Storing Leftovers
After it cools off, just cover and leave it out at room temp for up to three days To keep it longer, put it in the fridge and it’ll last a week Want to freeze it? Slice it up or leave it whole, wrap in plastic a couple of times, then stash in a freezer bag for two months Max. To eat, thaw in the fridge overnight or zap a piece in the microwave when you need a little treat
Swaps For Ingredients
If you’re short on cake flour, use all-purpose but scoop out two tablespoons per cup and swap in cornstarch for them Want something a bit lighter? Half Greek yogurt swaps in for sour cream Any almond extract will add a fun twist instead of vanilla Some lemon zest is perfect if you love a fresh kick
How To Serve
Absolutely shines next to a handful of berries or a big puff of whipped cream Go traditional with powdered sugar If you’re feeling fancy, drizzle glaze on top or plate it with fruit compote What I love most: a warm slice plus a cup of coffee with milk for a cozy pick-me-up any afternoon
