Tips, Tricks & FAQs
Yes – you can definitely use frozen blueberries – especially when baking. They hold up very well and are pretty much interchangeable! Go for it!
Yes definitely! Adding white chocolate chips with semi-sweet chocolate chips and the chocolate batter would be so good – especially since blueberries & white chocolate are a great combo!
I added sour cream in this instance but mayonnaise, apple sauce and pudding are also known to add a nice moisture factor.
You can if you like – I hate losing any of the cupcake to the paper liners – so I usually just spray my pan with non-stick spray.
If you’re going to keep them out – I just store them in an airtight container on the counter for up to 5 days.
Yes! I’m on my own right now and didn’t want to eat these 6 days in a row so I kept 3 out for breakfasts & snacks and froze 3. I wrapped them individually in plastic wrap – then popped them in a freezer bag. Now I can take out one at a time whenever I want!
