A while back you posted a recipe for yum Yum brownie muffins. cake mix and pumpkin nothing else. but what is the oven temp. you posted 499º but I don't think that could be correct, also said to bake for 29 minutes???
I'm thinking I might make these to take to a party.

Judy, You probably have forgotten, but Sandy is no longer with us.   I would assume the temp would be 350.  Look at the muffins at 20 minutes they may or may not be ready.  If not given them another 5 minutes.    Helen

I'm sorry I had forgotten, Sometimes I just don't think.
I did Google the recipe and found it. on a site that Sandy must have gotten it from. Hungry Girl.com  181 calories 3.5 g fat- 37g carbs-2g fiber-2g protein- 4 ww points

Yum Yum Muffins

1 box devil's food cake mix and 1 can (15 OZ) pumpkin. mix together, nothing else added. mixture will be very thick and you will be tempted to add in other things to make the batter smoother, do not do this as it will ruin everything. place batter into muffin tins, or mini muffin tins, lined with paper, or sprayed with non stick spray. bake at 400º for 20 minutes. makes 12 regular or 36 mini muffins
