I tried baking brownies with black beans to be healthier. They came out gummy and tasted a bit off. Most people swear by these swaps, but I think they ruin dessert. My hot take is that fake healthy treats are a waste of time. The mistake was skipping real ingredients for a trend. Now I just bake normal sweets and eat less. Trust me, beans do not belong in brownies.
I used to be all in on those swaps, tried chickpeas in cookie dough and avocado in frosting. The texture was always a little weird, like it was trying too hard. After one too many sad, dense desserts, I went back to a regular butter and sugar brownie recipe. Cutting a smaller piece of the real thing just hits different.
