FREQUENTLY ASKED QUESTIONS:

Is this overly tart?

No, this Lemon Fudge is actually the perfect combo of flavors. It’s a sweet fudge and the primary flavor of this fudge comes from the white chocolate with the secondary flavors being the condensed milk and lemon taste. You really only get a bit of tartness from the lemon zest on top (if you choose to add it.)

Why do I need to heat treat the cake mix?

Heat treating cake mix makes it safer to eat. Since cake mix has uncooked flour in it, you shouldn’t eat it unless it’s been properly heated to a high enough temperature so that it kills any possible bacteria.

How to heat treat cake mix in the microwave:

Using the microwave is a really easy way to heat treat cake mix. To do so, microwave the cake mix in a microwave safe bowl for (2) 30-second intervals stirring in between. Let the cake mix come to room temperature before using it in your fudge mixture. 

How to heat treat cake mix in the oven:

Line a baking sheet with parchment paper, spread out the cake mix so it’s even across the whole sheet. Bake at 350F for 5 minutes and then let it cool down to room temperature before using the cake mix.  

How should I prep my 8×8-inch baking dish?

I think it’s easiest to use parchment paper so you can easily pull it out of the baking dish. You don’t have to do this if you have a nonstick baking dish but it does make it much easier to handle and to remove.

What should I do with the rest of the leftover cake mix?

Leftover cake mix can be used to make another cake. We like this idea shared from Spruce Eats. It’s the perfect way to make sure that you don’t have any food waste!

How to store leftovers?

Leftover lemon fudge pieces should be stored in an airtight container and should be kept in the fridge for up to a week (but I don’t think it will last that long!) I suggest using a piece of parchment paper in between the layers of fudge so they don’t get stuck together.

Pour mixture into the center of the 8×8 dish, scraping any excess fudge mixture from the pan using your spatula. The fudge should self level well, requiring zero spreading.

Notes

  • Refer to my FAQ on how to heat treat cake mix (in the microwave or the oven.) 
  • As you’re stirring the mixture, use your spatula to break up any pieces of butter that do not melt as easily as others. Do this by gently pressing it with your spatula. 
  • Be sure to use butter that is softened to room temperature. Butter any cooler will be harder to break down over low heat. 
  • We prefer to eat this fudge chilled but it is good at room temperature. 
  • Be sure to store this fudge in an airtight container inside the refrigerator. 
  • Refer to my FAQ’s for additional information.
