Method
Preheat the Oven
Start by preheating your oven to 160°C (320°F). This step is crucial to ensure the oven is at the right temperature when you’re ready to bake, helping your Protein Biscoff Banana Slices cook evenly and rise perfectly.
Mash the Bananas and Combine Wet Ingredients
Take your ripe bananas and peel them. Then, place them in a mixing bowl and mash them thoroughly until smooth. You want the bananas to be as mushy as possible to create a soft base for your batter. Once mashed, stir in the milk and the liquid sweetener of your choice . This will add moisture and sweetness to your mixture, ensuring a soft and flavorful result.
Mix the Dry Ingredients
In a separate bowl, combine the dry ingredients grenadeofficial vanilla protein powder, self-raising flour, sugar, and baking powder. Stir them well to ensure an even distribution of the ingredients. This step is important because it ensures that the baking powder and protein powder are evenly spread throughout the batter, helping it rise and giving your slices the right texture.
Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the mashed banana mixture. Use a spoon or whisk to gently mix everything together. It’s best to combine them slowly, ensuring that no clumps of dry ingredients remain. Keep mixing until you have a smooth and consistent batter.
Pour the Batter into the Baking Dish
Once your batter is ready, pour it into a lined baking dish. Ensure that the dish is lined with parchment paper, which will make it easier to remove the slices after baking. Spread the batter evenly in the dish using a spoon or spatula, making sure it’s level across the top.
Bake in the Oven
Place the baking dish in the preheated oven and bake for 25 minutes. It’s a good idea to check the bake at the 25-minute mark by inserting a knife into the center. If the knife comes out clean, your bake is done. If it has batter on it, give it a few more minutes. Every oven is slightly different, so keep an eye on your bake to make sure it doesn’t overcook or undercook.
Cool the Bake
After the bake has finished cooking, remove it from the oven and let it cool for a few minutes. This is important because it allows the texture to set, making it easier to cut into slices later.
Melt the Biscoff Spread
While the bake is cooling, take the Biscoff spread and place it in a microwave-safe bowl. Heat it for about 30 seconds in the microwave, checking to make sure it melts evenly. Stir the spread once melted to ensure it’s smooth and ready to drizzle.
Drizzle the Melted Biscoff
Once the bake has cooled enough to handle, drizzle the melted Biscoff spread generously over the top. This gives your slices a sweet and indulgent finishing touch. You can also use a spoon to spread the melted Biscoff evenly across the surface, making sure every slice will have a bit of that rich, caramelized flavor.
Refrigerate and Slice
After you’ve drizzled the Biscoff, place the bake in the refrigerator to set. This step will help the topping firm up and make the slices easier to cut. Once it has fully cooled and set, slice the bake into 16 pieces, and your Protein Biscoff Banana Slices are ready to enjoy!
