Recipe Questions & Answers

Can I make this vegan?

Yes, substitute the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes) and use plant-based milk. The texture remains just as tender and satisfying.

What type of protein powder works best?

Vanilla whey or casein protein powder blends smoothly and adds pleasant flavor. Chocolate or unflavored varieties also work well. Plant-based protein powders may absorb more liquid, so you might need to add an extra tablespoon of milk.

Can I prepare this ahead of time?

Mix the dry and wet ingredients separately the night before, then combine and bake in the morning. Leftovers also reheat beautifully—just warm in the microwave for 30-60 seconds and add a splash of milk if needed.

How do I know when it's done baking?

The oats are finished when the center is just set and the top is golden brown, around 22-25 minutes. A toothpick inserted should come out mostly clean with a few moist crumbs. It will continue to firm up slightly as it cools.

Can I use different mix-ins?

Absolutely. Try adding chopped walnuts, pecans, or chocolate chips to the batter. Blueberries or chopped apples also pair wonderfully with the cinnamon swirl. Just keep total add-ins to about ¼ cup to maintain proper baking time.

Is this gluten-free?

It can be! Use certified gluten-free rolled oats and ensure your protein powder is labeled gluten-free. With these simple swaps, those with gluten sensitivity can enjoy this warm, comforting breakfast.
