Banana Cream Pie Overnight Oats (High Protein)

Creamy banana cream pie overnight oats with 29g of protein per serving. Vanilla oats, sliced banana, and a white chocolate Greek yogurt ganache — tastes like banana cream pie filling, ready in 10 minutes.

Banana cream pie overnight oats are a no-cook breakfast made by mixing oats, chia seeds, protein powder, maple syrup, and almond milk, then layering with fresh banana slices and a white chocolate–Greek yogurt ganache. One serving packs 29g of protein — it tastes like banana cream pie filling but doubles as a meal-prep breakfast.

The ganache layer is what takes this from “banana oats” to “banana cream pie.” The melted white chocolate whisked into Greek yogurt sets thick overnight, like the cream filling in a real banana cream pie, while the fresh banana slices give you the fruit layer.

• Naturally gluten-free with certified gluten-free oats

Ingredients You’ll Need

(Full measurements in the recipe card at the bottom of the post.)

For the oats:

• Old-fashioned rolled oats — best texture. Quick oats work but get soggier overnight. Steel-cut won’t soften without cooking. Use certified gluten-free if needed.
• Unsweetened almond milk — neutral flavor. Oat, cashew, coconut, or regular milk all work. Fairlife skim milk works for an extra protein boost.
• Chia seeds — absorb liquid and thicken the oats overnight. Flax seeds work as a 1:1 swap.
• Maple syrup — light sweetness. Honey works as a swap. Can be reduced or skipped if you want it less sweet.
• Vanilla protein powder — I use PEScience Gourmet Vanilla (code BAILEY saves you). Any whey or plant-based vanilla protein works.
• Banana — ripe but still firm. Avoid green bananas (starchy taste) and overripe bananas (will brown and turn mushy overnight). About half a banana sliced is the right amount per serving.

For the white chocolate ganache topping:

• White chocolate chips — Enjoy Life Foods or a baking bar melts smoothest. Cheap chocolate chips clump more.
• Plain Greek yogurt — pushes the protein up and gives the topping a tangy “pie cream” feel. Vanilla Greek yogurt works for a sweeter version. Banana Greek yogurt is amazing here — a reader-tested swap.

How to Make Banana Cream Pie Overnight Oats

1. Mix the oat base. Add oats, almond milk, chia seeds, maple syrup, and protein powder to a bowl or mason jar. Stir well until the protein powder dissolves.
2. Refrigerate while you prep the topping (about 5 minutes).
3. Slice the banana. Layer the slices on top of the chilled oats.
4. Make the ganache. Microwave the white chocolate chips in 30-second intervals until just melted (don’t overcook — that’s the #1 reason it clumps). Important: before whisking in the Greek yogurt, warm the yogurt slightly in the microwave (15-20 seconds). Cold yogurt + warm chocolate seizes into clumps. Warmed yogurt mixes smooth.
5. Pour the ganache over the banana slices, cover, and refrigerate overnight (or at least 4 hours) to fully set.
6. In the morning — top with extra banana slices and eat. Cold straight from the fridge or warm briefly in the microwave.

Tips for the Best Results

1. Warm the Greek yogurt before mixing with melted chocolate. This is the #1 reason ganache fails — cold yogurt + warm chocolate seizes into a clumpy mess. 15-20 seconds in the microwave fixes it. Reader Angela figured this out and it works perfectly.
2. Don’t overheat the white chocolate. 30-second intervals in the microwave, max 1 minute total. Overheated chocolate clumps and won’t whisk smooth.
3. Use Enjoy Life Foods white chocolate or a baking bar. Cheap white chocolate chips have stabilizers that prevent smooth melting.
4. Use rolled oats, not quick oats. Rolled oats absorb evenly and stay slightly chewy. Quick oats turn to mush overnight.
5. Use a ripe-but-firm banana. Green bananas taste starchy. Overripe bananas brown and turn mushy overnight. The sweet spot is yellow with maybe one or two small brown speckles.
6. For a smoother, pudding-like base — blend the oats with the milk before mixing in the rest. Reader Christina’s tip — gives you a creamier banana-cream-pie-filling consistency.

Mix-In Variations

• Banana yogurt swap (reader favorite): Ashleigh used banana-flavored Greek yogurt instead of plain — “AMAZING!” Pushes the banana flavor harder.
• Blended base (reader favorite): Christina blends the oats and chia with the milk for a pudding-like smooth base before adding the rest. Looks more like a real banana cream pie filling.
• Less sweet: Skip the maple syrup entirely and use unsweetened coconut milk — Rachelle’s modification, “delicious.”
• Higher protein: Add 2 tablespoons of cottage cheese to the oat base — pushes protein over 35g per serving
• Banana pudding twist: Stir 1 tablespoon of instant banana cream pudding mix into the oats before refrigerating for a more pronounced banana cream pie flavor
• Graham cracker crust: Crush 1 graham cracker and press into the bottom of the jar before adding the oats for a true pie-style version
• Dairy-free: Use coconut yogurt, vegan white chocolate chips, plant-based protein

How to Store and Meal Prep

• Fridge: Store sealed jars for up to 3-4 days. The ganache holds beautifully.
• Meal prep tip: Make 3-4 jars at once. Add fresh banana slices in the morning, not the night before, to prevent browning.
• Best containers: Wide-mouth mason jars (16 oz) show off the layers.
• Save the topping bananas for the morning to keep them fresh and prevent browning.
• Don’t freeze — banana texture suffers when thawed.
