Our oatmeal raisin marshmallow cream pies bring together chewy spiced oatmeal cookies and a light vanilla marshmallow filling for a handheld dessert that tastes like a lunchbox classic rebuilt from scratch. The cookies stay soft for days because the oats and brown sugar hold moisture, while the filling pipes cleanly without weeping. You get a make-ahead treat that travels well and freezes better than most packaged versions.
This recipe scales down easily and uses pantry staples, so you won’t need a special shopping trip. The filling sets firm enough to slice yet yields like a marshmallow when you bite in. If you enjoy breakfast-style bakes, our overnight oatmeal is a good companion meal-prep idea. Making this oatmeal raisin marshmallow cream pies at home is surprisingly straightforward once you know the key steps.

Ingredients You’ll Need
- 115 g unsalted butter, softened — gives tender crumb and carries spice flavor
- 100 g light brown sugar — adds moisture and caramel notes to the oats
- 50 g granulated sugar — supports spread and light browning
- 1 large egg (50 g) — binds the dough and sets the structure
- 1 tsp vanilla extract — rounds the spice and filling flavors
- 95 g all-purpose flour — base structure for the cookies
- 1/2 tsp baking soda — lifts the cookies slightly during bake
- 1/2 tsp ground cinnamon — warm spice that pairs with raisins
- 1/4 tsp salt — balances the sweetness
- 120 g old-fashioned rolled oats — chewy body, not instant texture
- 80 g raisins — plumped sweetness distributed through the dough
- 115 g marshmallow crème (jar) — base for the filling
- 60 g unsalted butter, softened (filling) — whips the crème to a spreadable texture
- 120 g powdered sugar — stabilizes the filling and reduces stickiness
- 1/2 tsp vanilla extract (filling) — mirrors the cookie flavor
Ingredient Substitutions
Old-fashioned rolled oats: Replace with an equal weight of quick oats if that is what you have. Quick oats absorb liquid faster and produce a denser, less chewy cookie with a finer crumb. Expect the bake time to drop by about 2 minutes because the smaller flakes hydrate sooner. The oatmeal raisin marshmallow cream pies works well for weeknight cooking when time is limited.
Raisins: Swap for an equal weight of finely chopped dried cranberries to add tartness against the brown sugar. Cranberries are firmer and less sweet, so the cookies read brighter and slightly less caramel-like. No change to bake temperature or timing is needed. Storing leftover oatmeal raisin marshmallow cream pies correctly keeps it tasting good for days.
Marshmallow crème: Use 90 g mini marshmallows melted with 1 tbsp water over medium-low heat as a substitute. The melted mix is looser while warm and firms as it cools, so chill it 10 minutes before whipping with butter. The filling will be a touch less sweet and more elastic. For the best results with this oatmeal raisin marshmallow cream pies, read through all the steps before starting.
Light brown sugar: Replace with dark brown sugar in equal weight for a deeper molasses flavor and slightly softer cookie. Dark sugar holds more moisture, so add 1 tbsp flour if the dough feels slack. The cookies will brown faster, so check at 10 minutes. If you enjoyed this, our cherry almond oatmeal is worth trying next.
Step-by-Step Instructions
- Heat the oven to 180°C / 350°F and line two baking sheets with parchment. Cream 115 g butter with both sugars on medium speed for 2 minutes until pale and fluffy.
- Add the egg and 1 tsp vanilla, beating on low until just combined with no streaks. Overbeating here adds air that makes cookies spread too thin.
- Whisk flour, baking soda, cinnamon, and salt in a separate bowl, then fold into the butter mix on low. Stir in oats and raisins until evenly distributed and the dough looks shaggy but cohesive.
- Scoop 24 level tablespoons of dough onto the sheets, spacing them 5 cm apart. Bake 11–13 minutes until edges are golden and set but centers look slightly underdone.
- Cool cookies on the sheet for 5 minutes then move to a rack. They firm as they cool, so avoid moving them early or they break.
- Beat 60 g softened butter with powdered sugar and 1/2 tsp vanilla for 2 minutes on medium. Add marshmallow crème and whip 1 minute until smooth and pipeable.
- Pair cookies by size. Pipe or spoon 1 tbsp filling on the flat side of one, press the second cookie gently to spread to the edge. Set pies on a tray and chill 20 minutes to firm.
Pro Tips
Chill the shaped dough 15 minutes before baking if your kitchen is warm, since firm fat slows spread and keeps the cookies thick enough to sandwich.
Use a plain round tip for the filling so the layer is even and the edges stay clean when pressed. A reliable piping method keeps the cream from squishing out the sides.
Measure oats by weight, not volume, because packed cups vary by 20 g and change the dough hydration. Consistent oats mean predictable chew.
Store unfilled cookies and filling separately if making ahead, then assemble within 30 minutes of serving for the softest bite. Our oatmeal cookie smoothie uses the same spice profile if you want a drink version.
Common Mistakes to Avoid
Baking until the centers look fully done yields hard cookies; pull them when the middle still looks slightly soft because residual heat finishes them. A oatmeal smoothie won’t help here, but the visual cue will.
Overfilling the pies makes the cream leak when pressed; keep to 1 tbsp and stop pressing once you feel resistance. Too much filling also softens the cookie faster.
Skipping the chill after assembly means the cream stays tacky and the pies slide apart in the container. A short rest sets the structure for clean packing.
Serving Suggestions
Plate the pies with a cold glass of milk or a weak coffee to balance the sweetness. For a dessert board, cut them in half to show the cream layer next to cucumber bread slices for contrast. They also pack well in lunchboxes with fruit.
Storage and Reheating
Keep assembled pies in an airtight container in the fridge for up to 4 days; the filling is dairy-based so room temperature storage is limited to 2 hours. Freeze单个 pies wrapped in parchment for up to 2 months and thaw at room temperature 20 minutes. No reheating is needed; serve cold or let sit 10 minutes to soften. Our tropical oatmeal is a bright breakfast next to leftover pies.
Recipe Variations
Spiced Apple Version
Replace raisins with 80 g finely diced dried apple and add 1/4 tsp ground nutmeg to the dough. The apple gives a firmer chew and tart-sweet note that pairs with the cinnamon. Bake time stays the same but expect a slightly lighter cookie color.
Chocolate Dipped
After assembly and chill, dip half of each pie in 100 g melted dark chocolate and set on parchment 10 minutes. The shell adds snap and cuts the cream’s sweetness. Use a 55% bar so the coating doesn’t overpower the oat flavor.
Maple Filling
Swap 1 tsp vanilla in the filling for 1 tbsp maple syrup and reduce powdered sugar by 15 g. The filling takes a woodsy note and stays slightly softer, so extend the chill to 30 minutes. This version pairs well with irish cream as a grown-up drink.

Ingredients
Instructions
-
Heat oven and line sheets
Heat the oven to 180°C / 350°F and line two baking sheets with parchment paper. This preheats the oven fully so the cookies bake evenly from the start.
-
Cream butter and sugars
Cream 115 g butter with both sugars on medium speed for 2 minutes until pale and fluffy. The mixture should look light in color and hold soft peaks when the beater is lifted.
-
Add egg and vanilla
Add the egg and 1 tsp vanilla, beating on low until just combined with no streaks. Overbeating here adds air that makes cookies spread too thin, so stop as soon as the batter looks uniform.
-
Fold in dry ingredients
Whisk flour, baking soda, cinnamon, and salt in a separate bowl, then fold into the butter mix on low speed. Mix only until no dry flour remains to avoid toughening the dough.
-
Stir oats and raisins
Stir in oats and raisins until evenly distributed and the dough looks shaggy but cohesive. The raisins should be spread through the mass with no clumps of dry oat left.
-
Scoop and space dough
Scoop 24 level tablespoons of dough onto the sheets, spacing them 5 cm apart. This gives room for the cookies to spread without touching during bake.
-
Bake the cookies
Bake 11–13 minutes until edges are golden and set but centers look slightly underdone. Cool cookies on the sheet for 5 minutes then move to a rack, as they firm as they cool and break if moved early.
-
Make marshmallow filling
Beat 60 g softened butter with powdered sugar and 1/2 tsp vanilla for 2 minutes on medium. Add marshmallow crème and whip 1 minute until smooth and pipeable with a creamy sheen.
-
Assemble and chill pies
Pair cookies by size, pipe or spoon 1 tbsp filling on the flat side of one, and press the second cookie gently to spread to the edge. Set pies on a tray and chill 20 minutes to firm the cream so they pack cleanly.
