Most high-protein crisps just stir protein powder into the crumble topping. This one does something different: a smooth cottage cheese custard bakes right under the apples, so you get a creamy, cheesecake-like layer between the fruit and the crunchy oat topping — not a chalky protein-powder aftertaste anywhere in it.
This warm apple crisp is part of our high-protein desserts collection, but it still eats like a real dessert — just with honest, modest protein from cottage cheese, eggs, oats, and walnuts.

How much protein is actually in this
About 11-12 grams of protein per serving — roughly 7g from the cottage cheese, 2g from the eggs, and the rest from the oats and walnuts. This is a dessert, not a meal replacement, so that number is honestly modest, not inflated.
Tips for a crisp that sets properly
- Blend the custard until it’s completely smooth. Thirty to sixty seconds is usually enough. Any curds you leave behind will still be curds after baking.
- Slice the apples evenly, about 1/4 inch thick, so they soften at the same pace the custard sets. Firm baking apples such as Granny Smith, Honeycrisp, or Braeburn hold their shape best.
- Bake until the middle is set and the top is golden. If you like to use a thermometer, an egg custard is done at 160°F (71°C).
- Let it rest for 10 to 15 minutes. The custard finishes setting as it cools. Cut too early and it will be soft and runny, which still tastes good but won’t hold a clean scoop.
Swaps and variations
- Nuts: pecans or sliced almonds can replace the walnuts. For a nut-free topping, use extra oats and a handful of sunflower seeds.
- Fat in the crumble: butter gives the richest flavor; coconut oil works if you prefer it.
- Sweetness: if your apples are very sweet, start with a little less maple syrup in the apple layer and taste before baking.
Protein per serving shifts slightly with any swap, and nutrition numbers are estimates that depend on the brand of cottage cheese you buy.
What to serve with it
Warm is the classic, and a scoop of cold high-protein Ninja Creami frozen yogurt on the side is a nice contrast.
Make-ahead, storing, and reheating
Bake it the day before, cover it, and keep it in the fridge. Reheat a portion in the microwave for 45 to 60 seconds, or put the whole dish in a 350°F oven for about 10 minutes to bring the topping back to crisp. It’s also good cold, straight from the fridge. Leftovers keep about 4 days. We haven’t tested freezing this one (egg custard can turn watery), so we’d stick to the fridge.
Equipment note: Leftover crisp keeps well in glass containers with lids in the fridge.

Ingredients
Method
- Preheat the oven to 375°F. Lightly grease a 9-inch baking dish.
- Toss the apple slices with the lemon juice, maple syrup, and cinnamon. Spread evenly in the baking dish.
- Blend the cottage cheese, eggs, maple syrup, and vanilla until completely smooth — no visible curds. Pour evenly over the apples.
- In a separate bowl, combine the oats, walnuts, melted butter, maple syrup, cinnamon, and salt. Sprinkle evenly over the custard layer.
- Bake for 35-40 minutes, until the custard is set and the topping is golden.
- Let cool for 10-15 minutes before serving — the custard layer firms up as it cools.

Frequently Asked Questions
Will I taste the cottage cheese?
No — blended smooth and baked into a custard, it tastes closer to a light cheesecake layer than cottage cheese.
Can I use a different fruit?
Pears work well as a swap or addition. Stick with firmer fruits so the bake holds together.
Is this good enough to serve for a real dessert, not just a snack?
Yes — this one leans more toward “actual dessert” than most protein recipes on the site, warm with a scoop of yogurt or a small drizzle of extra maple syrup on top.
