Protein Flapjack Recipe (vegetarian / vegan / lactose-free)

Protein Flapjack Recipe (vegetarian / vegan / lactose-free)

Ready-made protein flapjack

Flapjacks are British "oat biscuits" and the counterpart to German granola bars. However, the flapjack is baked and not just pressed. Because of their high calorie content, flapjacks are very popular with strength athletes and hardgainers, but also with endurance and amateur athletes. In addition, the muesli cakes are usually quite juicy and a great source of calories.

Here I present you a protein flapjack recipe, which I put together for my requirements. The result can also be called a weight-gainer bar. Enrichment with protein powder aims to provide the muscles with valuable protein building blocks. As is well known, these serve not only to build muscle, but also to maintain muscle, which is important for everyone who does sports.

The Flapjack recipe is vegetarian. However, I have added the vegan alternatives to the recipe ingredients used. By using the vegan ingredients, the Flapjack is also lactose-free.

Ingredients Protein Flapjack Recipe:
for approx. 9 flapjack bars each 90 grams

  • 300 g oatmeal, tender
  • 150 g Whey-Proteinpulver (Vegane Variante: Soy Protein Powder)
  • 100 g peanut butter, natural
  • approx. 150 ml low-fat milk (vegan variant: almond milk)
  • 80 g honey, liquid (vegan variant: maple syrup or agave syrup)

When choosing the ingredients, everyone can decide for themselves which food quality they want to use. When it comes to protein powder, I usually use a whey protein concentrate with a chocolate flavor. This is my favorite when paired with the peanut butter.

Protein flapjacks, the practical companion for on the go

Since the protein flapjacks can be prepared quickly and easily as described, the flapjacks can e.g. simply take with you as a snack for on the go. Even in ancient England, workers liked to take flapjacks with them as food for their journeys.

I keep the flapjacks in a box in the refrigerator, in the vegetable compartment. They can be kept for several weeks, but not exactly safe from unauthorized removal ...

Tips and notes on preparation:

* 1 A tablespoon is sufficient for mixing in all steps.
* 2 With the natural peanut butter, the oil is deposited on the surface. From half the glass you usually only have a firm, crumbly peanut mixture. I then just add some walnut oil to the recipe.
* 3 If the mixture remains too crumbly, a little more of the milk can simply be added. However, this increases the baking time slightly or by a few minutes.
* 4 The spread shape of the mass should be fairly rectangular if you want to cut bars from it later. If you prefer it crispy, spread the mixture no thicker than 1 cm thick.
* 5 Better to bake a little too short than too long, otherwise the Protein Flap Jacks will get too dry. Unless you want them crispy (see * 4).
