Common Questions
Can I bake this in a 9x13 pan instead of a round?
Yes. A 9x13 makes a thinner cookie cake, so it bakes faster. Press the dough evenly into a lightly greased 9x13 pan and bake about 20 to 24 minutes, starting to check at 18. You want lightly golden edges and a center that no longer looks glossy or wet. A toothpick should come out with a few moist crumbs, not wet batter.
Why is the bake time longer in a 9-inch round pan?
Because it is basically deep dish. The dough layer is much thicker in a 9-inch round, so it needs more time for the center to cook through. Expect about 32 to 38 minutes at 350°F, but pan color and material can shift timing by 5 to 10 minutes. Trust the visual cues more than the clock.
How do I tell when the center is done?
Look for golden edges and a center that is set, not jiggly, and not shiny. A toothpick should come out with a few moist crumbs. If it comes out with wet batter, it needs more time.
How do I avoid an overbaked, crunchy cookie cake?
Pull it when the edges are golden and the center is set but still looks slightly soft. It keeps cooking as it cools. Also measure flour by spooning into the cup and leveling. Packed flour makes it dry fast.
What berries work best for the swirl?
Raspberries and strawberries give the brightest flavor. Blueberries work too, but the skins can stay a little obvious. Cook them down a bit longer and mash very well, or blend and strain for a smoother swirl.
How do I keep the frosting from getting watery?
Cook the berry mixture until it is jammy. You want it thick enough to coat a spoon and leave a trail when you drag your finger through it. Then cool it completely before swirling it into the frosting. Thin, warm berry sauce is the #1 cause of weepy frosting.
Can I make the frosting without cream cheese?
You can use a classic buttercream, but it will be sweeter and less tangy. If you do, add lemon juice and extra salt to keep it balanced.
Do I need a stand mixer?
Nope. A hand mixer is perfect. You can even do it by hand if you are feeling strong and slightly dramatic.
Any springform pan tips?
If you use a springform, make sure the bottom is lined with parchment and snap the ring on tightly. If you are nervous about leaks, set the pan on a sheet pan (or wrap the outside in foil). This dough is thick, so leaks are rare, but peace of mind is free.
