Giant Pokemon Pokedex Rice Krispies Treat for Ash Ketchum’s Birthday

Forgive me for using this word, but I honestly think this is the most “extra” thing I have ever done or created – and I am in love with it! 😍 This took so long and so many bags of marshmallows to create, but I definitely think it was worth it in the end.

I made a GIANT POKEDEX RICE KRISPIES TREAT. Honestly, I don’t think anything I make will ever top this, but I might be biased due to my love of Pokemon 😂

I started to brainstorm a new Pokemon recipe when I found out that the 22nd of May is apparently Ash’s birthday, and the original Pokedex is one of my favourite Pokemon-related items (even though I’ve never owned any kind of toy version 😢), so it’s really no surprise that this is its second appearance on the blog.

Whilst time-consuming, this recipe really isn’t very difficult at all, and it’s actually quite calming to just play around with fondant all day long! It’s like playing with Play-Doh for grown-ups (not judging any adults who still play with Play-Doh, though – we have some at our place!), except you can eat the final creation AND it will taste good!

So if you’d like to make the most sugar-filled treat to show your appreciation of the Pokemon franchise – or even just the 90’s in general, keep reading 😋


♡ A 9×12 inch baking pan
♡ Around four 280g bags of Pascall marshmallows (you can get away with a little less though. as I didn’t use many pink marshmallows, plus I ate a lot)
♡ 240g butter, cut into 60g pieces
♡ 2 + 2/3 cups of Rice Krispies/Bubbles cereal
♡ Red food colour (Chefmaster’s Super Red or Wilton Red-Red Icing Colour both work well)
♡ Black, white, blue, red, green, and yellow fondant
♡ Red, yellow, and blue circle sprinkles (you could also use fondant)
♡ Black food marker (I use Chefmaster’s)
♡ Fondant rolling pin and pencil
♡ Regular spatula, and an angled spatula to move your fondant pieces
♡ Lots of baking paper, and cooking oil spray
♡ Small knife and large knife
♡ Heatproof bowl

1. Place your tray on top of some baking paper and trace around the bottom of it. Do the same to a second piece of paper, then set them aside. Line your tray with baking paper and make some of the paper hang over the edge so you can use that to easily take out the entire piece later on. You may want to spray with cooking oil for good measure; this mixture is very sticky so I like to be extra sure it won’t stick to the pan.

2. Place 60g of butter and a handful of white marshmallows from one packet in a heatproof bowl and microwave in 30 second intervals until completely melted. Stir after each interval, then add the rest of the white marshmallows from that same packet as the others dissolve, plus a couple of pink ones.

3. Once the marshmallows and butter are melted and stirred together, add in your red food gel colour until you get a true, rich red colour. It might take a bit of food colour, but this is the only red food colour that I know that works so well, so it is worth every penny and every drop! Once your mixture is sufficiently stirred, add in 2/3 cups of Rice Krispies/Bubbles cereal and stir until coated.

4. Pour into your pan, using your spatula to scrap out all the mixture. Press down with some baking paper and a flat hand to ensure it gets into those corners. If you’re happy with a thin slice for your Pokedex, you could stop here, but I decided to repeat steps 2 and 3 again (using another 60g of butter, and all the white marshmallows plus a few pink from your second packetto make mine a little thicker. Once the mixture has cooled slightly, place in the fridge to set.

5. Grab one of the pieces of baking paper that you traced the outline of your tray onto and cut it out. You can draw all the buttons and lights of the Pokedex freehand if you wish, but I got up a photo on my laptop and enlarged it until it was the same size of the baking paper I had, then traced around all the lines. Keep the photo nearby so you can refer back to it when adding your fondant pieces.

6. Cut out the large square on the baking paper that will be your screen. Roll out some white fondant onto a sheet of baking paper, then place that square on top and cut around the edges with your small knife. Wipe your knife and rolling pin.

Place the white fondant square aside using your angled spatula, then roll out some black fondant. Cut out the smaller square that you drew inside your large square, place that on top of your black fondant, then cut around it with your small knife and place that piece in the middle of your white fondant square.

7. Roll out a small amount of black fondant and cut three tiny lines out, that will go just underneath the screen. The actual Pokedex has four lines here, but I wasn’t able to get mine thin enough to fit four in without them really flimsy, so I did three instead. Place them onto your white fondant, just underneath and to the right of the black fondant.

8. Cut out the black plus symbol buttons and the large dot that is to the left of it out of your baking paper outline. Roll out some more black fondant, then cut those two pieces out with your small knife.

Smooth any harsh edges with your finger or the side of the knife. Wipe your knife and rolling pin so no excess black fondant remains. You may also want to get a new piece of baking paper to roll your fondant onto to ensure that the different coloured fondants don’t mix with each other.

9. Cut out the rectangle shape from your baking paper that sits between the black dot and plus symbol buttons on the Pokedex. Roll out some green fondant, then cut out that shape with your small knife. Wipe off your knife and rolling pin once again.

For the thin red and blue lines that sit underneath the screen, I just grabbed a small pinch of red and blue fondant, rolled it between my fingers then flattened it slightly.

10. Cut out the circle piece of your baking paper that will go in the top left corner of your Pokedex. Roll out some white fondant, place the circle on top, then cut it out with your small knife. Wipe of your knife and rolling pin, then cut out the slightly smaller circle that you have drawn inside that one.

11. Roll out some blue fondant then use your smaller circle as a stencil to cut around with your knife. Smooth out any edges as you deem necessary, then place the blue circle on top of the white one. Grab a tiny pinch of white fondant, roll it into a ball, then flatten it, and place that in the top left corner of your blue fondant circle.

12. Once your Rice Krispies have set, take them out of the fridge, and carefully use the overlapping baking paper to lift it out of the pan. Referring back to your picture of a Pokedex, place all of your fondant shapes in their correct places on your Rice Krispies treat by using your angled spatula to ensure you don’t warp their shape. If you’re worried about them sliding off, just splash a tiny amount of water on the bottom of the fondant.

13. Get one red, one yellow, and one blue circle sprinkle and place them in the correct order at the top of the Pokedex, then get another three red sprinkles to go above and below the screen. Place your Rice Krispies treat to the side, and start working on the next piece!

1. Re-line your tray with more baking paper and spray as required. Remember to leave a large amount of paper hanging over the edge to help you get the finished product out easier later. Place another 60g of butter and handful of white marshmallows from your third packet into your heatproof bowl, then microwave for 30 seconds.

2. Add in your red food colour until you reach the same colour as the left piece, then mix in 2/3 cup of Rice Krispies, pour into your pan, and press down into the edges with your hand over some baking paper. Place in fridge to set.

If you decided to double the thickness with your left side, do the same with the right, meaning you should have no butter or cereal left, and only a small handful of pink marshmallows.

3. Once your mixture has set, take it out of the pan and place it next to your left side. Using your picture of a Pokedex as a guide, cut off some of the top and bottom of your right side piece, including the part that “dips” down. Clearly, words are failing me right now, but when you look at both sides of the Pokedex you’ll know what I mean 😂 Once you’ve cut your

4. Grab your second piece of baking paper from step 1 for the left side, and cut along the lines you drew earlier. Using your photo of the Pokedex and the right side of your Rice Krispies treat as a guide, cut off the top and bottom parts of your baking paper the same way you did to the treat, so that they are the same size.

5. Enlarge your photo of the Pokedex again and trace around all the necessary shapes for your buttons, including the lines that go on the white and blue rectangles. Cut out out the large black rectangle, and the two medium sized ones, from your baking paper.

6. Roll out a large amount of your black fondant and place your three rectangle pieces on top, then cut them out with your small knife. Move them to the side, always remembering to use your angled spatula so your fingers don’t warp the fondant pieces. Wipe off your rolling pin and knife.

7.  Cut out the circle shape from your baking paper, roll out a small piece piece of yellow fondant, then use that circle as a stencil to cut out a yellow fondant circle. Soften any harsh cutting lines with your fingers or the side of your knife as best as you can. Wipe the rolling pin and knife.

8. Cut out the white rectangle from your baking paper, roll out some white fondant, then cut that shape out of the fondant. Wipe off your knife and rolling pin, then cut out the large blue rectangle from your baking paper.

9. Roll out your blue fondant, then cut out the large rectangle using the stencil. Grab two small pinches of black fondant between your fingers and roll them in between your fingers, then flatten them slightly so they don’t roll off the Rice Krispies Treat.

10. I would recommend waiting for the fondant to dry slightly before you write on it with your food marker, to prevent the fondant from softening under the weight and moisture of the marker.

If you don’t have time to wait, just use very light and small strokes to draw the necessary lines on the blue and white rectangles. Remember to refer back to your picture of a Pokedex to ensure that your lines are spaced correctly!

11. Place all your fondant pieces in their necessary places, remembering that you can splash the back of them with a few drops of water to ensure that they stick. Then, find a plate (or, in my case, another baking tray) that is big enough to fit both Rice Krispies treats on it, and place the two sides next to each other!

Be quick and careful when doing this as they are both quite thin and will start to bend if you pick them up too roughly, or hold onto them for too long!

Whew! If you’ve made it this far, I’m impressed! As much as I LOVE the outcome of this recipe, it did take quite some time, and a few ingredients to make. I really do think the finished result is worth every second, though. This would go so perfectly at a Pokemon and 90’s theme party! AND, if anyone of you ARE having a party with one of those themes, I’ll be expecting my invite in the mail 😜

Until next time,

  1. Whoa! Impressive! That really is “extra.” I think the most exciting treat I’ve ever baked is a chocolate cake with frosting and gummy bears.


    • Except for ONE! There’s actually meant to be FOUR little black lines under the screen on the left side, but I couldn’t cut the fondant thin enough to fit all four 😭 As a true Pokemon fan it really gets to me, but other than that, I’m really happy with it!
