Blueberry cake: an easy high-protein recipe
Blueberry cake can be sweet, soft and fairly nutritious all at once. Here is a simple version where beans, banana, egg, protein powder and blueberries all go into one batter and the oven does the rest.
Why does blueberry cake work so well?
Your first thought might be: beans in a cake? It’s actually a pretty clever trick. Beans give the batter moisture and softness, yet they aren’t strongly noticeable in the finished cake. If the mixture is blended thoroughly, the result resembles a dense, brownie-like cake more than a bean dish.
Blueberries add freshness and a slightly tart note. That is exactly what keeps the cake from becoming too heavy. The amount of banana is small, 50g, but it’s enough to give the batter a touch of natural sweetness and binding.
This recipe is a good fit when you want something sweet but don’t want to make a classic cake with butter and sugar. The simple fact is, if you have a blender or food processor at home, most of the work is already done.
Blueberry cake: ingredients and amounts
The amounts matter here, because the batter needs to stay thick enough without becoming dry. Keep the recipe unchanged the first time. Once you’ve tried the result, you can adjust the texture to your own taste later.
- 240g beans
- 50g banana
- 2 eggs
- 54g chocolate-flavored whey protein powder
- 60g vanilla Proteini tetra
- 30g peanut butter
- 100g blueberries
If you use frozen blueberries, don’t be alarmed if the batter looks a bit wetter. In that case, let the berries drain a little or add them to the pan last, as the recipe says. Fresh blueberries hold their shape better, while frozen berries release more juice.
How to make blueberry cake
Preheat the oven to 180 degrees. It’s a small thing, but an important one: if you put the cake into a cold oven, the baking time becomes unpredictable and the texture can end up too gooey.
Add all the ingredients to a food processor or blender, except the blueberries if you want to keep the berries whole in the batter. Blend until the mixture is smooth and creamy. You shouldn’t be able to see any pieces of beans. The smoother the batter, the better the cake.
Pour the mixture into a pan lined with baking paper. Now add the 100g of blueberries. You can gently press them into the batter or leave more of them on top. Bake in a 180-degree oven for 20-30 minutes.
So what actually happens in the oven? The edges of the cake set first, while the center stays soft for longer. Don’t wait for a completely dry sponge. This recipe is actually better when the cake stays juicy inside.
Practical tips for a better result
Use baking paper even if the pan seems non-stick. High-protein batters can stick to the pan more easily than ordinary cake batter. With the paper, you can lift the whole cake out once it has cooled.
Let the cake cool before slicing. While warm, it is softer and can fall apart under the knife. If you want cleaner slices, put the cake in the fridge for a while after it has cooled. Honestly, a blueberry cake like this often tastes even better the next day.
When it comes to sweetness, a lot depends on the powders you use and the banana. If the banana is very ripe, the cake will be sweeter. If the banana is firmer and less sweet, the flavor will be more subtle. Don’t make big changes the first time, because the 54g of HERA80 and 60g of Protein Milkshake already give the batter its own flavor.
100g of the cake contains:
- 115.3kcal
- 4.9g fat
- 9.7g protein
- 7.3g carbohydrates
- 1.8g dietary fiber
These numbers make it a good choice for a snack or to go with coffee, especially if you want a sweet bite that isn’t just an empty sugar bomb. Portion size still counts, of course. Cake is cake, even when the ingredients are smarter.
FAQ: blueberry cake in your home kitchen
Can you taste the beans in the cake?
If the batter is blended until properly creamy, usually not. The chocolate-flavored HERA80, vanilla Protein Milkshake, peanut butter and blueberries mask the bean flavor well.
Is blueberry cake suitable after a workout?
It can be, since the recipe has 9.7g of protein per 100g. If you want to eat it as a post-workout food, look at your nutrition across the whole day rather than just a single piece of cake.
Why does the cake need to cool before slicing?
As it cools, the texture becomes firmer. If you cut into the cake straight out of the oven, the center may seem too soft, even though everything is fine once it has cooled.
