I finally created my own recipe for some chewy wholesome bars that are great for our 2.7 year old to eat. Next time I'll try roll them into cigar shapes or more long and thin bars so they might look a bit more 'attractive' to her.
1 c oats
1 c sunflower seeds
1/2 c almond meal
1 tsp baking powder
1 c dates, soaked for a while until soft (you can also use raisins, prunes or a mix)
1 tsp cinnamon
1 egg

Preheat oven to 180C. Line a 20x20cm baking tin.
Grind the oats and sunflower seeds in a food processor until it resembles a flour. Add almond flour, dates, baking powder and cinnamon and grind until well mixed and it forms a ball. Transfer to a bowl and mix in an egg.
Press mixture into the baking tin and even out with your fingers or back of a spoon. Use a knife to cut into pieces int he tin. Bake in oven for 15-20 until golden. Leave to cool then break into pieces.
