In times of stress, and SHTF would create a lot of stress, it’s good to have some comfort food to help bring the stress down to bearable levels. While sugar isn’t good to eat in excess, during stressful times, sugar helps release dopamine, which makes you feel good.
I found a cake that can be made with common prepper foods, here it is
2 cups flour
2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup butter (from canned butter, or use shortening)
1 cup sugar
3 eggs (or 6 tablespoons egg powder + 9 tablespoons water)
2 teaspoons vanilla extract
3/4 cup reconstituted powdered milk
Pour everything into a large bowl, mix together (a wire whisk works great here), butter an 8×8 pan (or equivalent), bake at 350 degrees F for 35 minutes or a toothpick comes out clean. Cool and dust with powdered sugar, or mix powdered sugar with a little water or reconstituted powdered milk to make an icing.
