I was just baking up a cake for my grandma's birthday and just realized that I am out of eggs. Baby is asleep so now way for me to get out.

I just reverse creamed the dry ingredients (cake flour, baking powder, sugar and salt) with butter and buttermilk.

Will this portion of the cake be ok to sit for a while until I can get some eggs, or will I have to toss it??

Thanks in advance!

Put it in the fridge. It may be okay. Don't leave it sitting out.

thank you!

I know you can substitute 1 tbsp soy flour and a tsp or 2 of water per egg in a recipe. I've used this in muffins several times and never had a rising issue. But I don't know if I'd do it for the first time in a cake for someone else.

I agree with kascarlett. Just stick it in the fridge for a bit, and then once you've got eggs, let the bowl, sit out until room temp again and whip it up again until it's fluffy. By then the eggs will be room temp too.
