top begins to brown too quickly, loosely cover the loaf with aluminium foil and continue baking until the centre is cooked.
11. Let the loaf cool in the pan, then lift it out and cool completely. Drizzle with melted dark chocolate if desired, allow it to set, slice, and serve.

Baking Tips

• Very ripe, brown-spotted bananas give the loaf the best natural sweetness and banana flavor.
• Whip the egg whites until stiff peaks form, then fold them in gently to help lighten the texture.
• Oat flour and bananas make a moist crumb, so check the centre rather than relying on the surface colour alone.
• If the top browns too quickly, cover it loosely with foil.
• Let the loaf cool completely before slicing for cleaner pieces.

Storage

• Room temperature: Store airtight in a cool place for 1–2 days.
• Refrigerator: Store airtight for up to 4–5 days.
• Freezer: Slice, wrap individually, and freeze for 2–3 months for best quality.

Because the loaf contains fresh banana and no added oil or butter, refrigerate it if your kitchen is warm or if you plan to keep it for several days.

Frequently Asked Questions

Can I use all-purpose flour instead of oat flour?

Yes. The texture may change slightly. Mix just until combined, as different flours absorb moisture differently.

Can I leave out the walnuts?

Yes. Omit them or replace them with pecans, hazelnuts, or chocolate chips.

Why separate the eggs?

Whipped egg whites introduce air and help make the loaf lighter.

How do I know when it is done?

Insert a wooden skewer into the centre. It should come out without wet batter. Cover the top loosely with foil if it browns before the centre is ready.

Can I skip the chocolate drizzle?

Absolutely. It is optional; the loaf already has cocoa and banana flavor.

Is it sweet without added sugar?

There is no added sugar in the batter. The sweetness comes mainly from the ripe bananas, so the result will be less sweet than a traditional sugar-sweetened cake.
