Taken almost directly from Plant Based On a Budget. Trust me when I say that you've gotta give this website a try!
I didn't have orange marmalade (like their recipe called for)... but we try to always have lingonberries in the cabinet. You know, for lingonberry emergencies.
2 c wheat flour
1/2 t baking powder
1/2 t baking soda
2 t flax meal + 2 T water
1/2 c oil
3/4 c raw sugar
1/2 c lingonberry jam (ours is from IKEA)
2 1/2 c grated squash
1/2 t salt
1/2 c steel cut oats
Grate your squash.
In a large bowl mix flour, salt, baking soda and baking powder.
In a small-med bowl mix sugar, oil, flax+water and lingonberries. Mix WELL. Add the squash and mix, mix, mix.
Now pour the oil mixture into the flour bowl and stir well.
Add the oats and stir until just mixed.
Oil your pan(s). You can use one 9"x5" pan or separate them into smaller pans, which is what I did. Leave some room because the bread will rise as it bakes.
Your house will smell unbelievably yummy. It took all of my willpower not to open the oven early. Wow. Trust me. You WANT this tea cake.
