These vegan strawberry oatmeal muffins are everything I want in a quick bake — naturally sweetened with dates, no refined sugar, and ready in just 30 minutes. Juicy strawberries, creamy peanut butter, hearty oats, and melty chocolate chips all in one soft, satisfying bite. Consider this your new favorite breakfast treat.
A recent trip to the US brought back a craving I'd almost forgotten about: Peanut Butter & Jelly.
These wholesome, flourless oatmeal strawberry muffins are my little love letter to that iconic American combo — and honestly, I think they might be even better.
The strawberries bring the jammy, fruity sweetness. The peanut butter adds that rich, salty-nutty depth. The oats keep things hearty and filling. And then there are the chocolate chips — the real star of the show. They get slightly melty in the oven and then firm back up into little pockets of crunch. Do not skip them.

Why You'll Love This Recipe
- Naturally sweetened with dates – no refined sugar
- Quick and easy to make – ready in 30 minutes
- Perfect for meal prep – ideal as a breakfast on-the-go or healthy snack
- Moist and juicy – thanks to the fresh strawberries and dates
- Pleasantly filling – thanks to oats and peanut butter
- Easily customizable – see variations below
The Ingredients
- Dates: Go for soft, sticky dates — Medjool are ideal (you'll need around four) and blend up beautifully smooth. If your blender isn't super powerful, soak the dates in warm plant milk for 5–10 minutes first to soften them up before blending.
- Plant milk: Any unsweetened variety works here. I used soy milk, but oat milk, almond, or cashew all work as well.
- Peanut butter: Use an unsweetened, natural PB made from roasted peanuts — the roasted flavor makes a huge difference here. Almond butter or hazelnut butter also work if that's what you have on hand.
- Rolled oats & oat flour: The heart of this recipe — they give the muffins their chewy texture and keep you full for hours. No need to buy oat flour separately: just blitz some rolled oats in a blender until fine (a few coarser bits are totally fine!).
- Strawberries: Fresh, ripe, in-season strawberries are the move here. Frozen strawberries release too much water as they bake, which turns your muffins into a soggy mess — so stick with fresh.
- Ground flaxseeds: Our egg-free binder! They hold everything together and sneak in a bit of extra fiber at the same time.
- Sugar-free chocolate chips: I used xylitol-sweetened chips for these. Date-sweetened chocolate is also a great option if you can find it. And if sugar-free isn't a priority for you, just grab your favorite dark chocolate and chop it up — no rules here.
(Exact quantities are in the recipe card below!)
Step-by-Step Instructions
To make these fruity oatmeal and chocolate chip muffins you'll need a blender and a big bowl. If you don't have oat flour on hand, I suggest you use your blender to make it yourself first before you use it for the wet ingredients.
- Step 1: Preheat oven to 350°F (convection/fan). Add the dates, plant-based milk, peanut butter, and vanilla to a blender and blitz until you get a completely smooth, creamy mixture.
- Step 2: Wash your strawberries and chop them into small bite-sized pieces. Set aside.
- Step 3: In a large bowl, combine the rolled oats, oat flour, chocolate chips, ground flaxseeds, cinnamon, baking powder, and salt. Give it a good stir.
- Step 4: Pour the date cream into the dry ingredients and mix until well combined. Then gently fold in the strawberry pieces — try not to overmix here so they stay in nice chunks.
- Step 5: Lightly grease your muffin tin with cooking spray or a little oil, then divide the batter evenly between the cups. This makes 6 large or 8–9 smaller muffins.
- Step 6: Bake for 20–25 minutes, until the tops are golden and a toothpick inserted in the center comes out clean.
I know, I know — waiting is the hardest part. But please give them a few minutes to cool before trying to pop them out! If you're using a standard metal muffin pan, run a thin knife around the edges and they'll release cleanly. Worth every second of patience.
My personal favorite? These healthy oatmeal muffins slightly chilled, straight from the fridge, with a nice cup of coffee or latte. When they're cold, those chocolate chips snap in the most satisfying way — one of those little details that makes this recipe genuinely addictive.
Variations
The base of this peanut butter oatmeal cups recipe is wonderfully flexible. Swap the fruit, switch up the nut butter, or play with mix-ins — the possibilities are endless. Here are a few flavor combos I'm especially excited to try:
- Apple-Oat: For apple-oat muffins, replace the strawberries with one medium-sized grated apple. Increase the amount of cinnamon to 1½–2 tsp.
- Raspberry-Pistachio: Fresh raspberries instead of strawberries, chopped pistachios instead of chocolate.
- Blueberry-Coconut: Replace strawberries with fresh blueberries, peanut butter with coconut butter, and fold in coconut flakes instead of chocolate chips.
- Banana-Peanut-Chocolate: For banana oatmeal muffins, cut about 1½ bananas into small pieces and use instead of berries. Don't use overly ripe or soft bananas. Replace half of the oat flour with cocoa powder. Chopped peanuts also work great instead of chocolate chips.
FAQ
I wouldn't recommend it — frozen berries release a lot of liquid as they bake, which can make the muffins dense and gummy. If frozen is all you have, let them thaw first, drain off the excess liquid, then pat them dry before folding in. Just know I haven't tested this method myself!
I'd skip the paper liners — this batter really sticks to them and you'll lose a lot of muffin trying to peel them off. Silicone muffin cups are your best bet, or just grease a regular metal pan well.
Yes! Oats are naturally gluten-free. That said, if you have celiac disease or serious gluten sensitivity, look for oats that are certified gluten-free to avoid cross-contamination.
Store them in an airtight container in the fridge — they keep well for up to 5 days. They actually taste even better on day 2 once the flavors have had time to meld!

Notes
* You can also use another nut butter of your choice. If using peanut butter, make sure to use one made from roasted peanuts — it makes a huge difference in flavor.
** You don't need to buy oat flour. Simply grind rolled oats in a blender. It's totally fine if the result isn't super fine.
*** Sugar-free chocolate chips sweetened with xylitol work great here. Date-sweetened chocolate is also an option. If sugar-free isn't a requirement for you, any good-quality dark chocolate chunks work well.
